Hi, does anyone know how to access the passenger ( US model) door mirror mounting, mine is slightly loose and vibrates while driving. I'ts not the mirror itself, but where it mounts to the door. I copied a photo already on this site to illustrate the area.

If the entire mirror is loose, you need to tighten the mount. Carefully remove the black trim piece in the inside of the door, and under it is a Torx bolt that will need tightening. A drop of Loctite on the threads wouldn't hurt while you're at it...
