B-pillar Satellite location?

Recently I took my '04 Z4 to a certified BMW shop and they told me that my B-pillar Satellite sensor for the airbag system has gone bad. The guy I spoke to hinted at a location in the door. I ordered a new part, but the Internet can't seem to tell me where I need to remove the old and insert the new part. Does anyone have a picture or description of where they replaced their SBSR module?

A B pillar in a convertible? With a satellite sensor?? I've never heard of such a thing. Sounds to me you probably went to the P.T. Barnum Repair Shop.

Sorry.
I stand corrected. Just sounds really weird.

**Update** Found the SBSR..

After some pretty extensive searching and randomly removing anything behind my seat that came off, I found the positioning of the B-pillar airbag satellite sensor on the passenger side (SBSR)(US). Here is how I did it:
..Keep in mind, working on a vehicle yourself can be risky in many ways. I am not an expert and this only serves as reference, so work on your vehicle at your risk and costs..

1. Move seat as forward as it will go.
2. Remove negative battery cable (I figured it was a good idea when working with airbag components).
3. Remove main rear speaker cover to reveal 5 phillips-head screws holding panel and cabin upholstery in place.
4. Remove, at least, bottom 3 to allow re-positioning of upholstery lining the cabin
5. Pull back half of the door jam gasket for removal of middle inside panel on frame for passenger door being careful not to break any panel clips hooked to the frame(for further re-positioning of upholstery lining).
6. Working carefully, remove upholstery from below speaker panelling and door frame paneling, pulling it down to the floor behind the seat. This exposes your car's frame and SBSR near the floor to the right of where your seat would normally be.
7. Remove both cables hooked to SBSR using flat screwdriver or knife to compress each clip's safety latch.
8. Remove 3 securing nuts fastening the SBSR to frame.
9. Have sensor tested or replaced.
10. Re-install all nuts, clips, screws, panels, upholstery, and covers to vehicle operating condition.

If you had any airbag indicator lights, replacing the unit won't turn these lights off. You will still need to reset with an INPA or at a trusted shop, but it should at least remove the issue causing the light. If you are experiencing a problematic SBSL, or airbag satellite sensor on the driver side(US), the process should be the same except for the side of the car you are working on. I'll try to upload pictures of the items I have referenced soon for better guidance.

I hope this helps
