2009 Audi A4 Quattro Q&A
2009 Audi A4 Quattro Question: What makes the car stall, sputter, shake with epc light on? How much to fix?
Most of these issues can be caused by a vacuum leak in the engine or a problem with or the electronic throttle control. Specialized diagnostic equipment is required to test properly which the dealership has access to and also our shop has access to. Most independent shops do not have the level of training or tools to properly diagnose this system.
