Thanks for the replies, I probably didn't word my query correctly, I have checked and they are defiantly OEM. I'm just unsure if they were an optional extra or something as I haven't seen another A3 on Auto Trader with this style of wheel or any wheels of the style for sale on Ebay.
Trying to go down the route of repair again but 9 x out of 10 these repair places can only repair cosmetic damage rather than structural. Found a local bodyshop that may be able to help, fingers crossed.
