ICE ban not needed, you are buying it for the last time

2010-2019 “Electric vehicles are no good because there’s nowhere to repair them, who will fix them?”
Then came EV Clinic:
2019 – “Electric vehicles are no good, you see, they need repairs once every 8 years.”
“You see, they’re no good as soon as you repair them, how would you make a living?”
Trolls and bots always have the easiest argument as an excuse, but they don’t know that I make a living precisely from fossil-fuel “never fails anything” service. Every summer, for the past 10 years, we’ve been dealing with an invasion of automatic gearboxes falling apart at just 100,000 km due to planned material fatigue and intense heating, leading to ruptured pipes, sensors, and other components. There’s no comment needed, it’s a well-known “peon’s” excuse, “the more you maintain it, the better it is.” Because junk cannot be improved even if you sleep next to it, no “regular maintenance by a skilled mechanic” helps, only a redesign of the system where the manufacturer intentionally weakened the material or planned the failure of a component. The only gearboxes that come very little or not at all are Japanese ones – Mazda, Mitsubishi, Toyota, Honda, etc. And why is that? Because they don’t have planned design defects that people love, especially in the Balkans. They don’t have them because the manufacturers have a completely different, less greedy strategy. With this European “fair” strategy, fewer and fewer parents are sending their children to college because they’ve had to replace the turbine three times, the mechatronic gearbox twice, and now the DPF is clogged. That’s why our future is secure because every day we have 10 gearboxes coming in, more and more defective fossil powertrains, parts getting more expensive and harder to obtain, and our hourly rate is getting higher. Some gearboxes are statistically the worst and most often irreparable, and DSG DQ200 stands out here. Most defects cannot be resolved if there’s a kurzschluss on the ceramic of the baradie chips. Some have brought in already opened “electronic cabbages” expecting miracles, but only a few defects can be repaired. Surely the junk king here is Mercedes with its 7G and FCVT gearboxes. The 724 7G is irreparable. Also, the 9G, it has a fault counter, and if one fault appears more than 20 times, it activates the OTP lock, and you have to buy a new electronic unit, but Mercedes martyrs don’t know that it’s no longer possible to buy just the electronic unit, you have to buy the whole gearbox (10,000€). Used 9G modules in the FBS4 crypto immo system cannot be cloned because of the Renesas baradie Jtag lock processor. As I said, some will buy the new generation of fossil vehicles for the last time, no need to bother with education. Education will be a minus in the bank account.

2010-2019 “Elektricna vozila nevaljaju jer nemaš gdje popraviti, tko će to popravljati”

Došao EV Clinic:

2019- “Električna vozila nevaljaju vidis da se moraju popravljati jednom u 8 godina”

“Vidis da nevaljaju cim ih popravljate, od čega bi živjeli.

Trolovima i botovima je izgovor uvjek najlakši argument samo oni neznaju da ja živim upravo od fosilnog “nikad ništa” servisa. Svako ljeto nas vec 10 godina poprati invazija automatskih mjenača koji se raspadaju vec na 100k KM jer zbog planiranog zamora materijala i intezivnijeg grijanja dolazi do pucanja vodova, senzora i ostalih komponenti. Ne postoji tu nikakva opaska, dobro poznata kmetska traljava opaska, “kolko ga odrzavas toliko je bolji”. Jer skart ne moze biti bolji ni da spavaš kraj njega, nikakvo “redovno odrzavanje kod pravog majstora” i ne pomaze nista osim redizajna sustava gdje je proizvodjac namjerno stanjio materijal ili isplanirao otkazivanje komponente. Jedini mjenjaci koji vrlo malo ili uopce ne dolaze su Japanski. Mazda, Mitsubishi, Toyota, Honda itd… a zasto, zato jer nema planirano dizajniranih defeksta koje narod voli, pogotovo na balkanu. Nema ih jer proizvodjači imaju totalno drugu strategiju, manje lihvarsku. Sa ovom europskom “pravednom” strategijom sve manje roditelja salje klince na fakultet, jer vec 3 puta mjenja turbinu, 2 puta mehatronik mjenjaca i sad jos se i dpf začepio. Zato je nama buducnost osigurana jer dnevno dolazi i 10 mjenjača, sve je vise defektnijih i učestalijih fosilnih pogonskih sustava, dijelovi sve skuplji i teže dobavljivi a nasa satnica sve skuplja. Neki mjenjaci su po statistikama najgori i najcesce nepopravljivi, tu se ističe DSG DQ200. Vecina defekata se ne moze rijesiti, ako je kurzschluss na keramici na baredie čipovima. Neki su donosili kupus od elektronike vec otvaran ocekivali čuda, medjutim nekolicina kvarova je samo popravljiva. Svakako škart king je tu Mercedes sa 7G i FCVT mjenjacima. 724 7G je nepopravljiv. 9G takodjer, ima brojač za pojavljivanje greske, ako ae jedna greska pojavi vise od 20 puta aktivira OTP lock i moras kupiti novu elektroniku, samo sto Mercedes mučenici ne znaju da više nije moguce kupiti samo elektroniku vec morate cijeli mjenjač (10000€). Rabljen 9G modul u FBS4 crypto immo sustavu nije moguce klonirati jer je Renesas baredie Jtag lock processor. Kao što rekoh, neki će fosilce nove generacije kupiti zadnji put, ne treba se ni truditi oko edukacije. Edukacija ce biti minus na računu banke.

AUTOMOTIVE OPTIMIZATION means more bankrupt owners


AUTOMOTIVE OPTIMIZATION is becoming increasingly aggressive throughout the automotive industry. To the general public, it may mean “potential” savings, to us, a potential “sponsor,” and to manufacturers, a “pat on the back” and abundant profits. Your vehicle is 2 kilos lighter, you are on a diet, and you have 2000 square meters less of inherited land (approximately 1200€ less). This is because the Li-ion 12V 70Ah battery, which replaced the old lead-acid one, discharged while the vehicle was at the service, and you cannot recharge it as it is not designed for non-invasive charging. Although this battery has proven to be extremely reliable, its BMS lacks an OTP lock like VW, Mercedes, and other junk, which would require a BMS reset. Fortunately, in this case, it is sufficient to unscrew the cover, recharge it directly at the terminals, and physically disconnect the BMS connector for a reset.

