Automatic Transmission problems of the 2004 Audi TT

2004 Audi Tt 3. 2 liter, dsg transmission, 32,000 miles. At random times, the engine would suddenly disconnect from the drivetrain for a few seconds, a serious safety issue when merging onto a freeway, or crossing a busy street. This occurred many times over a period of weeks, until I stopped driving the car because of safety concerns. An error code showed a speed sensor failure, but replacing the sensor did not fix the problem. Ultimately I had to have the mechatronic unit in the transmission replaced to fix the problem, at a cost of about 3,200 dollars. I have the defective mechatronic unit in my possession.

Recently purchased an Audi Tt 3. 2 v6 2004 dsg model. 51k on the clock. Whilst driving along the motorway suddenly the car seems like its been thrown into neutral and a sudden loss of power. No warning, no engine management light, nothing. This keeps happending sporadically approx twice a day and according to Audi it seems as though im going to have to cough up for a new gearbox which I deem to be totally unacceptable. Surely this must require Audi to review the dsg gearbox. ???.

2004 Audi Tt roadster dsg/mechatronic unit failure. Engine shifted into 1st gear on 294 northbound while driving 55 mph in the center lane! lost all power and prayed that I could get to the shoulder without being hit. Road the should in 1st gear with hazards on until I could exit and limp my way to the dealer. Estimated repair $25000. 00 I have been unemployed since sept 2009. Maybe I should have been hit and killed! just put $710. 00 in rear brakes and new wipers on. This repair is insane. The unit should be recalled. I could have lost my life as well as my passenger which was my mother! no warning of any kind to alert you that something is going to happen. Very very scary!!!.
