 Purchased Nov 8, 2011. Odometer now shows 4015 miles (as of Feb 10, 2012 when it was towed to dealer). Beginning at about 1000 miles, engine made serious noise when first started in the mornings. To an untrained ear, it sounds like a bad bearing noise emanating from something at the front of the engine. Car has been to dealer service twice for a cumulative 9 days. Techs and Service Advisor have listened to audio recordings of the noise, but report that they cannot duplicate the problem; hence, they cannot fix the problem. I found several YouTube postings by A4 owners with the same problem. Dealer says, "it's normal," yet, it did not make the noise for the first 1000 miles.