As people do not complain about the increasing junk in the automotive industry, especially in fossil-fuel-powered vehicles, we expect that soon the light switch will cost 8000€, a spark plug 20€ but malfunctioning, which the mechanic mounts at his own expense six times, the MAF and MAP sensors with Bluetooth will cost 5600€, and we will also follow the “acceptable prices” for the labor time. #peopleloveit

AUTOMOTIVE OPTIMIZACIJA, na latinskom “Ipsum Ti’metnem”, je popraćena kroz automotive industriju sve agresivnije i agresivnije. Običnom narodu to znači “potencijalna” ušteda, nama potencijalni “sponzor” a proizvodjačima “pršut na čelo i love u izobilju”. Vaše vozilo je lakše 2 kile, vi na dijeti i 2000 kvadrata djedovine manje (cca 1200€). Jer Li-ion 12V 70Ah akumulator koji je zamjenuo stari olovni se isprazni u mirovanju jer je vozilo bilo na servisu, i ne možete ga napuniti jer nije dizajniran da ga punite bez invazivne metode otvaranja i punjenja. Iako je se ovaj aku pokazao ultrapouzdanim, BMS nema OTP lock kao VW Mercedes i ostali skart pa da se mora i BMS resetirati sto je poprilicno pohvalno (inace bmw je tu najmanji lihvar po pitanju programiranih kvarova, ali ne znaju napraviti pouzdan dizel motor). Ovdje je dovoljno odsarafiti poklopac , dopuniti direktno na terminalima i fizicki odpojiti konektor BMS da se resetira. S obzirom da se narod ne buni na sve vise skarta u autoindustriji, pogotovo u fosilnim pogonima, uskoro ocekujemo da ce prekidac za svijetla biti 8000€, zamasnjak 20€ ali neispravan kojeg mehanicar o svom trosku montira vec 6 puta, MAF i MAP senzor na bluetooth 5600€ a i mi cemo popratiti “prihvatljive cijene” radnog sata. #narodtovoli

HYBRID GREENWASHING – Deceptive anti-electrification and unsustainability

Dear Balkan people (and other), the path to electrification and sustainability, as paid propaganda reviews bashing EVs and praising hybrids told you, is a global deception and a path to poverty. Commercial electrification of “dinosaurus” powertrainds, where the worst solutions from both worlds reside, with underdesigned ultracomplex drivetrains lacking redundant protection against overheating, wear, and harmful operation, is not the way to the sustainable electrification but the oposite. Communicating with colleagues in the mechatronics industry, the situation is no better with the latest generation fossil fuel car offerings from the EU “scrap” market, and service demands are growing, leaving every workshop overwhelmed. Many refuse to even accept anything produced from 2019 onwards (as we have already recommended), as even oil changes are risky due to poor oil flow systems that can destroy an engine costing which costs €32,000 (CRT) for an Audi. The “moderate quality” of junk and “prototype” ideas funded and tested by owners is beyond the reach of anyone’s budget.

Now I am 100% sure that banning the sale of fossil vehicles is NOT NECESSARY; it’s pure EU nonsense. I am 100% certain that the EU fossil vehicles with Euro norms and hybrids will be bought by domestic customers for the LAST TIME because the gold lesson “hitting the pocket” is best within our mentality. Mainstream media, through moderate disinformation and bought reviews by legacy car makers, imposed the general misconception of “hybrids” and that manufacturers and their quality offerings are completely fine. However, they are not, and it will backfire on everyone. Remember, banning is not necessary because you have purchased fossil fuel junk for the last time. Shortages of junk parts, increasing frequency of component/sensor failures, and other issues, waiting for parts for months, and the lack of “right to repair” and “parts supply” are your path to driving a Golf 4 SDI, Honda Civic ’95, or something from the EV lineup.

I repeat, repairing EVs, old fossil vehicles, or even REX hybrids is far easier. However, all PHEVs, MHEVs, and new fossil vehicles have become bottomless pits and a recipe for self-destruction (fossil rape syndrome when you are ashamed of maintanance costs). From the beginning, I have no emotional attachment to anything except quality drivetrains; we call out junk even when it comes to EV powertrains. With this approach, we have attracted a large number of colleagues in the industry, from apprentices to shop owners. A large number of “whistleblower” teams have come forward with incredible data and statistics, even those that Toyota skillfully conceals, which we will publish in a mega edition. We invite all of you from authorized service centers to come forward in large numbers, so we can debunk the mythology of hollow mainstream stories and the “modern quality” that no longer exists. Perhaps it is even time for a podcast with industry experts, mechanics, and mechatronics professionals whose voices have been taken away by “car enthusiasts,” denying them access to field information and real statistics from the workshop lift, not some ADAC statistics or other car portal nonsense.

The collection of images from the post represents damages totaling around €400,000 to the Hybrid owners where not any possible “fuel savings” can save them. Some failures are irreparable, making the vehicles fit for scrap. I have been digging through the records for four hours, and this is only a portion of the requests, with an exponential increase. We cannot respond to all of you, and we fail to repair a small number of vehicles. We work 12 hours a day, and besides the repairs, stress comes from owners who don’t follow guidelines, calling us without knowing the vehicle’s make, model, year, or error code printouts from diagnostics. Taking a photo of the tachometer IS NOT AN ERROR CODE PRINTOUT. We will have less time to respond, and the recommendation is to contact us only via email with all the necessary information; otherwise, you may not appreciate “our approach” of communicating. The path to electrification is directly through EVs (from the recommended list), and “German or EU quality” has not existed for years. Now imagine the complexity of hydrogen propulsion, where you will need an even more complex service center with 30 certificates and 2 astronauts to fix a stuck valve, while the electric drive is powered by electricity produced three times more expensively, “filled up in 5 minutes,” but you spend 2 months in the service (a topic for the future).

