OK, I've done this now - Step through....
- Remove the 1 bolt on the wiper spindle, then remove rear wiper (WD40 helps loosen it on the spindle).
- Open the bootlid. Remove 2 screws, then pull the Trim to remove. Its also held in with 6 clips, so a firm tug helps alot!
With the Trim now removed, the rear wiper assembly is now accessible...
- Remove the electrical block connector + water pipe, from rear wiper motor assembly.
- Use plumber putty to cap the end of the pipe to seal, to prevent it leaking.
- Unscrew the 3 bolts that secure the rear washer motor/assembly.
Re-fitting - Refit boot trim, helps to align it around bootlid latch first, then clips, then 2 screws.
- With bootlid closed, pop out the Rubber ring thats left in the glass.
- Use a 24mm Aerial grommit (available in Halfords), to neatly close the hole.
Job complete.
Are you going to disable it through VAG.COM too or just leave it as is? I just dont see what harm could come of accidentally, once in a blue moon, turning the rear wiper on...? Surely it just wouldnt do anything?
