I can vouch for the Gummifledge. My new Polo had driver's door squeak issues and I could not find any cause for them. I even tried the rubber hose trick and it did not help at all. I then tried Gummifledge in December last year and it got rid of the noise instantly. 6 months later the interior is completely quiet. I intend to just use this treatment each year or if door rubber related noise recurs. I think I remember reading that this Gummifledge stuff is used in the course of normal BMW servicing by dealers.
It seems to be a good treatment just to preserve the rubber as well, so I used it on all the rubbers (4 doors plus tailgate). Also, when I was researching door noise in the forum archives here last year, mention was made to avoid using polishes or waxes on the painted areas inside the door frames. So I just use the Meguires waterless liguid stuff and a Meguires microfiber cloth for these areas.
