 I just bought an Audi A6 2.7T 2003, and I think I made a mistake. After only having the vehicle for 2wks I need a torque converter, mass air flow, battery, and the tiptronic is failing; $3,275.00 to fix! and they say there may be more to do once the mechanics are in there. Kinda pricey to maintain but going to make it mine and fix it up like it's a classic!
