I purchased this vechiled 10 months ago. At 800 miles, the engine light came on. The crankshaft, throttle body and cam adjuster were all reported to Audi USA and repaired or replaced. I was informed by the dealer they wanted to replace the engine. Audi USA is saying it was only a bracket. The car still pauses and jerks when accelerating, and has an annoyingly loud vibration. I am not confident in the Audi brand anymore, and after 10 previously owned Audi - I am moving on to their german competitor.