Dragi balkanski ( i ostali) narode, put do elektrifikacije i održivosti kako su vam plaćene propagandne recenzije koje pljuju EV a veličaju hybride govorile da je to putem hybrida je svjetska navlakuša i put do siromaštva. Medjutim elektrifikacija nije kroz komercijalnu elektrifikaciju dinosaura gdje je u pogon smješteno najgore riješenje iz oba svijeta sa poddizajniranim ultrakompleksnim pogonskim sustavima bez redudantne zaštite od pregrijavanja, trošenja i pogrešnog štetnog rada. Komunicirajući i sa kolegama mehatroničarima iz branše situacija nije ništa bolja ni sa fosilcima zadnje generaciie iz EU skart ponude a posla po servisima je sve više i svi se sve zatrpaniji. Mnogi ne žele ni primiti nista u servis sto je proizvedeno od 2019 godine do sada (sto smo vec preporucili), jer sama izmjena ulja je rizicna zbog lošeg sustava protoka ulja gdje overpressure razbije motor koji za Audija kosta nov 32000€ (CRT). “Umjerena kvaliteta” škarta i “prototip” ideja koju financiraju vlasnici je izvan bilo čijeg balkanskog budžeta. Sad sam 100% siguran da zabrana prodaje fosilaca UOPĆE NIJE POTREBNA i čista je EU nebuloza. 100% sam siguran da EU fosilce sa Euro normama i Hybride domaća ekipa kupuje ZADNJI PUT jer lekcija “po džepu” najbolja funkcionira na naš mentalitet. Mainstream mediji umjerenim dezinformiranjem i kupljenim recenzijama su nametnuli “hybridno” opće mijenje da je ponuda proizvodjaca i kvaliteta sasvim ok, medjutim nije i razbit ce se svima o glavu. Zapamtite, zabrana nije potrebna, jer škart ste kupili zadnji put. Nestašica škart dijelova, frekventnost sve veceg broja kvarova komponenti/senzora i ostalih dijelova, čekanje dijelova mjesecima i ostali problemi na koje nemate pravo “right to repair” i “parts supply” je vaš put da ponovno vozite Golf 4 SDI, Hondu Civic 95’ ili nešto od EV ponude. Ponovno ponavljam, daleko je lakse repariti EV, starog fosilca ili cak i REX hybrida, medjutim svi PHEV, MHEV i Novi fosilci su postali rupa bez dna i recepat za samoubistvo (fosilni rape sindrom). Od početka nemam emotivnu povezanost ni sa čim osim sa kvalitetnim pogonima, škart prozovamo i kad je struja u pitanju. Sa tim pristupom privukli smo veliki broj kolega iz struke od segrta do vlasnika servisa, veliki broj “whistleblower” ekipe je se javilo sa nejvjerovatnim podatcima i statistikama koje čak i Toyota vjesto krije koje cemo objaviti u mega izdanju. Mi vas pozivamo da se javite u sto vecem broju iz svih ovlaštenih servisa da razbijemo mitologiju šuplje mainstream priče i “moderne kvalitete” koja vise ne postoji. Mozda je čak i vrijeme za podcast sa stručnjacima branše mehanicara i mehatronicara kojima su “automobilisti” oduzeli pravo na glas, oduzeli pristup informacijama sa terena i realne statistike sa dizalice ne neke ADAC statistike ili autoportal lupetanja. Kolekcija slika iz posta od prilike predstavlja stetu vlasnicima oko 400.000,00€, neki su kvarovi nepopravljivi i vozila za smeće. Kopam vec 4 sata po evidenciji i ovo je samo dio zahtjeva, a porast je eksponencijalan. Ne stignemo vam svima odgovoriti, mali broj vozila ne uspijemo ni rijesiti, radimo 12 sati dnevno i stres nam rade osim kvarova i vlasnici koji ne slusaju smjernice da ne zovu ako ne znaju koje vozilo i model voze, godinu i ispis gresaka sa dijagnostike. Slikanje tacho sata NIJE ISPIS GRESAKA. Sve manje vremena ćemo imati da vam odgovaramo i preporuka je samo kontakt putem email sa svim informacijama, u protivnom vam se nece svidjeti “nas pristup” . Put do elektrifkacije je direktno na EV (sa liste preporuka) a “svabska kvaliteta” ne postoji vec godinama. Sad jos zamislite kompleksnost hydrogen pogona gdje ce vam trebati jos kompleksniji servisni centar, sa 30 certifikata i 2 astronauta da poprave jedan ventil koji je zastekao gdje je elektropogon pokretan 3x skuplje proizvedenom strujom “koju tankas 5 minuta” ali visis u servisu 2 mjeseca (buduca tema)

Tesla’s powertrain: Defying limits, rewriting legacies for 600000km on original battery.

Finally, the embodiment of what we already knew was possible but were waiting for the physical manifestation of the argument: a Tesla with its original battery and 600,000 km on the clock. A complete stranger entrusted us with a Tesla from Vienna, arriving on a tow truck without any supervision, solely based on trust from Google. Although the car was still drivable, it had a limited range of 100 km. It was the first time we personally documented such an event, and you have the honor of being acquainted with it. We were able to confirm through multiple analyses and verifications, following the owner’s statement that the battery remained untouched, as we were curious about its maximum lifespan threshold.

We had an inkling that the first-generation 1.5 battery could handle around 400,000 km before requiring servicing. However, this was mostly in cases where moisture infiltration or wiring damage were expected causes of failure. But this situation goes beyond all previous scales because the battery, hermetically sealed and free from moisture infiltration for the first time, arrived with only 10 degraded cells out of a total of 7,104 cells. These cells, due to increased internal resistance, caused significant “voltage relaxation” oscillations after periods of rest, resulting in a “brick short” discharge of one group of 74p cells, triggering the BMS_u029 flag. Without completely dismantling the entire block, these 10 cells will be replaced through a special extraction process and prepared for a bench test on a Solar UPS system. The block from the previous Tesla, which passed the gladiator bench test with an approximate capacity of 200 Ah, will be inserted into this battery pack, thus closing the loop of recycling and repair.

The battery currently operates at a capacity of 67 kWh or 195 Ah CAC, which represents approximately 11% degradation or 89% state of health (SOH). Interestingly, the first motor, previously mentioned as the P-Train MECH (not RMN), was only replaced at 500,000 km due to a humming bearing, and a new RMN motor was installed under warranty. This serves as further confirmation that Tesla’s LDU is an extraterrestrial overkill, ensuring the same quality even in the RMN model (Remanufactured). Tesla truly reigns as the king of the road and the automotive revolution, disrupting the entire legacy mindset of “moderate quality” and other imposed criteria by legacy groups, where the goal is to manufacture a vehicle that lasts only until the warranty expires, forcing you to discard and purchase a new one.

Today, fossil vehicle components are manufactured and tested up to 180,000 km in simulated environments. If they surpass this threshold, the system is deemed unsuitable for commercial sales because there is “no owner on a subscription.” On the other hand, everything we have seen, analyzed, repaired, and dismantled from Tesla demonstrates an absolute open-source contrast. Here, after 9 years and 600,000 km, the battery remains usable, having amortized the entire vehicle, and there was no need to replace the entire battery pack, as the infodemic often claims. Furthermore, we considered that the vehicle’s air conditioning was malfunctioning, and the lack of adequate cooling could have caused damage to a few cells. Currently, there is no powertrain in the world that surpasses their quality standards, and for the past 10 years, they have been relentlessly advancing, innovating, and raising the bar that not even the most established manufacturers can keep up with.

