Hello! First let me say I've been lurking a few months while shopping for a Tesla. I took a gamble on a 2013 Model S P85 with high miles (155k) that in the listing stated an inability to charge.
I've looked around at other posts and seen similar issues and am curious if I should look into dropping the HV battery and checking for loose voltage sense wires like this post.
When I towed the car to Tesla they said I need a new HV pack, and I don't doubt that that is a possibility. However, when I went to get the car, it was clear they didn't move it but just supplied 12V to the car and got a remote diag (which they mentioned in the service summary).
Service Mode Codes:
BMS_u008_limpMode
Acceleration and top speed reduced
BMS_w107_SW_Cell_Voltage_Sensor
Vehicle may not restart
BMS_w018_SW_Brick_UV
Electrical system power reduced
BMS_f107_SW_Cell_Voltage_Sensor
Service is required
Here's the kicker. The car couldn't drive when I purchased it. It's showing 0% and 0 miles. The charge port is keeping the lock up but I can lower the lock with part of an old AAA card and plug the charger in. It will try to charge for about 30-45 seconds, then stop. I can then use the button on the charger and control the lock. But I cannot control the charge port lock before manually lowering it with the card. I wonder if the car is blocking me because of the BMS codes?
I feel like I wrote a book but hope someone might be able to point the way (and maybe help me save $16k in the process). Lastly, if I did need to replace the pack, has anyone successfully been able to keep their old HV battery for DIY projects, or does Tesla SC take them as a core?
Thx!
Joel
