in all seriousness, it MIGHT be your tires. i had a noise like that which i
could not pin down, and finally asked a friend who runs a tire store. he
asked me if i had radial tires. i said yup, and he told me to rotate them
front to back. it seems that vw vanagons and bmw's have a peculiar front
suspension that causes a strange wear pattern on the little "islands" of the
tire pattern ... the rear of each island wears slightly more than the front
edge. so they start making this "cupping" sort of sound as you drive along.
really wierd sound. anyway, i rotated the tires and about 300 miles later,
the noise was gone.

go figure.