For the past 10 years, we have been hearing from mainstream infodemic spreaders that batteries cannot be repaired, that they are entirely discarded, that they cost more than the vehicle (only with the Nissan Leaf), that their lifespan is only 200,000 km, that they only last a few years… However, when we transitioned from maintaining diesel junk to EVs, every day of exploration brought enlightenment. We needed tangible confirmation, and for you, who sought the herald, here it is.

HRVATSKI:

Napokon utjelovljenje onog sto smo već i znali da je moguće ali smo čekali materijalizaciju argumenta u fizičkom obliku: Tesla sa original baterijom i 600000km na satu. Stigla nam ja Tesla od potpunog neznanca u punom povjerenju sa googla bez ikakvog nadzora na šlepi iz Beča, iako je još vozila ali limitiranim dosegom od 100km. Prvi put da smo osobno dokumentirali, da vi imate čast da je upoznate i da smo to mogli višestrukom analizom i provjerom potvrditi nakon izjave vlasnika da je baterija uistina netaknuta jer nas je zanimalo koji je to maksimalni prag zivotnog vjeka. Imali smo predozbu da prva baterija v1.5 drzi oko 400000km i da ju je potrebno servisirati, ali to je bilo vecinom kad je očekivani uzrok kvara prodor vlage ili oštećenje ožičenja. Ali ovo je izvan svih dosadasnjih skala jer baterija je bez greske hermetički zatvorena i bez prodora vlage po prvi put došla sa degradiranih 10 ćelija od ukupno 7104 ćelije, koje su zbog povećanog unutarnjeg otpora izazvale jaku oscilaciju “voltage relaxation” nakon mirovanja sto je ujedno “brick short” praznjenje jedne grupe od 74p a samim time aktiviralo i flag BMS_u029. Bez razvaljivanja kompletnog bloka 10 ćelija ce se mjenjati specijalnom extrakcijom i pripremiti za bench test na Solarnom UPS sustavu, a blok iz prethodne Tesle koja je prosla gladijator benchtest pribliznim kapacitetom od 200Ah ubaciti u ovaj battery pack tako da je zatvoren krug reciklaze/reparacije. Baterija je trenutno na kapacitetu od 67kWh ili 195Ah CAC što je oko 11% degradacija ili 89% SOH. Zanimljivo je i da je prvi motor koji smo vec spomenuli ranije P-Train MECH (Nije RMN) mjenjan tek na 500000km i samo zbog zujanja jednog lezaja je stavljen novi RMN u garanciji. Ponovno potvrda da je Teslin LDU vanzemaljski overkill samo da su zadrzali istu kvalitetu i na RMN modelu (Remanufacured). Tesla je uistinu kralj asfalta i kralj automotive revolucije, ometajući kompletan legacy mindset “umjerene kvalitete” i ostalih nametnutih kriterija legacy grupcija gdje je cilj napraviti vozilo da izdrzi garanciju pa da moras baciti i kupiti novo. Danas se proizvode sve komponente fosilca i testiraju do 180000km u simuliranom okruzenjima i ako izdrzi preko toga sustav je neprkiladan za komercijalnu prodaju jer “nemas vlasnika na pretplati”, dok sve dosad sto smo iz Tesle vidjeli analizirali probali popravljali rastavljali itd pokazuje apsolutnu opensource suprotnost. Ovdje je baterija nakon 9 godina i 600000km i dalje upotrebljiva, amortizirala je cijelo vozilo, nije bilo potrebno mjenjati cijelu kako to inače infodemičari tvrde i reparacija nije naučna fantastika. Dodatno smo uzeli u obzir da je na vozilu klima neispravna i da je mogući uzrok ostecenja par celija upravo nedostatak adekvatnog hladjenja. Trenutno po svim mjerilima ne postoji kvalitetniji powertrain na svijetu od njihovog i tu se bez kompromisa asevi već 10 godina i nemoljivo idu dalje, inoviraju i dižu skalu koju ne mogu pratiti ni najetaboliraniji proizvodjači. Slušamo već 10 godina mainstream infodemicare kako se baterija ne popravlja, kakao se cijela baca, kako je cijela skuplja od vozila (samo kod nissan leaf), kako je vjek samo 200000km, kako traje samo par godina… its medjutim kad smo sa održavanja dizel škarta prešli na EV svaki dan istrazivanja je bio prosvjetljenje. Nama je trebala materijalzirana potvrda, a vama tko je tražio vjesnik.

Letter to Tesla – Large Drive Unit RMN failure

Dear Tesla, we have previously sent you a private letter, but this one is being made public on behalf of all Tesla owners and we know why your RMN LDU Fails. And sorry TESLA, but this time we have improved LDU to more power and more range. While conducting the EVC refurbishment process, we have observed degraded quality on REMAN drive units in 25 different instances.

When the drive unit was initially designed in early 2012, Tesla incorporated a slightly different rotor, superior wire winding isolation, and a more efficient thermal conductive epoxy. The coolant seal on the rotor was also better, and the only issue encountered at that time was milling pitch noise, which some early Tesla supporters may remember, and it was solely due to a single ball bearing made by SKF in India.

Subsequently, Tesla made design changes to certain components, but the most significant aspect is the quality of the critical parts, namely the rotor shaft seal and the stator. In the older Large Drive Units (LDUs) labeled with “P-TRAIN,” if the seal failed and coolant entered the unit, it didn’t cause irreparable damage to the stator windings. However, the new LDUs that were replaced under warranty suffered permanent damage upon any coolant ingress. We conducted several probe tests on local cars (in HR, SLO, AT) to explore different drying processes, but unfortunately, they were unsuccessful. Some cars experienced immediate failures, while others faced failures at a later stage, as depicted in the attached picture, where one phase winding almost exploded and caused a short circuit with the vehicle chassis.


We were particularly concerned about the situation that arose regarding the availability of used or new drive units. Our concern stems from the need to prioritize sustainability and repairability. The new drive units, which are priced at approximately 7000€, were not being sold to third-party workshops, raising questions about the accessibility and availability of these crucial components for repairs and maintenance.

Subsequently, we received a few drive units from Germany that had experienced significant coolant ingress, resulting in stator damage beyond repair. The isolation of these units fell below the threshold of 4.9 Mohm per drive unit or 16 MOhm per disconnected phase terminal. This situation further highlighted the importance of maintaining proper coolant sealing and ensuring the integrity of the stator to prevent such irreparable damage.

