E46 M3 Airbag Light won't come on
So I failed the NCT on my airbag light not coming on when the ignition is turned on. I googled a bit and found some folks say it was probably blocked off with tape so I took out the cluster yesterday and cracked it open - no tissue/tape/blocking of any kind. The light doesn't come on and never did, as far as I can remember.
Anybody have some suggested diagnosis steps? I'm just waiting on a cable to fall into my hands
E46 M3 Airbag Light won't come on
Is it coming on when you start the car in the morning or is there a problem all the time?
Was the car turned off and on within 20 seconds?
I had a sublimation fail a few years ago and there was no issue with the bulb.
Iirc it just needed a more patient tester.

It doesn't come on when I start the car, nor does it come on when I turn on the ignition before starting. It doesn't matter if I've left it seconds, hours or days, I've never seen it come on

Yep, doesn't come on. I also broke the two clips when I took off the cluster so there'll be no dash tests again without the cable & software until I fix them

Surely the dash light would work during the test though?

I read the code today with INPA and it gives me:
MRS4
81 Fault lamp (AWL)
Error frequency: 1
Error currently present
Short to ground / (Wiring) break
Error not sporadic
Anybody with some ideas? Google isn't being helpful

Led in the cluster might have been destroyed like I have seen a few times before
