My Audi A6 (SE) has an annoying problem - the front windows rattle slightly. There is a "pattering" sound from the top of the window frame on all but the very smoothest of surfaces. It stops immediately I open the (electric) windows, or if I press hard at the top of the window where it joins the frame.
Anyone else noticed this? Any way of stopping it? I've had it to the dealer twice, but they can't stop it.
Thanks