Out of the units we examined thoroughly, we discovered three pieces that were in a state of complete defect, leaving us with no viable options for repair. Through extensive research and analysis, we documented various failures in both RMN and P-TRAIN LDUs. Our findings revealed that RMN LDUs had a maximum lifespan of approximately 100,000 kilometers, while the older P-TRAIN LDUs were capable of lasting over 300,000 kilometers. The primary cause of failure in the new RMN LDUs was predominantly attributed to coolant seal issues. Additionally, we identified instances where the Reman facility had utilized a coolant seal with a single lip (it should have 3), which resulted in even faster deterioration of the LDUs (within 30,000 kilometers).


This 1002713-00-D coolant seal was with only 1 lip, and it failed on almost NEW RMN LDU from Italy.

It is important to highlight the experience of our friend Hansjörg Gemmingen, who reported having eight drive unit replacements within a mileage of 2 million kilometers. Interestingly, the first drive unit managed to last nearly 800,000 kilometers. This revelation left us puzzled 2 years ago, prompting us to delve deeper into understanding the reasons behind these variations and what we could anticipate as we embarked on research and development for the remanufacturing and lifetime repair of these complex and heavy LDU units. We must acknowledge that this project poses significant challenges due to its intricate nature and the high expectations of durability and longevity.

Repairing 100 battery packs with complex issues may seem easier compared to achieving sustainable quality and high mileage in repairing LDUs. The intricate nature of LDUs and the need for long-lasting performance make the repair process more challenging. Ensuring the drive unit reaches new high mileage requires meticulous attention to detail, quality control, and continuous improvements in the repair and remanufacturing processes. It is a demanding task that requires expertise and a commitment to delivering sustainable and reliable results.

During the initial stages of our research and development process, we conducted extensive testing by repeatedly removing, disassembling, and reassembling the drive unit approximately 16 times. This rigorous testing allowed us to evaluate the performance, durability, and reliability of the drive unit under various conditions. Through these iterative steps, we aimed to refine our repair and remanufacturing techniques to ensure optimal functionality and longevity of the drive units. We failed to repair 3 drive units completely and complexity was beyond imagination, and we know other 3rd party workshops failing too, even Tesla is failing to refurbish them.

And now we assembled that to “holy grail” opeartion manual eTraining at EVC Academy and we redesigned coolant seal issue and we redesigned, optimised and tuned stator winding.

Our new coolant system cant ever ever again let coolant inside stator.
Our new stator cant ever ever get low isolation or overheating problems
Our new stator should increase range and power, decrease heating of the system
Our complete LDU assembly should last at least 700000km

This process is not just repairing the stator winding but improving it significantly and it costs pretty much as high as 3000€ with Tax included, just to repair on part.

What Owners should do and how to prevent all of this happening:
1- If you got RMN label on LDU, it will fail at 100K. You should make preventive service on stator/rotor side.
2-If you got P-Train label and you just got pitch noise comming from it, you should make preventive service on stator/rotor side or complete reman.
3-If your RMN LDU failed, consider that you are buying even lower quality LDU from Tesla.

What Tesla Inc. should do:

1-Change coolant seal supplier
2-Change stator reman supplier
3-Redesign coolant drain after seal
4-Change isolation at winding wire
5-Change thermal conductive epoxy

The Significance of Training and Proper Remanufacturing for BMS_U029: Beyond a Simple BMS Reset

Understanding the Risks and Importance of Resetting BMS_u029 and not repairing battery pack/blocks/cells.

We have been working on an issue related to BMS_u029 at EV CLINIC since March 2022 (https://evclinic.eu/2022/10/03/tesla-battery-repair-bms_u029/) , and we believe it’s crucial to share the findings.

The attached graphic displays four modules, two of which are from separate battery packs that came to us with a BMS_u029/Weak Short cell defect, and the other two from separate packs with a BMS_u018/Capacity Imbalance error.

These illustrations reveal something remarkable. Each red dot represents a cell that is experiencing self-discharge, occurring at a rapid rate of up to 20 mV per hour or more. When isolated from the rest of the brick, these cells discharge completely within 1 day, reaching 0 volts. (Typically, a healthy cell would discharge at a rate of <0.5 mV per day, which is a thousand times slower.)

Interestingly, the red dots are only present on the left side in the BMS_u029 column, while there are none on the right side in the BMS_u018 column. This is not a coincidence. It’s worth noting that these modules are not unique, as we have observed the exact same behavior across numerous modules.

What’s intriguing is that both the BMS_u029 and BMS_u018 modules exhibit noticeable capacity imbalances, with differences of up to 15 Ah or more in the case of the BMS_u018 modules, but it is usualy 6-10Ah. However, they manifest in two distinct failure modes.

In the case of the BMS_u018 modules, the cells themselves function fine with minimal self-discharge and can continue to operate, albeit with reduced capacity. These cells can even be repurposed or recycled for secondary use, just not in their current configuration as Model S battery modules.

On the other hand, each red dot in the BMS_u029 modules represents a potential runaway thermal event .

The top left module, apart from resembling chickenpox, is particularly alarming. Having this module in your pack would be highly undesirable, and resetting BMS errors on it is strongly not recommended if you didnt find and repair defect brick / cell.

Even the lower left module has one cell that poses a risk. If that cell shorts, it could trigger a potential runaway thermal event.

Furthermore, the BMS can identify even a single cell with the potential “weak short” and flag it as such. It latches the error to prevent inadvertent resetting or overlooking during unrelated firmware updates, system reboots, etc.

Additionally, the BMS can distinguish cells with potential weak shorts from worn and tired cells with capacity imbalances. It correctly recognizes the latter as being worn and tired, but not posing a significant threat. In fact, if the charge balance improves between cycles, the BMS will clear the BMS_u018 error and restore the battery’s normal operation, albeit at a diminished capacity.

In summary, Tesla’s BMS features are known to be exceptionally stringent when it comes to safety in battery systems. Understanding the problem referred to as “weak short” or “short to brick” took time, as it was a novel issue encountered initially by ourteam. For the BMS_u029 error, the rule is activated only when the battery remains idle for an extended period (approximately 8 hours or more) and exhibits a linear voltage drop in any of the 96S bricks. Activation triggers the w117 and u029 processes. This check is performed exclusively when the vehicle is not in use, and one out of the 76x 18650 cells in parallel becomes a consumer. The resulting damage is estimated to be in the range of €2-4. Initially, it was unclear which processor and memory stored the error flag/log and where the error transmission originated from.

It is important to say after all work and research, there is no easy way to address those issues without proper training and thats why we offere it to our partners and franchises.
https://evclinic.eu/evc-knowhow-academy/tesla/hv-battery/s-x-battery-master-training-operation-manual-2023612001/

Therefore, a couple of key takeaways emerge:

  1. Tesla is not bricking these packs inoperable with OTA software updates(it is not programmed defect like found in Mercedes vehicles) or by surreptitiously modifying thresholds during MCU upgrades. The BMS_u029 weak short conditions in the latest BMS firmware are genuine and implemented for your safety. We have observed this behavior in all the BMS_u029 packs we have received. We have numerous decommissioned modules with identical results. The BMS_u029 modules have cells experiencing self-discharge, while the BMS_u018 cells are worn and tired.

