Heated rear screen & door mirrors not working

[tonupkid]

Hi Bex
My D3 HRW was not working either, apart from just 2cm across the top.
I could see that the black edging down the OS side of the screen had delaminated.
Audi confirmed that this was the problem, so I asked them nicely to put it past their warranty people, and to my surprise they replaced the screen with a £325 contribution from me.
My car has done 95k and is 6 this year, can't complain.
Incidentally, I think the elements are inside the screen and can't be damaged by scratching.
Perhaps this is a known fault, have a word with your dealer.
Good luck

Oh yes, my mirrors weren't working either, not sure they do now
