ahhh... speed sensor... that could be an issue... there is another thread going on right now about the speed sensor as well... you need to test if the speed sensor is reporting to the ABS module... there are pinouts of the ABS plug out there, i even posted it once... need to search the posts to find it...

diddy, do you have a multimeter that can measure a diode? that is what a bmw speed sensor is, a Hall effect sensor based on magnetic field and a diode...
