    Hello I have a 1998 saxo vtr/vts 1.4 8valve
    The problem is that I have the finnish MOT incoming soon and the airbag light does not turn off. When I start the car it flashes for some while and then it just stays on, I've read the fault codes with autocom delphi and it said something along the lines of seatbelt circuit interrupted (sorry for the rough translation it was not worded properly even in finnish)
    Well after doing some digging around this forum I found out that the connector under the seats might be the problem, no problem cut the connector out and soldered the wires together. Still the same problem, okay more digging around
    and I found talk about using resistors to "trick" the airbag ecu. I bought some 2.2Ω resistors plugged them in and surprise surprise the light is still on.
    I tried resetting the codes with the autocom.

    The code:C3A1 seatbelt circuit interrupted
    and a blank code without any numbers or text.

    I'm open to any "illegal" "stupid" ideas. It's not likely that the survival % is going to be high in a saxo anyways only thing is that the airbag light must come on and turn off some time after the car is started

    Classic, I had it some time ago. Check the yellow wire itself, it's most likely broken inside the sleeve and you can't see it.

    Worst case scenario you bypass the seatbelt, but in case of an accident you won't get a working pre-tensioner.

    Yeah I installed some resistors really close to the airbag ecu still the problem persists, even the same with the airbag itself. Well I thought I'll steal the light from the cat light next to the airbag with some jumpers, well worked in for a few hours. and now my tacho, speedo and fuel don't work unless im holding the key in start position. And i just broke my batt negative terminal, I'll have to get a new terminal. MOT due in 13 days, as long as the light lights up and turns off a few seconds after starting I'm good, otherwise a brillian car and low mileage (only 119000km)
