Same happened to my car some years ago, warning light kept coming on. Dealer said probably the "Clock Spring" was faulty whatever that is. Eventually the Dealer claim they fixed it by replacing this mystery "Clock Spring". Couple hundred dollars! After picking the car up and on the way home, guess what happened.... The bloody warning light came on again! So, back to the Dealer. They had the car for a few days, and eventually replaced the Airbag (In the centre of the steering wheel) Nine Hundred Dollars! On the way home, no, only joking, never did see the warning light again, but I wonder what was the problem really? Now I am gun shy of airbags. Don't like cars with 4, 6 or even 8 airbags. Imagine the cost when they decide to play up? Oh, and I did ask for the old airbag. Still got it at home, don't know what to do with it, can't throw it in the rubbish as the box says it could still go off! Rgds, Ken
