If you have noticed some annoying squeaks in the doors, it's probably time to lube the weather stripping rubber gaskets. The dealer has this great stuff called "Gummi-Pflege", part no. 82 14 9 407 015 for $6.75 with the BMW CCA discount. It comes in a generous size tube which will probably last 10 years, Ref. Photo-1. It has a sponge applicator tip & just clean the rubber & wipe it around the entire perimeter of the door & doorjamb rubber.
