i had same prob on my cavvy when it was 3 years old!.i just removed the wee bulb out from behind the dash.no further probs.(vauxhall told me it would need to go on their computer as it was a "sensor" problem, but assured me the airbag would NOT deploy)car is now 13 years old and ive had no bother with my solution.(a bit of an arse to get the dash off though!)
