I know there has been plenty of posts about this in the past and is a common problem amongst A3's (why?).
I have had two A3s now and the first one didn't have this problem at all ever, my current one hasn't had this problem wither... until now!
Did anyone actually get to the bottom with it with a 'proper' tried and tested fix (by audi or otherwise) i know there were lots of DIY potential remedys banded about but did it ever get properly solved to the point where dealers know exactly what to do to fix this problem? Last time i read a post - bending the door was mentioned!!!!
