Hello a recall notice came in for my 03' Audi A4 for etc sensor. (70k miles) took the car into dealer got it fixed. A week later or so check engine light came on and car was dead in its tracks. According to the dealer and two mechanics shops, its the transmission. Dealer price on transmission was 7,558. 00 total. Owe my goodness. . . . . . Car is worth about that. Since then I have been trying to locate a used or a rebuild transmission but their is not much of a difference in price because the transmission is so hard to fix and parts are very expensive that no one wants to deal with the car at all. Not to mention the difficulty that requires to replace this type of transmission for my vehicle model. Special tools and programming. Called nearby states with no luck finding a rebuild transmission. Also Audi does not make them anymore, making them even harder to find. I have been searching on the internet for the past 3 weeks trying to find some information on this type of vehicle and the transmission problem and I came across the same story from many Audi A4 owners. This is not a driver problem but a design flaw. Transmission is not fixed because I can't afford 7. 5k for a new one that will give out in about 50k again. This is not right and something should be done about this. When the car started to shake tremendously in the middle of turning onto a ramp to enter the highway I could of cause an accident easily. Through out blogs and website advice, their are countless number of people with the same problem. The transmission seems to give out right about 50-85k miles. I hope you can help.
