My brother has an 2005 A3 8P which has developed a problem with the wipers making a light knocking noise. Everytime the wiper blades return to the rest positon there seems to be a knocking noise and appears to be coming from the driver's side.
Have changed his wipers with mine and the same problem is there. Again have looked with the bonnet up and the blades and arm seem to sit well enough away from the scuttle panel. Annoying that we can't activate the wipers when the bonnet is up to really get a good look.
Any ideas would be much appreciated, thanks.
