I'm about to buy an LCI E92 330D M Sport Coupe (13 plate) car but the previous owner seems to have been a little careless reversing and has put a small dent in the rear bumper area of the car, the car has the retractable tow bar option so that might explain what happened! The small dent seems to be just on the 'diffuser'? part of the rear bumper and once this part is switched should all look OK again I think.
Having a search on google it's possible the part number may be 51128041191 although I've also attached an image so you can check I didn't get mixed up and trying to quote the wrong part!
I believe this part comes ready to fit with a few clips/screws but if that's not the case and it needs to be sprayed etc before fitting please let me know. Car is Space grey Metallic if that affects the order in any way (think these parts all come in the same colour anyway?)
If you need the last 7 digits of VIN/number plate to confirm exact part and get price just send me a message and I'll send it over.
