Mercedes EQV – “May the defect be with you”


The pain of the whole work experience has so far shown that it does not matter what type of drive is under the hood of the three-pointed star for the last 10-12 years. It doesn’t matter if it’s diesel or electric, they don’t know how to make one without several serial defects “in the warranty” that you “don’t have the right to”. A very well-known courier service visibly disappointed by the “electrification” that has several EQV vehicles in the fleet and with declined warranty on 2 years for electric motor, one of them has already broken down, i.e. the electric motor decided to rob the owner for €7,500 at 28,000 km. After a hard reset of the system, we managed to get the electric motor to drive, but immediately after a small load or pressing the accelerator pedal harder, it threw the “Mercedes anomaly” error (we’ve known that for a long time) and deactivated again permanently. We mostly knew that it was definitely an electric motor and that the diagnostics of the authorized service coincided. Dismantling of electric motor is a process of several hours, it goes complete with a whole kind of steel cage and all together it weighs over 250 kilos for 80KW power. Due to its size, the electric motor does not give off any impression of power, it is twice smaller than all Tesla motors seen so far, and it is located on a 3200 kg vehicle. Right from the start, it is clear that the engine is underdesigned for the EQV and its mass. After opening the drive unit manufactured by ZF allegedly in Serbia, antifreeze and other fluids immediately leaked from the stator, where it should not be. The rotor was cooled with antifreeze using the method that Tesla used on the first Model S RWD in 2012, and it seems that glycol was released into the stator, where, in addition, due to cracking of the insulation on the windings due to thermal expansion, there was also a short circuit and burning of one part of the winding of one phase. Fortunately, the inverter was not damaged. We almost gave up there, but considering that this smelled like a new crap sponsorship and a possible repetition of the failure with other vehicles under the EQ label, we invested 3 weeks of research and analysis. The Mercedes EV killer, believe it or not, is the parking lock mechanism that they built into the electric motor itself. Every time you stop and press parking on the handle, and the wheels turn even the smallest millimeter, then the rotor turns 9 times faster, while at the same time the parking lock system pushes the lever and violently stops the rotor. The rotor breaks the first bearing in the differential on the lever and then breaks the second one at the other end of the rotor where the lamella/seal for the coolant is. A system designed in a cascade defect manner. First, why does it even allow the electromagnetic solenoid to be activated to push the pulley into the rotor if the wheels are still spinning? They have several input sensors to prevent this, but they have not implemented any. Ok, now some fb expert will say, so what does it matter, there are also Zoe and Smart and some other vehicles… yes, but this is a 3.5-ton vehicle with an engine that would barely work on an eGolf. There are far better solutions and rules, the first rule is “dont touch the f***ing rotor” and implement electric parking brake. If you are looking for an EV with the longest electric motor life, look without the PARKING LOCK system and with ELEC PARKING MANUAL.One of the ultra positive things that electrification brings is that, in addition to being able to consume “domestic electricity”, we also enrich the local economy and revive old local crafts, far from the monopoly of the fossil industry. We performed the complete restoration, analysis and procurement of parts within a radius of 2 kilometers from the workshop.
And those of you who already have this stupidity in operation, stop the vehicle, pull the manual and then put it in the parking lot. In OEM MB Workshop they declined warranty on electric motor because the warranty is only 2 years for it.

