    My torque converter started going around 80k, but around 100k it began to really act up and had to be replaced. Complete garbage service from Audi and this is by far not a rare problem, LOTS of user's have this problem and a class-action suit should be filed. The failure rate is ridiculous and there are many mechanics reporting faulty designs in the torque converter itself. The "joke" at an Audi dealership here in NJ that is owned by my friend's father and a partner, (Mr. Reynolds); Every Tiptronic Audi from 2000-2005 will need a torque converter and every car with the 2.7t (twin-turbo motor) will need turbos because of faulty designs. What a sick joke especially when his son said that to me after the fact I bought the car and had the work done, if I knew that then I would of never bought one. Like I said, I talk to the owner's son and other mechanics at Bernardsville Audi in New Jersey this is a serious problem. Mr. Reynolds is in partnership with another person and they also own and operate the Mendham Audi dealership.

    Check engine light comes on, goes off, no pattern. Dealer and independent shop both state faulty converter, yet symptoms dealer said I would experience are non-existent. No slippage, no change in gas mileage or performance, nothing. I do not believe this is anything more then a sensor or computer problem.

    CEL after driving in snow - code states TCC most sites point to faulty converter... cleared code and it is back on within 20 miles. Just bought it and it's a fortune to maintain so far.... but that's the price for a good German engineered car, right?

    Haven't had it fixed yet so don't know cause of issue but the check engine light has come on and off since about 20,000 miles. Dealer just tells me to ignore it. Haven't experienced any engine problems as of yet.
