Let somebody back into your car with a trailer hitch receiver. That's what I did. It removed the plate bracket and did some damage to my bumper too and now, I had the holes filled and now I'm hoping the hide away plate holder will work for me so I can be legal. I'll be damned if I'm going to drill holes back into my bumper. It sucks that the 17 Facelift GLI will not accommodate a tow hook holder without obstructing the grill mounted parking sensor..
On a serious note, when I get home in a couple hours I will see if they are the type of clips that can be removed and re-used and get back to you.
