My fix was to give the wiper arm a bit of a tweak, it always worked. As they say in the aircraft business, " a miss is as good as a mile".Yes it is the wiper arm, it taps on the screen and chips it. The screen is structural, a crack forms at the chip then runs across and up the screen. The crack becomes noticeable months after the chip but can happen faster in winter.
Lost two screens to MOT testers, one to a flyer poster and one to a speed bump. The fix is to keep the arm joints in good order and when the Audi rubber screen protector buffer drops off, it doesn’t last long, tie on a 9v battery terminal protector cap with strong fishing line.
I can get a picture if that helps. .
I will add that the first sign of the problem is as the arm and blade deflect over time the rivet starts to abrade on the glass and squeak when the wipers are in use. That's how I found the problem.