Mercedes EQV – “May the defect be with you”
Muka cijelokupnog iskustva je do sada pokazala da nije bitno koja je vrsta pogona ispod haube trokrake zvijezde zadnjih 10-12 godina. Nije više bitno je li dizel ili na struju, ne znaju napraviti niti jedan da nema nekoliko serijskih grešaka “u garanciji” na koju “nemaš pravo”. Vrlo poznata kurirska služba vidno razočarana “elektrifikacijom” koji u floti imaju nekoliko EQV vozila, jedno se već raspalo, tj. elektromotor je na 28000km odlučio opljačkati vlasnika za 7500€. Nakon hard reseta sustava uspjeli smo pokrenuti pogon da vozi još jednom, ali je odmah nakon malog opterecenja ili jaceg stiskanja papučice akceleracije izbacio grešku “mercedes anomalia” (to znamo vec odavno) i ponovno se trajno deaktivirao. Mi smo uglavnom znali da je definitivno elektromotor i da se dijagnostika ovlaštenog servisa poklapa. Demontaža elek. motora je proces od nekoliko sati, ide kompletno sa cijelim nekakvim kavezom od čelika i sve skupa je teško preko 250 kila. Elektromotor svojom velicinom ne odiše nekakvim dojmom snage, duplo manji je od svih dosad Teslinih vidjenih motora a nalazi se na vozilu od 3200kg. Odmah na prvu je jasno da je motor poddizajniran za EQV i njegovu masu. Nakon otvaranja pogona kojeg proizvodi ZF navodno u Srbiji odmah su antifriz i ostale tekucine izcurile iz statora, gdje nebi smjelo biti. Rotor je hladjen antifrizom metodom koju je Tesla koristila na prvim Model S RWD iz 2012 i tu je izgleda pustio glikol u stator gdje je dodatno zbog pucanja izolacije na namotajima zbog termičkog istezanja takodjer došlo do kratkog spoja i izgaranja jednog dijela namotaja jedne faze. Sva sreća da nije i inverter oštećen. Tu smo skoro odustali, ali s ozbirom da je ovo mirisalo na novo sponzorstvo i moguće ponavljanje kvara ostalim vozilima pod EQ oznakom, investirali smo 3 tjedna istraživanja i analize. Mercedes EV killer je vjerovali ili ne, parking lock mehanizam kojeg su ugradili u sam elektromotor. Svaki put kad stajete i pritisnete parking na ručici, a kotači se okreću i minimalni milimetar, tad se rotor još okreće 9 puta većom brzinom dok istovremeno sustav parking lock-a gura polugu i nasilno zaustavlja rotor. Rotor razbija na polugu prvi lezaj u diferencijalu a zatim razbija i drugu na drugom kraju rotora gdje je lamela/brtva za rashladnu tekićunu. Sustav dizajniran kaskadno nakaradno. Prvo zasto dopušta uopce aktivaciju elektromagnetnog solenoida da gura pulugu u rotor ako se kotači još vrte? Nekoliko input senzora imaju da to spriječe ali nisu implementirali niti jedan. Ok sad će neki fb expert reći pa šta ima veze, ima i Zoe i Smart i neka druga vozila… da ali ovo je vozilo od 3.5 tone na motoru koji bi jedva radio i na eGolfu. Postoje daleko bolja riješenja i pravila, prvo pravilo je “dont touch f***ing rotor” i impementiraj električnu parking ručnu. Elektromotor smo pustili lokalnoj firmi da analizira stator i da ga proba ponovno namotati po specifikacijama originala i uspjeli su od prvi put ali su pogresno rotirali dvije faze pa je motor vozio kontra. To smo ručno mi vratili na pravilno mjesto i sve je proradilo u originalu ali svaki puta treba vaditi kompletan prednji kavez, poluosovine itd… Jedna od ultra pozitivnih stvari koju elektrifikacija donosi je da osim što možeš trošiti “domaću struju” takodjer obogaćujemo lokalnu privredu i oživljavamo stare lokalne zanate, daleko od monopula fosilne industrije. Mi smo kompletnu restauraciju, analizu i nabavu dijelova obavili u krugu 2 kilometra od radione. Ako tražite EV sa najdužim vijekom elektro motora, tražite bez PARKING LOCK sustava i sa ELEK PARKIRNOM RUČNOM.
A vi koji već imate tu glupost u pogonu, zaustavite vozilo, povuci rucnu pa onda ubaci u parking.

