I went home and parked the car, the next day I tried to start the car and it started but then it shut down and I got all kinds of light on the dash.
I did some searching and some people on some forums said it might be the alternator or the battery along with the ISM, I replaced all those (band new) and still shuts down. I ran DIS and I get a DME - 2B9C DME: Control Unit, internal fault: Overvoltage error.
Does anyone know what this means or what it can be? 
Thank you. |
You're gonna have to take it to a shop/dealer.. This is the F12/13/06 forum so most of us are still under warranty and this would just be a malfunction the dealership would handle.
