 The 2.0 liter turbo jerks a lot and gas mileage is average.  Rides great on the highway but too "loose" in the city.  I have had several problems with my car and am just glad it is under warranty (though a new battery is not covered). My battery completely died after two years.  The clip for the sunshade on the Open Sky system broke (as is common) and was replaced by a non-matching black clip (interior is grey).  At 21,500 miles, my manual transmission broke where 1st gear and reverse did not work.  My car is currently in the shop (over one week now) and Audi is going to replace the transmission since they are afraid the problem could spread to the other gears if they rebuild it.
