(T) Airbag sensor strange diagnosis

I've just had my car read for fault codes realating to airbag fault. As I have tried all normal methods and can't get rid of the darn thing. Have been told that it is the clock spring in the steering coloum that is causing the fault. Has anyone ever came across this and knows what would need to be done to fix it.

Thanks in advance

Yes, it is possible for them to fail. Scrap yard is probably the cheapest place to get one to replace it. I am sure they are expensive at a dealer.
