creaking door seals
As you know our e-34 cars have a soft rubber gasket trimmed with the interior color and materials on each door. The gasket is one piece and press fits around the inner doorframe.
I found today that when you press on the gasket it slightly moves and squeaks/creaks in some places. I sprayed a synthetic lubricant (I used Super Lube), on the doorframe area under the gasket and pressed the gasket back in place. Afterwards it did not squeak when I pressed on it.
Not sure if this is any help. However, it seemed to help my car with noisy door seals.
Good luck.
