This metal tool is not suitable for new Audi sealing caps. If you tried to make it work, it would scrape the crap out of you. It might have worked on older discs with a lot of space between the plastic cover and the tab, but it might work on old wallpaper. I would just order some official thin plastic tools from Audi. They only cost a few dollars and should be used a few times before they wear out. =1&refRID=KCESDBNKDMC9Y0KFSKFN
