Hello, new owner of 905593 Avus/ebony/wood since Nov 2013. Car has 88k miles and to my knowledge is completely stock. Build date 10/03. Wasn't able to confirm last TB change at time of purchase. So that and other misc maintenance planned for spring. TC and trans seem to be in good order. Tip-mode in 5th gear doesn't slip. Also, my first Audi. I think I chose the right one
