I just purchased JB4 and installed EWG connectors. Running Map 2 on 2019 M5 Comp. After driving, I obtained drivetrain malfunction alert. JB4 shows the following codes:

Diagnostic mode means you press the start/stop button 3 times with the foot off the brake. That is the only mode the car will allow you to delete codes with.
Mileage isn't going to be effected even if installed wrong so likely you're just racing around more testing stuff. |
