Last night I pulled my headlight switch (87 Wolfsburg, but I believe this
would apply to all models) to verify type before ordering a spare.  While
counting   pins, I noticed the years of dust-covered gunk, so today I hit
it with spray contact cleaner.  Among the crud that came out were two
centipedes.  I checked both the Bentley and the archives and see no mention
of centipedes, so I assume they're not original and I'm better off without
them.

Old lesson repeated: cleaning stuff is a good idea.
Also, in case there's an entomologist reading, I ain't up on my phyla,
many-legged critters are pretty much all the same to me.
