Can M440i Rear Diffuser be Removed Without Removing Bumper?
Has anyone successfully removed/replaced the rear diffuser on a M440i WITHOUT removing the entire rear bumper?
Maybe just by removing the rear under panels to access the bottom diffuser clips? Service manual shows entire bumper removal, but looking at the clips I can't belive that is necessary. Looks as if you unclip entire bottom and sides of diffuser it would swivel up and then pull out of top mounting slots I have a new CF Diffuser to install and not looking forward to all the fiddly bits required (trunk trim, tailights, etc) to remove entire bumper

After checking with RW they recommended removing the bumper for install - took the car to my local shop & had them install both the rear CF Diffuser, CF Front Air Curtains & Front CF Spoiler since it required removing both front & rear bumpers & they are way more experienced than I am
They stated install was EZ, the new parts fit perfectly & they had no issues. Took them around 3hrs total for all & cost to me was $220
