I am trying to remove the front bumper on my 05 SLK 350 in order to replace a few parking sensors and sort some rust around the headlights.

I have followed the WIS data sheet, but I am stuck on the bolts behind the wheel arch liner that connects the bumper to the wing.

What size are they (10mm?).

I can’t get them to turn (they sound like they are turning but they don’t seem to unscrew) - any tricks to freeing them up??
