I have 3 small areas of whiteworm around the centre cap on the front drivers side wheel (mk6 GTD with 18" Charlestons). I'm OCD about they way my car looks, and the wheels are cleaned and sealed / protected regularly. Noticed the whiteworm for the first time a couple of weeks ago.
I've yet to take it in to the dealer to get them to (hopefully agree) to replace FOC under warranty - car is 31 months old so still under warranty and I've owned it from new.
If they suggest the wheel has been damaged when it's been removed from the car, it's never been removed since the car was built, unless the dealer removed it during the 2nd service!
Whether or not I get a replacement under warranty, I've been seriously thinking of getting a set of BBS and some decent tyres (still on original sh!te Bridgestones). If I do this, then I'll store the Charleston's until the time comes to sell the car, when I'll put them back on, and transfer the BBS wheels to the new car - if they fit. If they don't, then there's always a ready market for genuine, well looked after BBS wheels, so I wouldn't anticipate having any problems selling them.
