Topaz bathroom wallpaper peeling

I have recently bought a 2008 Topaz, i did notice some lifting of the wallpaper in the 'bathroom' before purchasing and asked for it to be remedied, which was done by sticking it down (badly) but I've since noticed that the wallpaper on the back of the doors is lifting and looking awful nearly all down each door.....there seems to be no damp anywhere, and if anything the area nearest the bottom is more firmly stuck......is this a  common problem and what do people do about it?  I've stripped one door completely and its fine underneath, but im not sure whether it would be easy to replace? Bit annoying really, as its spoiling the look of an otherwise very nice van!

I assume the doors you mention are the sliding doors, I had mine replaced under warranty due to A/S using too long screws when they assembled the van, so they may be available still from the spares dept. I bought my Topaz new in 2007 and didn't have any peeling problems with those doors, however the plastic cover on the wardrobe and toilet cassette doors did come away and was advised to stick them back with super glue. Watch out for cracks to the plastic in almost all of the bathroom area, I had mine replaced at 3 years, at some cost to me and when it cracked again at 6 yrs I did a P/X. Otherwise a great van.

 Just thought, not easy to replace the sliding doors as the dealer took a few hours having to remove a few cupboards etc.
