Hi, I've just bought myself an Audi A4 and the wheels have a dust cap for which I am unsure how to remove, does anyone know what is the correct way to remove them? Thanks

 

You need to stick a hook of some sort into that little hole just below he Audi rings in your photo and pull out. They come off fairly easy.

There SHOULD be the tool in the spare tire tool kit in the trunk for removing the cap.
