First time poster...... I have a damaged alloy on my A3 S Line and Audi are wanting over £500 to replace and fit a new one which is more than I was anticipating. I am obviously going to look elsewhere but I'm finding it all a bit daunting. Audi have given me the part number - 8P0601025BA. Its a 7 Twin spoke 18" I have searched online and on eBay and there are similar looking alloys but with different letters in the part number. Will these fit or do I specifically need the part number as given by Audi? Also, does anyone know any reputable suppliers to try? Thanks in advance for any help!
