Rear door not sealing properly

[Crofty1984]

Hi all, the top of my passenger side rear door isn't sealing properly. At the front top corner it looks like it's bent away from the sealing strip (but doesn't LOOK bent itself). Is there any adjustment that would fix it? The wind noise is annoying. It's also pretty hard to slide open/closed but don't know if that's related.

I'd look at the guide rails, they are likely to be the issue. You have 3 from memory (the B9 does anyway and it's been a while since I had an M59) so check they are straight and not "stickling out" or bent in any way, I would be sure that's the issue.

Chances are, one is out of alignment. Start at the bottom one, a steel rule 1m long, used on it's edge should confirm if anything is out by lining it up across all three rails.

Screwfix sell the 1m ones for a few quid (£8.99) . It should span at least two rails vertically and may show if one is twisted as per the other one. Check bottom to middle then middle to top across the front faces.
