My convertible roof has stopped working and I am 99% sure this is due to rear drivers side window not working, any recommendations for spare parts / quote to repair? I am ok with 2nd/refurbished parts. Audi dealership gave me part no

Do the windows drop slightly when you open the door (when it was working), then rise once shut?

Not familiar with convertibles, but assuming as frameless doors, then this would be the function. If that’s the case, then first suspect would be window regulator motor.

Accessing window regulator, then strip out interior door trim, which is likely Torx screws and clips.

If you had access to VCDS, then a scan would be worthwhile too.

Hi, yes the front windows do lower when opening the car but the rear ones only go down when activated by roof opening or window opening (3 door).

This video is as good as any (2010 A3 Cabriolet). Seems the window motor is behind plastic trim which uses a mastic to seal. That’s likely to be the hardest part. Other tools will be deep socket or Torx for any screws, 10mm hex socket, etc. Electrical connections can be a pain too. Invest in a head torch, and a couple of small screwdrivers for these connections. Regards the motor, normally daft money from Audi. Probably made by Valeo anyway, and suffer water ingress. Either the physical connection or the motor, so check these when stripping out. Take the part number and source from EBay. I assume the motors may be similar to the fronts? You can double check on LLL Parts.

I wouldn’t have thought it was fuses if other windows work, but hey, check anyway.
