905707, build date 9/03 (according to the door sticker) but listed as 12/12/03 on a warranty report I had printed from Audi (which also says the model year is "2004"). Not delivered until 7/2/04. Transmission replaced under warranty by Audi at 64,812 in 2013 (no idea what the codes were if any). Subsequent owner must've worked it too hard again because the car was towed to Level 10 in 12/2015 at 98,529 mi and had the transmission rebuilt there. Currently at 115k mi and drives like a champ!