Electric EQV – Grand theft defect

If you are interested in to the “how and why EU Car industry failed”, read on. Sometimes thieves had masks, sometimes without a mask they had the middle name “politician”, and today the robbery is organized by the EU car industry with programmed faults and invented defects (dpf, egr, scr, addblue) and the owner of the same becomes an donkey when the “subscriptions” start. Every “threstar” diesel – gasoline – electric – hybrid since 2001 has been produced with programmed faults, both mechanical and electronic. Beginning was from old SBC abs pump on W211 which had BRAKE COUNTER if it hits 0 from 200000, SBC goes into defect and completely healty SBC must be changed for 4000 euro. Thus, every subsequent revision and model of the vehicle had an exponential growth of programmed failures, where today you have the steering column electronics SCCM, Dualclutch transmission, ESL steering wheel, N1 N2 sensor 7G/9G transmission when it counts down, etc., etc.. The problem is not that the “herd” likes these costs paying for programmed breakdowns of diesel/gasoline, the problem is that THEY have now added another zero to the invoice of repair offer for electric models. This is 3rd inquirie this week from 3 different owners, that in a very minor contact with another object on the road they lost power and that their battery was deactivated and not a single airbag went off. Now, in addition to painting the bumper, you also have to change the battery because OEM has programmed it so that you change a completely healty battery on which the OTP (one time programming / readonly) error was activated. You feel the sourness when you find out that the error was designed with one purpose and that there was no service access or so-called “backdoor access” via the seedkey key to delete the error via OBD through the developer mode “DTS Monaco” and similar methods. They created an error code for themselves that even they cannot delete with the Developer access tools. So there remains only invasive BDM directly on the processor. This is controversial and ethically incorrect on several levels and quite absurd that such big failures are not pushed to the media to protect the consumer, but they are just waiting for the news when the steering wheel will fall off only 1 Tesla or some other clickbait shitnews. Here it is disputed too that the insurance companies also suffer the damage of epic disputes because battery changes are being “ironed” completely unfounded, which will lead to an exponential increase in basic and casco policies, but media will use those “fake news” to “blave EV industry” and not the EU scrap with programmed defectes. The battery for the EQV is €75,000 including delivery and installation, the warranty is rejected because this error is not included in the warranty after any damage to the vehicle. A colleague in Kiev who worked on the project to enable the vehicle, from HW pinout to software readout and other assistance, we managed to remove the error “P0CA7” which deactivated, disabled and sent for destruction a completely working 100kWh battery. The design of the battery is very similar to the Stellantis platform with eJumpy eVivaro, etc., even the BMS controller used 90% of the same components, so the entire platform was borrowed from the supplier and as hardware is not a OEM product, but the entire software is their signature. We already have the same programmed failure on EQC EQB EQA eSprinter, all hybrid series. It is recommended that they avoid absolutely all series and models of MB powertraings, because soon no one will be able to help you, we are raising the prices of repairs for this EV by 400% for demotivational purposes.

HRVATSKI:

Električni EQV – ako vas zanima kako je i zašto, propala EU automobilska industrija nastavi čitati. Nekad su lopovi imali maske, nekad bez maske su imali srednje ime “političar” a danas te opljačka organizirana automobilska EU industrija sa programiranim kvarovima i izmisljenim defektima (dpf,egr,scr,addblue) a vlasnik istog postaje magarac kad krenu “pretplate”. Svaki auto trokrake dizel benzin struja hybrid jos od 2001 se proizvode sa programirani kvarovima, sto mehanickim sto elektronskim, prvi brojači koliko puta pristisnete kočnicu kad odbroji 200000 pritisaka tad vam se softwerski deaktivira SBC sofisticirana elektronska abs pumpa, morate po novu od 4000€ (iako je i stara jos ispravna). Tako je svaka sledeca revizija i model vozila imala eksponencijalni rast programiranih kvarova gdje danas imate da vam se odjednom izbrise elektronika stupa volana SCCM, Dualclutch mjenjac, ESL volana, N1 N2 senzor 7G mjenjaca kad odbroji itd itd. Problem nije sto krdo voli te troskove i placati programirane kvarova prdilica dizel/benzin, problem je sto su sad svabe dodale jos jednu nulu na ponudu za popravak na elektricnim modelima. Ovo je 3 upit ovaj tjedan 3 razlicita vlasnika, da su u sasvim minornom dodiru sa drugim predmetom na cesti ostali bez pogona i da im se baterija deaktivirala a niti jedan airbag nije ispucao. Sad osim farbanja branika , morate mjenjati i bateriju jer je proizvodjac tako naprogramirao da mjenjate sasvim ispravnu bateriju na kojoj je se aktivirala OTP greška. E sad onaj najkiseliji dio “pa sta ima veze” to se samo resetira original dijagnostikom. Kiseliost osjetiš kad skužiš da je greška osmisljena sa jednom svrhom i da uopce nije ostavljen service access ili takozvani “backdoor access” putem seedkey kljuca da se i kroz developer mode “DTS Monaco” i slicnim metodama izbrise greska putem OBD. Oni su sami sebi napravili kod greske koji ni oni ne mogu sa Developer access alatima izbrisati. Znaci ostaje samo invazivna BDM direktno na procesor. Ovo je sporno i etički neispravno na nekoliko nivoa i poprilicno apsurdno da se ovako veliki propusti ne guraju u medije da se potrosac zastiti, vec se samo cekaju vijesti kad ce na Tesli otpasti volan ili neki drugi clickbait shitnews. Ovdje je sporno sto i kasko osiguranja trpe stetu epskih razmijera jer se “peglaju” izmjene baterija totalno neosnovano, sto ce dovesti do eksponencijalnog porasta osnovnih i kasko polica, pa ce se opet peglati fakenews kako je “elektrifikacija kriva” a ne EU skart sa programiranim kvarovima. Baterija za EQV je 75000€ sa dostavom i ugradnjom, garancija je odbijena jer ta greska nakon bilo kakvog ostecenja vozila ne ulazi u garanciju. Kolega u Kievu koji je radio na projektu da osposobi vozilo, od HW pinout do software readout i ostale asistencije uspjeli smo maknuti grešku “P0CA7” koja je deaktivirala, onesposobila i poslala na unistenje kompletno ispravnu bateriju od 100kWh. Baterija je dizajnom veoma slicna Stellantis platformi sa eJumpya eVivaro itd, cak je BMS kontroler koristio 90% istih komponenti, tako da je cijela platforma posudjena od suppliera i kao hardware nije proizvod trokrake zvijezde, ali je cijeli software u njiihovom potpisu. Isti programirani kvar smo vec nasi na EQC EQB EQA eSprinter , sve serije hybrida. Preporuka je da izbjegavare apsolutno sve serije i modele pogona na MB jer nece vam uskoro niko moci pomoci, cijene reparacija za trokraku zvijezdu dizemo za 400% u demotivacijske svrhe.

