Hey everyone. Working on an 2001 Audi A6 2.7t and I believe my TCU is bad. I opened it up from the passenger side floorboard and noticed it was wet and got corroded. The shifter assembly will engage into all gears but the car will not move. It seems to be a "limp" mode. I've reset the ECU and manually reset the TCU. Anyone have a VAG com I could borrow? or possibly another TCU. Any suggestions on what to try? Thanks
