Thanks for the help guys! Firstly this was indeed the toughened glass heated rear window. Also to be clear there is no way I would attempt to do anything with the fiendishly complex folding mechanism! I'm assuming the cloth cover attaches to the mechanism at multiple points. Waiting to get the car back to see what I can discover!

Sooo.... I loaned my A3 Cabriolet to my son as he needed a car for his family over Christmas. On arrival with in-laws he stowed the hood with 'something on the parcel shelf' and the back window exploded into a thousand pieces. It seems that the window is not a separately replaceable item and I'm looking at replacement hood... 😒 So I have choices ranging from £250 (replacement from scrapper fitted myself) to £2150 (new OEM-spec hood fitted for me). In between I could get a new aftermarket hood and self-fit for about £1118. So here's the question for you forum types. Can anyone point me at any information about doing this myself? I expected someone would have put up a YouTube showing how it was done but I haven't found anything. In my youth I pulled engines out of Minis and stripped them down so I should be able to do it but I've got rather lazy and timid these days. Any help gratefully received (and if I do it I may make a YouTube...).
