Seatbelt and Airbag lights on HELP

[StephenVA]

Had this same issue with an E39, I noticed that wiggling the key in the run position would resolve all or some of the failures (Radio displays, four way flashers, turn signals, etc). Rotate key off and back on and some would not appear. All Dignostics pointed to the Ign Sw.

I replaced the T/S SW in approx 1.5 on Sunday morning and all is fine now.
