SMG specific longitudinal acceleration sensor question

[nextelbuddy]

So I have a current project for an M3 wagon and I'm currently retrofitting the complete SMG system.

Currently, I have extracted all the wiring I need for the SMG system including the SMG body harness connector to the SMG DME. The final three wires in that connector ran into the car all the way to the passenger side under the carpet under the seat to a specific sensor only on SMG car is called the longitudinal acceleration sensor. It's mounted on the chassis facing forward towards the front of the car and is mounted in the same manner as the DSC MK60 yaw sensor on the driver side.


I ended up tossing my parts car and that was the only piece I didn't grab was that sensor

I was able to cross reference that sensor and find out that it's actually used on non-SMG car early MK60 non M cars for the DSC system and that sensor is mounted on the A pillar right above the EWS box area under the dash.

So I was actually able to get a replacement sensor pretty easily locally and confirm the same part number

The problem is now though I don't know how it mounts to the chassis. I don't know if there are studs or bracket that is pre-existing on the chassis or if I need to purchase that bracket to install the sensor

Trying to use real OEM has been really frustrating because I cannot find that sensor in real OEM specific on the SMG car. I can only find it in reference to the early non-M cars and even if you put the part number in, it never shows that it's part of SMG cars. Specifically, it only shows on the non m cars on the A pillar

I did find another post on NAM3forum or someone posted a picture of the same sensor from their SMG car asking what the sensor was and they posted a picture of the part number on it which ends in 95326

https://nam3forum.com/forums/forum/main-forum/e46-2001-2006/194427-passenger-side-acceleration-sensor

So my question is, Is there anybody with an SMG car that has a picture of the passenger side chassis floorboard under the carpet that shows that sensor and how it's mounted?

Or better yet, does anybody happen to have the carpet out on their non-SMG car and can verify if there is a mounting location for a sensor on the passenger side

I wish it wasn't this hard because normally I would just look up the part number for that sensor and see if there's an associated bracket for it and just order the bracket, but I can't find the sensor in real OEM for SMG specifically to do that

Thanks for any help.

Picture from TIS:



Looks like it just mounts directly to the chassis, open end of the bracket pointing up.

I can't help on whether the non-smg cars have mounting provisions for it, but if there's nothing there, you could always add a couple rivnuts and bolt it in.

Ill try to snap some pics later. My car is SMG and has no interior so should be easy to do.

Yeah I used a new TIS site and I saw the same diagram for a sensor. B49, it was just a little hard for me to zoom in considering it looks like it's a scan of a PDF from years ago lol

My main thing was trying to see if BMW did something cool like they sometimes do wear. They have provisions in the same spot across the entire chassis line and some places for dual purpose roles of things. Was kind of hoping that on a non-smg car there would still be some type of provisioning there

Thank you sir. I look forward to that!

See if these photos help, if you need different angles let me know.

Wonderful, thank you very much. Hopefully when I get under the carpet in my E46 late model touring, I might be surprised to see two studs already there so I'll cross my fingers. I know I have those plastic 10mm nuts laying around from something else
