When I took my car in for its first oil change service I got them to look at my flappy black gloss, rear spoiler. They fixed it no problem. Didn't ask what with as it seems well stuck down.
@remlapeel I can't understand why you need an entirely new spoiler unless it snapped or fell off? Shocking they can't get the part sooner - not good of VW that!
I've made my views clear about the design and engineering of the thin, black, gloss spoilers on the rear window. They shouldn't be glued. They should employ a metal clip which hooks around the side of the glass window somehow. That would have been much more secure and pretty cheap too.
