    Try pulling apart and cleaning all the connectors, alot of carpet fluff etc over 18 years can eventually get in the plugs ! Also try moving the seat back and forth to see if that triggers the light. Wiring might be getting rubbed/caught near the seat rails.

    I had the light come on in my MY08. The IID Tool identified the fault was the seatbelt pretensioner. It was caused when the seat was moved, and was a wire going into the pretensioner. I zip tied it secure so it didn’t move which fixed the fault.

    I’m thinking it might be caused by movement of the seatbelt stalk. Maybe move and resecure the wire into the seatbelt stork pretensioner.

    Do you have an IID tool?

    Usually on later cars there is a sensor in the seatbelt which advises when the seatbelt is connected.

    If someone sits in the seat and the seatbelt is not connected the warning light shows.

    I know if I put something on the seat of my Jazz that the light illuminates.

    This needs a pressure sensor in the seat base and a sensor in the belt.

    if the belt sensor was crook then what you describe would happen.


    I don't know whether this applies to your older car.

    It could be that the pretensioner has gone out of resistance spec and needs replacing . If the pretensioner is the same as a D2 it has a set resistance which is read by the BCU.
