W169 Rear Bumper clips

[Jadee]

Can anyone tell me how the rear bumper is secured on a pre facelift 2008 A Class W169.

All is OK with ours apart from one side where it clips onto the rear wing - it seems as though the bumper needs lifting slightly to keep the clips secured. Its secured OK by the wheelarch but the clips come undone near the tailgate.

The other side seems fine, any clues anyone.

Does anyone have any instructions for removal and refitting the rear bumper on a W169 A Class - it seems they are mentioned on the forums but I cannot find any links.