During the decommissioning process, we remove the collector plates, as shown in the attached photos, to isolate each cell. We then dismantle the module as necessary to repurpose any good cells for secondary use.

  1. It is extremely important not to reset these BMS_u029 errors without addressing the underlying issues with cells.

Honda Civic Hybrid 2009

Hybrids strike back with an invasion, while we complain about sponsored hybrid subsidized vacations. Every new hybrid that comes with Toyota’s “self-discharging” system in defect makes us more certain that our final review of them will definitely be the pinnacle soon, but the hint itself suggests that everything they release is just good marketing and that Toyota is the future Nokia. Every electrified product they have is a complete disappointment from a technical standpoint, and the BZ4X is a total failure of the powertrain system. Every battery system they have is quite cooked and degraded by 30-50% already at 100,000 km, but to avoid the error light turning on, they have implemented their own DTC OFF (colleagues know the terminology), meaning they have disabled the check engine light. It’s like when people deactivate the EGR on a Golf, Toyota has deactivated the fault code for battery failure. Then, with that same battery, people swear that they “never had to replace it” and that it’s still working fine. At 150,000-200,000 km, the battery is already burned with only 20% of its original state of health (SOH) capacity because the average cells, which started at 6.5Ah, are burned down to just 1Ah in total. In some cases, replacing some cells and reconditioning can keep it running for a while, but in other cases, all cells need to be replaced, which costs over 2,000-2,500 euros just for the material. The Honda Civic’s battery failed at 200k, and a new one costs 4,300 euros, plus the replacement at an authorized service. Granted, it also has years of use, but the fuel savings of 1.5 liters per 100 km with the presence of the battery amount to amortization of around 3,000-3,500 euros over 200k km, and that’s just one component of the hybrid system that drives around as additional weight for the sake of “savings.” The savings are only visible in the wallets of those who promote it.

HRVATKSI
Hybridi uzvraćaju invazijom a mi se kao bunimo na sponzorirani beneficirani godišnji odmor. Svaki novi hybrid koji dodje sa toyotinim “samošupljivim” sustavom u defektu sve smo sigurniji da će finalni osvrt na njih u skorije vrijeme definitivno biti vrhunac, ali sam nagovještaj se da naslutiti da je sve sto oni izbace samo dobar marketing i da je Toyota buduća Nokija. Svaki elektrificirani proizvod im je sa tehičke strane potpuno razočarenje, BZ4X im je totalni promasaj powertrain sustava. Svaki baterijski sustav im je poprilično skuhan i degradiran 30-50% vec na 100000km, ali kako se nebi greška palila oni su sami sebi implementirali DTC OFF (kolege znaju terminologiju) tj isključili paljenje checkengine lampice. Kao kad ekipa na Golfu deaktivira EGR, tako je toyota deaktvirala paljenje greske na kvar baterije. Onda se tom istom baterijom ekipa kune kako je “nikad nije mjenjala” i kako je još ispravna. Na 150000-200000km baterija je spaljena vec na 20% SOH kapaciteta jer su srednje celije sa pocetnih 6.5Ah spaljene na ukupno 1Ah. U nekim slucajevima izmjena nekih ćelija i rekondicioniranje moze drzati neko vrijeme, ali u nekim slucajeva moraju se mjenjati sve celije što samo u materijalu izadje preko 2000-2500 eura. Hondi Civic je baterija zaribala vec na 200k i nova dodje 4300€ plus izmjena u ovlaštenom servisu. Doduše ima i godina ali ušteda goriva od 1.5l postojanjem baterije na 100km je amortizacija oko 3000-3500€ na 200k km a to je samo jedna komponenta hybridnog sustava koja se voza okolo kao dodatna masa radi “uštede”. Ušteda je vidljiva samo u novčanicima onih koji to odražavaju.

Renault Zoe – R240 milling sound

R240 is a newer generation drivetrain that many of us have been eagerly awaiting outside of the warranty period to see what fails on the air-cooled electric motor and the transmission differential. Two years ago, we received the first call from Varaždin regarding an EQ 453 Čmart, reporting that the motor had started milling and that the warranty claim was denied. The price of a new motor with replacement was around €4000, with only 90,000 km driven. At first, this seemed unusual for such a low mileage, but on the other hand, it wasn’t surprising considering it’s a French factory defect powertrain from the Renault Cléon factory, as if it was designed by some straight pipe, turbo diesel, DPF off, EGR off, EV-hating engineer, where not a single component was intended to be serviced or repaired (apparently, they haven’t heard of the Balkans). They even managed to fit brushes on the rotor of the three-phase motor for exciting the windings, so that there’s something to wear out. This is probably the only electric drivetrain on the planet that is both the worst and the most expensive.

For any operation on the drivetrain, the entire assembly must be removed from the vehicle. This is the first time we’re repairing the buzzing and turning defect in the drivetrain, and the restoration process is relatively straightforward. The procurement of parts, bearings, seals, and other materials is a slightly more complicated part, as one particular bearing on the jacksaft extension in the gearbox is produced by only one company in France. Fortunately, Lageros had one in stock specifically for this project.

In addition to the mentioned Smart from Varaždin and this Zoe from Slovenia, we have received several inquiries from Germany, Slovenia, and Norway on similar car mileage arround 100000km, but we haven’t had the opportunity to work on one yet. This particular case was successfully resolved at 1/4 of the cost of an authorized service at 118,000 km. The largest expense was the time required for disassembly and reassembly, followed by the cost of parts. In some cases, if there is turning and material wear in the differential, it may result in the wearing of the differential gears, where even after the complete drivetrain repair, a slight buzzing noise may remain, which is transmitted into the cabin. Gear replacement is not possible as they are not available, but in such cases, the entire restoration is still usable for the next 100,000 km until the next restoration.

It is strongly recommended to address any buzzing or turning sounds from the electric drivetrain immediately to prevent further damage.

