    Once the airbag warning is triggered it won't go off even if the fault is no longer there. It has to be reset via VAGCOM. In the meantime all airbags are deactivated. It's probably just a dirty connection. Get ti reset first and see if it returns

    I think the lot of airbag activations are due to faulty connections to the drivers seat. Moving the seat back and forth can dislodged the connection to the seat airbag.

    So I'd just check that all that is plugged in ok and then, as above, you will need someone with VAG-COM or a dealer to reset the warning lights. Simply correcting a potential wiring problem will not reset the light.

    If it is anything other than a simple wiring fault then VAG-COM should also log the error that caused the warning light to illuminate and provide vital information on what the problem is.

    Early Audi's do not use gold plated connectors under the seat and as such cause high resistance faults.
    Either use a contact cleaner on teh contacts under the seat or remove teh connector and directly solder teh wires together.
    I have done this on my 1998 A4 and the light has not come back on.
    You will need someone with VAGCOM or a dealer to reset the light.
