      is it a solenoid? it sounds like it. if you can find even basic wiring (look on your harness to start, brown should be ground and green or red might be power). Then you can ground one post and apply 12v to the other and see if it opens (or closes).

          See page 113 in http://wedophones.com/Manuals/BMW/19...g%20Manual.pdf

          Looks like green/yellow has +12V and white/brown gets a ground signal (or something less than +12V) from the control module when the engine needs spark advance.
