09 335i automatically accelerating and decelerating
Hey everyone,
Car is currently at the dealer because I was doing maybe 70 holding constant and I started feeling a slight jerk back and forth. I switched to live MPG on dash and it was jumping from 32 to 26 and back and forth. I would accelerate and it would be fine until I would hold it at a constant speed. The dealer cannot seem to duplicate. Has Anyone ever experienced this? |

Well dealer figured it out. 3 injectors were clogged so it looks like the ECU was trying to compensate AFR to fuel PSI and it was fluctuating causing this. Hopefully get her back monday
