By now, you've seen Bill's consistent posts that the diagnostic machines can't tell you what you need to know because they're all hooked up wrong (I'm surprised we know that but the BMW technician does not know that - or - maybe the BMW tech knows something we don't know ...).

But anyway, I "suspect" you're wasting your time testing the brake pressure sensor (even though Carsoft told me it was that was what was stored in my car also, I learned to ignore it). To my knowledge, I don't think ANYONE here yet has actually needed to replace the pressure sensor. (If they have, they should come forward now - and provide proof with a before/after picture.)

Please post a picture of your flying-leads setup as you will be the FIRST person here to have done this so you should give back to the team and enlighten us.
