The answer is McLube SailKote!

With the caveat that it's only been two weeks since I applied the fix, so far it has completely eliminated the squeaky / creaky door seals that afflict the E39.
Before this I'd tried everything: silicone, Gummipfledge, silicon remover and then Carboflo (at 2 gold bricks per fluid oz), waxing the metal where the seals contact, using Klasse on the metal, etc.
These either didn't work or, in the case of CarboFlo, didn't work for long and yes I removed every last trace of silicone before applying.
SailKote is a waterproof, dry lubricant that you can find on pretty much every sailboat on the water including mine. It's great for any kind of plastic/metal or plastic/plastic contact, including cloth and other porous materials (like sails...or fuzzy E39 door seals). And it's cheap! I imagine that a $15 16oz can would last pretty much the life of the car. There's no buildup of crap, it doesn't attract dirt, lasts a long time and is, of course, waterproof. Get it at any West Marine or from their website.
Application is easy: just spray along the fuzzy part of the doorseals, let dry for a few minutes and you're done. Now I'm just waiting to see how long one application lasts but if how it works on the boat is any indicator, it should be awhile.
Here's the info from the website. Give it a try, I'm curious to know if it works for you as it has for me!
"Sailkote is the easy to apply high-tech, high performance dry lubricant that makes sails, hulls, rigging, deck hardware, and anything that moves on your boat run smoother, work more efficiently and last longer than you ever thought possible.
Team McLube Sailkote is the only dry lubricant currently available that has been specifically designed for marine use. Sailkote is a translucent liquid that sprays or wipes on and completely dries in seconds. So, unlike oils, silicones, and waxes, it will never attract dirt, water and contaminants that eventually degrade lubrication performance.
"World class" sailors across the globe from maxi-racers to sailboarders are enjoying the benefits of Sailkote's advanced dry lubrication technology. The same dry lubricant technology that has been developed for, and race proven by America's Cup Teams, Olympics Medalists, and One Design World Champions.
Discover the difference Sailkote can make in your sailing performance and enjoyment. Examine the cruising and racing applications pages for complete application information and important performance enhancement tips. Just as the sailors of nearly every America's Cup syndicate have discovered, no boat should be sailing without the benefit of Sailkote.
It dries quickly to a hard, smooth, ultra-slick, hydrophobic dry coating that bonds tenaciously to almost any surface. And because Sailkote is a dry lubricant, it will not attract dirt or contaminants and will not transfer to other surfaces, or you.
Sailkote is typically five times as effective, and lasts much longer than, wax, oil or Teflon® based lubricants."
