It should be possible to repair that. The only concern I'd have is finding the correct color match.
Could be worth ringing VW and see if they know ?
Another thing I'd think about doing (which I done with my Lexus) is to contact VW and ask them for the contact details of the people who do the wheel refurbishments as you need to ask them a couple of questions about the work they have (ahem) ALREADY done.
Hopefully the dizzy blonde reception will give you their number (like the Lexus one did for me) and you can go straight to the professional refurbisher and cut out the VW middle-man extra charges
