Thanks Simon, I was just about to contact you when it came apart. The vents did indeed fall out but luckily enough they're in one piece so that good.
I vinyl wrapped one a few years back, looked ok but you just can't get into all those little corners properly, hope you have better luck than me.
I've an old one that I painted to put on the car but never got round to it and now I have a Mk6 climate control I never will. Oh and my "attempt" at painting was shockingly bad (and the reason why the next ones going to a professional) so I'll bin that one (below) or keep it to experiment on. Looks ok in the pic but that's because its out of focus!