HRVATSKI:

Renault Zoe – R240 pogon novije generacije koji već dugo iščekujemo izvan garancije da vidimo što to odlazi na zračno hladjenom elektromotoru a što na prijenosnom diferencijalu. Prije 2 godine prvi poziv smo dobili iz Varaždina za EQ 453 Čmart da je motor počeo zujati i da nisu prihvatili garanciju a cijena novog motora sa izmjenom je bila oko 4000€ na prijedjenih 90000km. Sto je na prvu čudno za tako malan broj kilometara ali na drugu i nije čudno jer to je francuski škart pogon iz Renault Cléon tvornice kojeg kao da je dizajnirao neki strejt pajp turbo dizel dpfoff egroff EV hejter inženjer gdje niti jedna komponenta nije osmišljena da se servisira i popravlja (valjda nisu čuli za balkan) gdje su na trofazni motor uspjeli uglaviti i četkice na rotoru za pobudu namotaja da se ima šta trošiti. Ovo je vjerovatno jedini električni pogon na kugli zemaljskoj koji najgori i najskuplji. Za svaku operaciju na pogonu, kompletan pogon se mora vaditi vani iz vozila. Na ovom prvi put repariramo defekt zujanja i tokarenja u pogonu i što se tiče same restaturacije proces je poprilično jednostavan. Nabava dijelova, lezajeva, brtvi i ostalog materijala je malo kompliciraniji dio jer na jacksaft produžetku rotora u mjenjaču jedan ležaj ne proizvodi nitko osim jedne firme u Francuskoj. Imali smo sreću da je Lageros imao na stanju jedan baš za ovaj projekat. Osim ovog spomenutog Smarta iz Varaždina i ovog Zoe iz Slovenije, imali smo nekoliko upita iz Njemačke, Slovenije, Norveške ali nismo imali priliku da i radimo na jednom. Ovaj je uspješno riješen za 1/4 troška ovlaštenog servisa na 118000km, najveci trosak je vrijeme demontaže i montaže a zatim trošak dijelova. U nekim slučajevima ako dodje do tokarenja i trosenja materijala u diferencijala, može se desiti da dodje do trošenja zubi diferencijala gdje i nakon reparacije cijelog pogona i dalje ostane manji zvuk zujanja zubi koji se prenosi u kabinu. Izmjena zubčanika nije moguća jer ih nema u nabavi, ali u tom slucaju kompletne restauracije cak iako ostane zujanje zubčanika cijeli sustav je realno upotrebljiv narednih 100000km do sledece restauracije. Svakako je preporuka da se svaki zvuk zujanja i tokarenja iz električnog pogona otkloni odmah kako nebi doslo do veće štete.

SLOVENSKI:


Renault Zoe – R240 je pogon nove generacije, ki smo ga že dolgo čakali, a je zunaj garancije, da vidimo, kaj odpove na zračno hlajenem elektromotorju in kaj na prenosnem diferencialu. Pred 2 letoma smo prejeli prvi klic iz Varaždina za EQ 453 Čmart, da se je motor začel ropotati, vendar garancije niso sprejeli, cena novega motorja z zamenjavo pa je bila približno 4000 € pri prevoženih 90000 km. Na prvi pogled je to nenavadno za tako majhno število prevoženih kilometrov, vendar pa na drugi strani tudi ni presenetljivo, saj je to francoski slabo narejen pogon iz Renaultove tovarne Cléon, ki ga je oblikoval nek strejt pajp turbo dizel dpfoff egroff EV sovražni inženir, pri čemer nobena komponenta ni bila zasnovana za servisiranje in popravilo (verjetno niso slišali za Balkan), kjer so uspeli v trifazni motor vgraditi še ščetke na rotorju za vzbujevalno navijanje, da se ima kaj za obrabiti. To je verjetno edini električni pogon na svetu, ki je najslabši in najdražji. Za vsak poseg na pogonu je treba celoten pogon odstraniti iz vozila. Tokrat prvič popravljamo okvaro ropotanja in vibriranja pogona, kar se tiče same restavracije, je postopek precej preprost. Težje je pridobiti dele, ležaje, tesnila in drugi material, ker nihče ne proizvaja enega ležaja, ki ga potrebujemo za ta projekt, razen enega podjetja v Franciji. Imeli smo srečo, da je Lageros imel na zalogi enega ravno za ta projekt. Poleg omenjenega Smarta iz Varaždina in tega Zoeja iz Slovenije smo prejeli nekaj povpraševanj iz Nemčije, Slovenije, Norveške, vendar nismo imeli priložnosti delati na nobenem od njih. Ta primer smo uspešno rešili za 1/4 stroška pooblaščenega servisa pri 118000 km, največji strošek je čas demontaže in montaže, nato pa strošek delov. V nekaterih primerih, če pride do vibriranja in obrabe materiala v diferencialu, se lahko zgodi, da pride do obrabe zobnikov diferenciala, pri čemer kljub popravilu celotnega pogona še vedno ostane manjši zvok ropotanja zobnikov, ki se prenaša v kabino. Zamenjava zobnikov ni mogoča, saj jih ni na voljo, vendar je v tem primeru celoten sistem dejansko uporaben še naslednjih 100000 km do naslednje restavracije. Vsekakor je priporočljivo, da se vsak zvok ropotanja in vibriranja v električnem pogonu odpravi takoj, da ne pride do večje škode.

Tesla S/X PTC Cabin Heater

A ceramic heater that warms the vehicle during winter, mostly used in older EVs while newer ones have a more efficient heat pump system. This heater operates at a maximum power of 2.5-3.5 kW and consumes an average of around 1 kW for maintenance while stationary, which means that during winter, an EV with a 70 kWh battery could run the heater and heat the cabin for a maximum of 70 hours, although in practice it’s around 48 hours. The heater consists of 6 IGBTs that, through gate drivers, supply 400V to the ceramic heater, which blows air through it and heats the cabin. Since IGBTs, like any other chip, have a limited lifespan, especially under extreme stress, they can simply fail after 4-5 years. Sometimes a short circuit to the chassis causes insulation breakdown in the HV system, and other times the fuse in the distribution box burns out (which requires breaking your hand in three places and losing a set of tools to replace it). One of the simpler repairs, if the components are available and genuine (not AliExpress clones). In Tesla service, this part is actually surprisingly inexpensive, around €750 when new, although Tesla has the cheapest parts compared to the global competition. For example, the PTC heater in a Mercedes Smart costs over €2000. Even some fossil fuel-powered vehicles have 12V Aux PTC heaters, like VW Audi TDI.

