Thanks guys, I just contacted the last owner who informed me that he had the wheels refurb'd by his own business with a one off latex paint
The good news is that he has some left over, which he is going to send me so should be able to fix the scuffs.
I did contact my local TPS and was informed that VW don't have paint codes for wheels, so if they get mashed again it will be a four wheel refurb in a colour as close as the one I have now.
Keep the info coming.
