Hi Guys, Read on a post some time ago about my problem but cannot find at the mo. I have just changed the 18" SLine wheels fitted to our SLine Sportback and fitted a set of A4 SLine wheels. Problem I now have is that I can hear what appears to be a scraping somewhere on the rear when I give it some beans on our uneven roads. Think I read somewhere that the plastic wheel arch surround catches when under load and a screw into the arch will sort. Could someone please let me know what to do otherwise original wheels will have to go back on. Thanks in advance.
