Hi I have an audi a3 and im getting a little bit sick of my drivers side electric window as it seems to go down fine but when it goes up although it looks fine when I hit about 80mph I get a loud whistle coming from the top of the window, it is as if its not shut properly. The only way I have found that I can solve this temporarily is to force the window up myself whilst holding the button up too. This moves the window up slightly and the noise stops but as soon as i put the window up and down again the noise returns.
When I bought the car I noticed some scratch marks on both windows, they are about an inch wide and sit towards the back of both front windows near to where the locks are situated. They stretch vertically for the entire length of the window. Since I have had the car they have progressively got worse, it is asif they are getting scratched by something when they are operated.
Any Help on this would be much appreciated.
