Hello, I'm new to this group (it's my wife's car not mine), and have been looking at the spacesaver wheel issue. As one would expect there don't seem to be many TTs hitting the breakers yards by us. Apart from the M5 Golf Gti mentioned above, is there any other car whose space saver wheel might fit? My local breaker said they occasionally now get A4s coming in for breaking, but I don't know if early noughties A4s even used space saver wheels back in the day, still less whether Audi uses common wheel stud placings. I've never owned an Audi before. Just as a general point, the money-making use of these 'gloop' injecting replacements for a spare wheel is an abomination.
