Of course, it can, depending on the severity of the damage. Recently, we mentioned how important it is to inspect and perform a “reseal” on the battery after 6-7 years. Here, the original battery from a 2015 Tesla Model S P85D had water ingress directly into the high-voltage part where the pyrofuse is located. The vehicle shut down immediately and was brought from Austria through our partner channels for vehicle towing service. Tesla offered a complete new battery for around €20,000 (cheaper than a new CRT Audi 3.0 TDI diesel engine), even though the procedure could have been simple for them if they had removed and inspected it; they probably would have offered a Reseal, as we did. We won’t even use the word “repair” here because that procedure wasn’t even performed. We replaced the fuse cover, installed a new pyrofuse, new valves, and performed a full EVC reseal (business secret), so this battery, with 250k km on it, is ready for at least another 300k km. This is not full battery remanufacturing because this job doesnt include full battery opening. We do no open any original seals on battery lid. For other defects like BMS_u018, f107 f098 f097 u025 or most notorious BMS_u029 it is necessary to make RESEAL + FULL REMANUFACTURING where we need between 50-90 labor hours.

Može li se Tesla baterija reparirati za 1000€? Naravno da može i ovisi o težini kvara. Nedavno smo spominjali kaoliko je važno nakon 6-7 godina pregledati, ispitati i napraviti “reseal” baterije. Ovdje je originalna baterija iz 2015 sa Tesla Model S P85D imala prodor vode direktno u visokonaponski dio gdje se nalazi pyrofuse. Vozilo je se ugasilo odmah i doveženo je iz Austrije putem naših partner kanala za dovoz vozila. Tesla je u ponudi tražila kompletno novu bateriju nekih 20000€ (jeftinije od novog CRT Audi 3.0 TDI dizel motora) iako je zahvat i njima mogao biti jednostavan da su je skinuli i pregledali, vjerovatno bi ponudili Reseal kao i mi. Ovdje “reparacija” riječ necemo ni koristiti, jer taj zahvat nije ni napravljen. Ovdje smo izmjenili poklopac osiguraca, stavljen je novi pyrofuse, novi ventili i napravljen je puni EVC reseal (poslovna tajna) tako da je ova baterija da sa predjenih 250k km spremna za sledećih bar 300k km.

But after 6-7 years a model S would still be under warranty wouldn’t it
Yes, Tesla should not pretedent that “no maintanance” is correct statement. They should reseal battery in warranty, and they did it on some 30% of model s, but randomly and not on all.
I think I might have a similar case now. Two months ago my Model S 2015 showed the errors BMS_w123 and BMS_f123 and said “restart maybe not possible” , which happened after a longer drive on a very rainy day. I let the car sit for the night and everything worked fine the next day and for two months on without problems. Three days ago I again had about an hour drive on a very rainy day and parked the car in a public parking garage. When I came back to the car the day after, everything remained black on the screens. No chance to get the car started again by myself. I called for help. The help service connected their 12V to the system and the MCU eventually powered up again showing following errors: DI_u14/GTW_w018/BMS_w123/BMS_f123. Since the next Tesla SeC was just 4km away from the garage, I got the car towed there today and I’ll let Tesla at least make a diagnosis. If Tesla just offers the option of HV battery replacement, I’ll probably schedule an appointment with EV clinic.
