As I have already read in some treats, problems with audio workshops are self-explanatory. however, as I had to find out, it is not only due to the workshops but mainly to audio itself. my tt is about 4 months old and was already 8 times in the workshop. only it is a huge act to get rid of the defects every time, because audio doesn’t want to know about the defects. the last time I had a strong vibration in the engine room when the air conditioning had a lot to do. the we rkstatt worked out 3 appointments for 3 days (3days!!) on the car and was able to fix the error at 3 times after audio suddenly pulled out a fault report. At the moment I have a creaking while steering, since I have already read something, probably should be a knocked out steering bearing, but audio knows of nothing!!! then would be still a bubbernoise behind the glove compartment after I turn off the car, that could be a defective heat exchanger, but audi knows nothing!!! and next Monday did I have an appointment in the workshop to look for and how much days could not be told. had anyone of you ever the same defects??? can you tell me in which workshop they were repaired??? so I can only say the tt is only scrap: beautiful design and inferior technology and parts of bulky waste.
