My friend’s 2006 Audi A4 2.0 started dying on her a few months back. She replaced the battery to no avail. She then took it to a shop and they seemingly fixed it. It died again. She took it to the Audi dealership. They charged her $1200 to fix something to do with the temperature/vacuum system. A few days after it was out of the dealership and supposedly fixed, it started dying again.
She has taken it back to Audi a few more times. They have replaced the knock sensor, the cam shaft, the fuel pump, and the fuel filter, all for another $1300 (they are supposedly not charging her labor).
We are stumped. Audi is stumped. The national Audi guys are stumped (yes, they called them in). My friend doesn’t know what to do. She is essentially paying the Audi dealership for them to experiment on her car. Anyone have any suggestions?
