I have a 2013 AH3 and a week after taking the car in for an oil change and inspection sticker, I'm getting a check engine light and a drivetrain malfunction error on iDrive (auto start/stop). I recall replacing a couple of batteries a couple years ago but I went to a different dealership that is now telling me I need a new auxiliary battery and O2 sensor. Are there three batteries plus the hybrid battery in the AH3? Or just two batteries plus the hybrid battery? I'm going to call the dealership tomorrow to find out exactly which batteries were already replaced. The first dealership I went to told me that they recommended replacing the battery cable end and they think that this could be causing the problems. Any insight would be greatly appreciated.

Hey man.

Ik6speed is banned.

As a result all AH3 owners now moved to Facebook BMW Activehybrid group.
