....and if you have these I think you can chance your arm with VW and they'll change them for you as these were recalled due to the corrosion. You may have to pay a bit towards them but you might be able to get a new set of wheels for about £60.
Been there, done that, got the t-shirt ;-) - we are on our
third set, 2 sets of replacements under warranty but that expired over a year ago and the latest set have now gone the same way.
However I'm relaxed about this, we did well to date and there's a great wheel refinisher I've found who can refurb them for me (and, crucially, lacquer them all the way through for permanent protection). He's already done my Elise rims for about £40 a wheel - ironically, when I delivered those to him, in the golf, he laughed and said "I'll be seeing your GTi back in here in a few months mate!"
The key thing apparently is the full lacquer...BBS, and many other rim suppliers, only lacquer the outside edge of OEM rims to save costs, and brake dust and corrosion creeps in from the inboard edges. Very poor IMHO.
But such a great looking wheel, we'll be sticking with 'em!
Ta for the pointer though.
