After swapping standard seats to sport seats, I´ve been belles by airbag error dash icon, and passanger restraint system error.
Fault code is 9915 Communication error SBE1. I tried to code out occupacy sensor but with no success. Probably because I can not communicate with that module.
I checked the sensor to confirm that wires are okay and noticed that - my old seats had 2 wires and a sensor box. New seats have 3 wires which go straight to yellow airbag harness under seat.
Can I use the sensor from my old seats and install it no new seats? How should I connect the wires if I only need two wires, but have three?
Thank you

BMW ABS systems are real finicky. I would try and find a wiring diagram to get it wired up. Then you will need to set the timing so it can communicate with the new airbag system installed.

Where could I find diagram of underseat yellow harness wiring so I would find out which wire is what?

I installed older 2 wire passenger occupancy sensor to newer 3 wire occupancy seat - error deleted and doesnt come up when passanger sits so seems to be fixed..
