2001 Audi A6 Quattro Avant 2.8L Misfire, MIL Lamp on
Posted to European Driveability on 8/28/2008 9 Replies

The car has a lean miss at idle and a slight hesitation on accel. The mil code P0174 (I believe Audi code 16558) came back in a couple days. I don't have a VAG scanner so I can't go too deep into the car. Can a O2 sensor cause this on #2 bank? Should I measure...
