I've replaced many bulbs & the warning just goes away, there might be something else wrong.
if your airbag warning light came on I suggest to get it scan, the problem might not go away by just resetting it, my airbag light is on in my 540i, I know it's the passenger buckle, tried erasing it, but it came back as soon as someone used it.
