Diese werden ja ueber die Jahre rissig und zerbroeseln, Wasser kann dann in die Tuer.
Hier mal Bilder wie es am Z3 geht, mit englischer Beschreibung.Fahrzeug: 1997 Z3 2.8.
Here is the port to access the push plate, on the passenger side door:

Remove with a knife. You can see that I really mangled the plastic trying to use a little flathead screwdriver before I got out the knife. It looks like you can get under the tabs and pop this piece off easily, but mine required a lot more force than I expected. Don't scratch up your trim! On the driver's side, I used just the knife and it came out cleanly.

Open! The plate that releases the door handle surround is on the right (outer) side in this hole. Reverse that for the driver's side. A flashlight really helps here.

I used an allen wrench for the "push" part of the job:

Now you can remove the trim piece, and clean out the gunk while you're in there.

Here's a fancy tool I made for pulling the plate back after adding the new gasket! The latch has a lip that is open on its left and bottom sides (right and bottom on the driver's side door). Again, use a flashlight.

All done. Before & after shots:

This is probably the perfect tool for removing the handle cover - a paint can opener. It can do both the "push" and "pull" parts of the job.
