Air bag light

[grannyknot]

I have had an airbag light on between the tach and speedo since I bought the car, I found my way into the body diagnostics and there were the following 4 codes.
93B2 safety battery terminal
93A9 control module fault
93C8 deactivation switch center steering column
93C9 deactivation satellite A pillar left

From some reading up on these I've found that they might not be the problem at all, it could also be anything else in the SRS, the seat belt receiver, the seat occupation sensor or even the front impact sensors.
Do I just start replacing components until it is resolved?
Is there any way of testing without blowing airbags?
Thanks

ISTA can clear airbag fault codes. Somebody probably removed seat or steering wheel while battery was plugged in.

I recall you were playing around with M3 steering wheel. Maybe the airbag in it is not fully compatible?

I ended up not using the M3 wheel but instead found a standard Z4 wheel that uses the original airbag.
