BMW i7 G70 HVS errors after update
Hello! I updated the unit software and coded the CCU2 and HVS on a BMW i7 g70 using ё_5у5 Ultra. I then added a certificate for the CCU. However, the car is displaying numerous errors regarding the high-voltage battery and isn't charging. A friendly remote connection 5ёяvїcё fїжed the problem but didn't explain the cause. What could have caused the errors? Should I have saved the battery cell values and added any other tokens?

Maybe the module was repaired with a virgin dump from another car....
If so, you will need to either replace it or repair it again, and its software must be older than I-Level xxx-11-25... |