HRVATSKI:

Keramicki grijač koji zimi grije vozilo, većinom korišten na starijim EV dok novi imaju efikasniju dizalicu topline (heat pump system). Ovaj radi max na 2.5-3.5kw snage, dok na odrzavanje trosi u prosjeku u mjestu oko 1kw sto znaci da bi zimi EV od 70kwh baterijom mogao stajati u mjestu i grijati kabinu max 70 sati dok u praksi je to oko 48 sati. Grijač ima 6 IGBT-a koji preko gate drivera otvaraju 400V na keramicki grijac dok zrak upuhuje kroz njega i grije kabinu. S obzirom da IGBT ima broj radnih sati kao i svaki čip, pogotovo ovaj koji je pod ekstremnim stresom, jednostavno otkaže u odredjenom momentu nakon 4-5 godina. Nekad kratak spoj na sasiju napravi pa imaš proboj HV izolacije a nekad izgori i osigurač u razvodnoj kutiji (kojeg da bi zamjenuo moras slomiti ruku na 3 mjesta i izgubiti set gedori). Jedan od jednostavnijih reparacija ako su komponente dobavljive i original ( ne aliexpress cloneri ) . Dio je inače smješno jeftin u Tesla servisu i nov, cca 750€, mada Tesla ima najeftinije sve dijelove od cijele globalne konkurencije. Recimo Mercedes Smart PTC heater košta preko 2000€. Čak i neki fosilci imaju 12V PTC Heater kao VW Audi TDI.

Opel Ampera 2013 – Neglected omission on coolant sensor

An electric vehicle with a built-in Range Extender or hybrid system, also known as the REX (Range Extender) system. Trolls mock it because it involves both electricity and an petrol generator. Although we’ve been “loving” hybrids for a long time and praising them every day because we live off sponsors (like most drivers and journalists, praising everything that’s flawed), we have to admit that the REX system is the only one that makes sense. You don’t have a gearbox, you don’t have a clutch, or 10 other unnecessary transmission components because you already have an electric drive; you just add a small 1.4-liter gasoline engine to work as a generator and recharge the battery only when necessary or when more power is needed. Opel, or rather GM, did this better than any “Made in EU” hybrid junk with a range of about 70 km. But GM, like any legacy manufacturer, has to complicate things, like the situation with the well-known coolant level sensor problem, which has two submerged electrodes and measures resistance through the glycol (24kOhm). The P0AA6 error is a generic insulation breakdown error that causes the system to deactivate charging on Type 1, which is not the primary problem (the car still drives) because it seems that the system checks if there is an insulation breakdown in the HV system through that sensor. No one predicted that the sensor would be faulty and that it would trigger a false positive insulation breakdown error. But that’s not the whole issue; it seems that consecutive insulation checks through that sensor activate either a bug or a feature, the P1FFF error, which permanently damages the firmware in the HPCM2 module, where the error remains permanently locked. You have an error indicating an insulation problem, and the system occasionally shows 0 and 240 kOhm in the parameters, which obviously confirms that there is something wrong with the wiring or component. So, we measure everything one by one for 15 working hours, almost even removing and opening the battery because we realized that it seems normal for it to throw 300V to the chassis on the service fuse. After a few days of measurement exorcism, we fail to clear the error and resolve the charging issue. Even parallel checks with the same functioning vehicle don’t help us figure out why. Then, lost in the depths of the internet, we found a recommendation to reprogram the HPCM2 module using the original GDS2 tis2web tool. And unbelievably, programming solved the problem that we’ve been struggling with for days. It’s a classic story well known to mechanic colleagues, where the carelessness of legacy manufacturers, who poorly solved the software, causes the module to throw an error that leads in the wrong direction. You end up replacing half the parts just to maybe figure out where the problem might be. You spend hours and hundreds of euros, and then some Socrates would say that the mechanic is not good or doesn’t know what he’s doing. There are more and more of these phantom errors and problems in diesel/benzin EU vehicles, with some cars having over 20 errors that lead to misguided repairs.

Opel Ampera 2013 – Električno vozilo sa ugradjenim Agregatom ili hybrid a neki ga zovu REX sustav (Range extender) a trolovi sline jer se spominje struja i agregat. Iako “volimo” hybride odmilja i hvalimo ih svaki dan jer od sponzora zivimo (kao vecina automobilista i novinara, hvalis sve sto nevalja) moramo priznati da REX sustav jedini ima smisla, nemas mjenjaca, nemas lamele i 10 drugih nepotrebnih komponenti prijenosa jer vec imas elektropogon, samo stavis 1.4 mali benzinac da radi kao agregat i dopunjuje bateriju samo ako mora ili ako fali snage. Opel, tj GM je ovo bolje napravio nego bilo što od Made in EU hybrid škarta, sa dometom od oko 70km. Ali GM kao i svaki legacy mora zakomplicirati nešto kao situaciju sa vrlo poznatim problemom senzora nivoa antifriza u boci, koji ima utopljene dviie elektrode i mjeri otpor kroz glikol. Greška P0AA6 je genericka greska direktnog proboja izolacije zbog koje sustav deaktivira punjenje na Type1 što ne primarni problem (auto vozi), jer izgleda preko tog senzora sustav provjerava je li probija i HV sustav. Nitko nije predvidio da će senzor biti neispravan i da ce to opaliti false positive gresku proboja izolacije. Ali nije sav vrag u tome, izgleda uzastopne provjere izolacije preko tog senzora aktiviraju ili bug ili feature P1FFF grešku koja trajno osteti firmware u HPCM2 modulu gdje greška ostaje zaključana trajno. Imaš grešku koja kaže da je problem izolacije, cak sustav u parametrima pokazuje povremeno 0 i 240kOhm, sto naravno potvrdi da nesto ne valja na ožičenju ili komponenti pa onda kao mi sve redom mjerite 15 radnih sati, skoro smo i bateriju skidali i otvorili jer ona (skuzili da je to izgleda normalno) na service fuse baca na sasiju 300V.

Nakon par dana egzorcizma mjerenja ne uspjevamo izbrisati grešku i ne uspjevamo riješiti punjenje i paralelne provjere sa istim ispravnim drugim vozilom ne uspjevamo skužiti zašto, da bi u bespuću interneta našli preporuku da naprogramiramo HPCM2 modul original GDS2 tis2web alatom. I nevjerovatno, programiranje riješilo problem oko kojeg se vrtimo danima. Klasična priča vrlo poznata kolegama mehaničarima gdje šlampavost legacy proizvodjaca koji su nakaradno riješili software, modul izbaci gresku koja odvede u pogrešnom smjeru gdje moras mjenjati pola dijelova da bi skuzio uopce gdje bi mozda mogao biti problem, potrosis sati i stotine eura da bi jos neki sokrat rekao kako majstor nevalja ili nezna. Takvih fantomskih gresaka i problema na dizel/benzin EU vozilima je sve više i više, neka vozila imaju i preko 20 gresaka koje vode u pogresnom smjeru reparaciju.
