I bought this car 5 years ago in 2008 with only 28K miles and even though its fun to drive the repairs has been ridiculous. The factory warranty expires at 48K/4years. The car was 4yrs and 5 months when I bought it. At 32k the instrument cluster needed replacement at a cost of 1,250. At 40K the water pump needed to be replaced 1,850. At 45k the transmission needed to be replaced 5,200. At 56k the alternator, belt and tensor were replaced 1,650. At 72k the alternator was replaced again for 595. Audi should've replaced the the instrument cluster and the transmission because both failed before 50k but they washed their hands. After this experience I'll stay with BMW,never buy an Audi again.
This is my third TT of the MK1 series and is the best of the three in my opinion. The VR6 is a better engine than the 1.8 turbo. I have no timing belt woes to worry about, for example, because the cams are chain-driven.
What more I can say?! Fun to drive. V6 and DSG push the car to another level. Especially DSG, you have to try it to believe it. So quick and smooth. And the tuned sound from the exhuasts, it makes you feel like you are inside a F1. 4WD takes me anywhere I want to go even a trip to the nearest skiing resort in the winter. So versatile, I can put 2 golf bags at the back (both rear seats have to be folded down) without any problem. Put a car seat at the back(Yes, you can put a car seat at the back. My 2 year old daughter loves to ride in my red TT), it becomes my family sport wagon.
Be aware of the dual clutch automatic needs regular (frequent) servicing at a dealer, the hydraulic shifting controller must be in top shape to prevent a jerky ride in traffic. On the interstate you won't notice.
I must have just gotten the odd lemon based on the other reviews. After 75,000 miles in 3 years, I have spent over $10,000 in repairs and maintenance. This includes $5400 for a timing belt at just over 50,000 miles. The car is got a lot of pick up after the brief hesitation waiting for the turbo to kick in. It corners well and the stereo system is great, but that's about it. I have no desire to own another Audi. I have spent more repairs on this car than on my last 3 Toyotas combined and this car was far less reliable than my last two Volvos.
