I've saved a few posts from people in the past re:ABS.. you
can find them at

ftp://ftp.doe.carleton.ca/pub/chrisp/bmw/abs/

they include a wiring diagram, some part numbers and tips
on troubleshooting

when I get around to it maybe I'll squish them into some kind
of FAQ.. sigh

nope, I'm pretty sure all bmws had 4 sensor minimum 3 channel ABS
