John, Here's a copy of the post I made some months ago ~ hope it helps!

I have been a ?lurker? on here for some time, but now is a good time to post..!
I have 2.0TDI S-line (Sept ?09 build) with the ?wiper / bonnet? problem. Just have others have indicated the driver?s side wiper was hitting the bonnet in two places, one mid-way on the sweep and the other at the sweep end-point. Now I have a complete and utter distrust for anything to do with garages, so I decided to fix investigate it myself (engineers do that sort of stuff).
The problem is due to the wiper-arm securing nut being cross-threaded during assembly! The nut has an integral washer that should hold the wiper arm perpendicular to the spindle, when the nut is cross-threaded the nut sits slightly misalign to the spindle, the wiper arm then is off-perpendicular to the spindle and wiper hits the bonnet.
I removed the cross-treaded nut, replaced it with a new one, fitted it properly and guess what no wiper/bonnet contact (and back to approximately 3mm clearance).
So, in conclusion it seems Audi engineering and their tolerances are fine but the man on the production line has problems aligning his nuts .
Hope this helps,
I remember this having been brought up before but now I am struggling to find more info on it.
On inspection of the bonnet I realised that where the drivers side wiper arm exits and enters from the recess above the bonnet there are gouges out of the paint and metal due to rubbing.
Best way to find them is to open the bonnet and run your hand along the back edge.
Anybody else got this problem? What have the dealers done to fix it?