Electric EQC programmed defect

AVOID this EV – we received second inquiry to repair EQC in 3 weeks. Another customer is stuck with 35000€ programmed defect and nobody is able to help?! If there anyone who want to invest, buy me EQC and i will randomly trigger moneystealing error then we investigate how this BMSGate is devastating automaker strategy.

Error: P1D2800 (Programmed counter reached 0 value)

OEM Repair: 35000€

EVC repair – no solution

EQ series – Programmed defect which will cost you 40000€ outside warranty. We researched MB for last 15 years and first programmed defects and error counters were implemented in SBC pump, later in ELV EIS 7G VGS4 and lately in almost all components. First battery on hybrids and Smart ED were new victims of same policy, but we were hopping they changed it and removed it from new EQC and other EQ models, but we were wrong. We heard about few cases with some nonremovable BMS error flags but never direct contact with “victim”, this is first case and confirmation of our nightmare. EQC has programmed error counter, if it triggers error, you would probably need to change completely healthy battery (like Smart451 453, hybrids 212 221 205 222) which costs around 40000€. This way of doing business is not sustainable. We advise to all of our followers, your friends and family to avoid buying new or used EQC, and probably EQS EQA EQB.

Programirani kvar koji će vas koštati 40.000 € izvan jamstva. Istražujemo MB zadnjih 15 godina i prvi programirani defekti i brojači grešaka implementirani su u SBC pumpu, kasnije u ELV EIS 7G VGS4 a u posljednje vrijeme u gotovo sve komponente. Prve baterija na hibridima i Smart ED bili su nove žrtve iste politike, ali nadali smo se da su je promijenili i uklonili iz novih EQC i drugih EQ modela, no prevarili smo se. Čuli smo za nekoliko slučajeva s nekim neuklonjivim FLAG error greskama BMS-a, ali bez izravnog kontakta sa “žrtvom”, ovo je prvi slučaj i potvrda naše noćne more. EQC ima programirani brojač grešaka, ako aktivira grešku, vjerojatno bi trebali promijeniti potpuno zdravu bateriju (kao što je Smart451 453, hibridi 212 221 205 222) koja košta oko 40.000 eura. Ovakav način poslovanja nije održiv. Savjetujemo svim našim pratiteljima, vašim prijateljima i obitelji da izbjegavaju kupnju novog ili rabljenog EQC, a vjerojatno i EQS EQA EQB. A ako imate nekog koga mrzite (punicu) nagovorite je da kupi EQC a mi ćemo u pola cijene popraviti programirani kvar. Pritisak jednog ENTER na tastaturi košta 20000€.

Preporuka IZBJEGAVAJTE EQ SERIJU
