E85 Z4 - Cannot connect to airbag ECU to disable occupancy sensor?

[Jakg]

I've fitted some new (non-BMW) seats to my 2004 E85 Z4 and I have the airbag warning light on.

I'm pretty sure it's because the occupancy sensor is missing, and I want to code it out.



From looking at the E46 posts, it seems simple - connect to the "ABG" module and disable it that way.

The problem is that in each tool I try it in, I hit a problem.



BMW Scanner:

I can see I have a problem (although not what it is)



But when I go to try to recode it, the option is disabled






INPA:

Lists a nice vague error

And lists the SIM / Airbag module

But when you try to do anything, it gives some mismatch error

NCS Expert:

Doesn't even list the ECU at all

Any ideas welcomed.

I'm not sure why the pictures aren't working

Managed to do this.

The E85 uses the same airbag setup as the E60 despite being mechanically more like an E46.

You need to connect to the "Satellite ??? ???? Left / Right" module (I forget the exact name) depending on which side you want (SBSL / SBSR).

From there you need to change the SBSL_SBE or SBSR_SBE parameter.

Clear the fault in the SBSL / SBSR module, and the airbag light on the IKE (instrument cluster) and you should be golden.
