I have a 2006 Audi A3 3. 2 quattro with the dsg transmission. I was driving home from my 45k mile service(the last one before it goes out of warranty). I was doing about 45-50 mph going through the sunpass express lane. I lifted off of the throttle for a second and then, when I went back to the gas, no drive, no gears. The rpms shot up to around 7500 rpm's and the gear indicator screen lights (p,r,n,d,s) were flashing and I had to pull off of to the shoulder. And trying to pull over with no drive on the palmetto expressway in miami almost got me into 2 different accidents. I tried to select reverse then drive and sport mode on the shifter, nothing, screen still flashing and the car would not move. I called my dealer and he told me to call Audi road service and have it flat bedded back to them. About 15 minutes after the occurrence, I turned the car off and back on and it now was able to select a gear and the flashing stopped. I drove it very delicately back to the dealer and was awaiting a diagnosis. They said they are replacing the faulty transmission control/mechatronics unit. This happened on 7/24 and I am still waiting on the new part to come in. I want to report this because, it has come to my attention that I am not the only person to experience this failure on an Audi or Volkswagen car using the dsg or s-tronic gearbox. I want this to be documented in case something happens. I'm also worried that my car is just about to come out of the warranty period and, if I have this failure again, it could cost me thousands of my own dollars to have it fixed.
