Rear Bumper Loose

Hi, new on this forum - so if I get things wrong please advise! Just bought a 2012 SD4 pure tech with added extras. Bought from partners parents who have not been the most careful! Rear number is showing a fair bit of space between bodywork and top of bumper at both sides at rear wings - looks like it has come off or broken trim clips. It's not going back into position as tends to be getting pulled down when needs to be pulled back up onto a clip or something - can anyone please tell me if & what clip has broken & if bumper will need to be removed to adjust back into place?
Selling my 11 year old BMW which is in immaculate condition so used to looking after my vehicles.
Thanks very much.

Not had the bumper off, but does this pic help?

   

Hi Philskill,
Thanks it does! I can see what's where & see the area under the rear bumper at the wing that I would never have been able to see! Think I can figure out from here what clips are required to set back into place I'll take a look at the oem site for diagrams - used this for my bmw & it's a great help! Had IN PA diagnostic lead & software for BMW - will need to see if there is something similar for RR as it saved me a fortune in misdiagnosis! Thanks again H

You will find that handheld diagnostic uints are available from some of our forum sponsors.

Perfect thanks - I'll take a look
