you made a huge mistake buying the audi!!!
My roommate has a 01 1.8t quattro and it has been nothing but headaches!
besides the huge list of warranty repairs, Audi screwed her when one of the oil passages going to the head clogged up and caused a cam bearing to seize up. the car had 47k on it and audi said that since they couldn't find evidence of her first oil change at the dealer, they would only cover the parts. the oil change was done elsewhere, but it still cost her $1200 in labor. this is when the car still had a full warranty.
the most recent issue was when the car went in for its 50k service. she complained that the steering wheel was making a "crunching noise" when she drove it. they said that they couldn't replicate the condition(it neeed to warm up first), she just took it in for the 60k service, and low and behold, they found the problem(s). wearing ball joints and a leak in the high pressure hose in the power steering unit. "the car is out of warranty, take it up with the warranty people." no problem I figured, its documented. wrong, audi agreed to pay for only 25% of the repair. the cost is over a thousand.
ran ok when it was new though. even all the mechanics that I know that work specifically on german cars say you can throw thousands of dollars at them, but they never run like they did when they were new.
all I have to say is, keep your checkbook handy.
