I fully understand why you are concerned about the ramifications of the leaking sunroof but I am puzzled due to lack of information from Audi. I have a sunroof and I have never had any problems with it including leaking. I am sure that there are many Q3 owners who have had no leaks. So, what is the difference between the leaky sunroofs and the non leaky ones. Is it a tolerance issue, a build issue, a quality issue or what. The problem that I and many others have is, will the sunroof start leaking further down the line. I would appreciate if when you go to the dealer that you try and obtain details and publish them. And, you are right to be concerned about the electrics. They can be very expensive to replace.
