    Hi all, I parked the car and turned the ignition off. The wife remained in the passenger seat and when I returned and started the car the air bag light flashed once and stayed on. Now every time I drive the car the same thing happens.
    I have looked under the passenger seat and I notice that there was a blue and white wire coming from under the seat that have been cut. There is a black box with a blue and white wire coming from it attaching to a blue and white wires by a diy connection block which is connected to another box which has wires connected from the other side of it to under the chair. The blue wire has come away from the diy connection - however even when I connect this wire back again the light is still on.
    What are these wires from under the seat for?

    Reconnect the wire and reset airbag. Or get someone to reset it for you

    You need a reset tool. If you have a good mechanic, have a word they may do it for a drink.

    should of expanded on my original reply....

    sounds like a previous owner has fitted a bypass kit for a dodgy passenger seat sensor mat....
    the bypass kit basically tells the airbag system someone is sat in that seat and in the event of a crash the passenger airbag will deploy eben if noone is sat in the seat. they are only cheap on ebay (but not reccomended by some). you could either replace the sensor mat in the seat and restore the wiring, which is v fiddly or fit another working bypass.

    assuming this is the fault causing your airbag light of course...
