well after steve got home he rang his friend in Germany who works for Audi.
He has just rang us back and we so say know the poss prob.
theres 2 things after market car glass companys dont do.
1:He said first its Alloy body so twists unlike norm cars and that they need/ should be fitted different.
2 the tape windscreen companys put at the bottom isnt the same as Audi. (AutoGlass tape sponge is about 5mm wide and thick and soft i think)
Know our autoGlass has also rang our friend Audi and Audi have confirmed to them there needs the Audi sponge before fitting (perhaps Ian might confirm this sponge also.) as we didnt see it before they pulled it out the first time.

So now after there chat, its now on order from Audi that will take upto 10days to get it.

P.S 4th time around think we got a rat in the car as its to loud for mouse.
AutoGlass did tell us one way to cure the noise.............. wait for it ................ turn the stereo on louder.
