I got an Audi A4 2007 2.0T, and I have to say that i've had quite a number of problems.
My car is in the shop right now getting my high pressure fuel pump, camshaft and follower changed under extended warranty.
Personally, I haven't had that good of an experience with Audi, and have experienced a number of issues. Owning one, if you really do want to get one, make sure you have warranty. For my repairs, the cost came to approx $3000!! Nice car, but not worth the price!
