Any trusted Tesla 12V battery supplier in ICAD that actually knows the calibration?
My Model 3 has been sitting for a while and now it's completely unresponsive – won't unlock, no screen, nothing. I know the main high-voltage pack is fine, but the 12V auxiliary battery is clearly dead and has left the car bricked. I've read that this is common in the heat here, and that unlike a regular car, you can't just drop in a new battery; the vehicle may require a software configuration update so the BMS recognizes the new battery type, especially if you change from the original spec . I'm in the ICAD area of Abu Dhabi and I'd rather not wait weeks for the official Tesla Centre appointment . I've seen a few places like Exotic Auto Services and EV Experts in Mussafah that claim to handle Tesla 12V battery work and use safe procedures , and there's also a mobile service that covers Abu Dhabi with AGM options . But what I'm really after is a Certified Tesla car battery supplier in ICAD that knows about the 12V Battery Type configuration and has the tools to do the system reset properly, not just a garage that treats it like a standard swap. Has anyone here used a local shop in ICAD or Mussafah for their Tesla's auxiliary battery that actually handled the configuration correctly?
