I have notived that the bottom two corners of my estate rear door are touching the bumper at the bottom when it's shut and it's wearing the paint off....I dont want to adjust the door can the bumper be moved down a bit and how easy is it

The sides of the bumper are held on by two bolts each side, these are accessable when you remove the "carpet" from inside the rear 1/4's, you may be able to loosen them off and pull the bumper down whilst tightening them back up again.

Have you had the towbar on yet?

If so I wonder if they have refitted the bumper correctly?

Cheers
