this isn't going to be much help as I need a new screen for my 1982 Audi 80 CD as well, but I also needed a screen this time last year and got one replace via the insurance for the £50 excess. At first, they bought a Series 3 screen but came back next day with the correct early screen. Only problem with mine was that on the first trip out after having the new screen fitted, the screen got a huge chip in it from a stone, ironically, it was from the car in front which I was driving and my wife was driving the 80.
