I have a 2001 A-6 with a 2.7T motor. took the car to an authorized Audi Dealership for service, suggested (at 84K miles I replace the tranny fluid and filter. So I said yes. got the car back and less than 20 miles later got a check engine light. took it back to the shop and the code was P0741. they said this means the torque converter needs replaced. wait a silly minute, you just serviced this??? Well things like this happen! OK so I take the car to another authorized VW/Audi shop, they check the tranny and it is overfilled. They drain it and the light is gone. it stays off for about 1,000 miles then again it shows up. now it's on sometimes and off sometimes. Take it back to the second shop and they say might be a bad sensor. Car drives and shifts fine. It's been that way now for 7years and 58K miles.
