I don't want to scare you but the problem is "kuch cheezein" show case mein he achee lagtee hain, these German cars are only good until the Warranty is there after that you need to own a bank to keep these on the road..... This is not what I read but I have EXTENSIVE experience with Audi's,
Audi makes it a point so US model ke parts are not compatible with European or Canadian cars No mechanic wants to touch them....... Audi are known Money pits so stay clear
