    a little while ago ( a year ) i reported on here about the p/s foot well full of water and thanks to this site worked out was the hole under the windscreen leaking water from someone running a amp wire.

    To dry the carpet out i removed the P/s seat ect and since then the airbag light has come on. It was reported here that it happens when i removed the seat and can be cleaned from vag/vcds. i have had a mate who tried to clear it and every few days it keeps coming back on.

    I just took the car for a MOT and they failed it on my airbag light saying on as well as " 2 " screws holding my front reg plate on....

    can anyone help about how to sort out the light? any setting to go in and disable it again, as my mate has now moved to OZ

    otherwise im going to take the bulb out and take it back in a few days

    thanks

    That's a common fault.

    The plug under the drives seat is a bit dodgy at times.
    You can either strip the plug down, clean it all up or remove the plug and solder it all together.
    Just need to get the fault cleared and you're done.

    You can't take the bulb out. I think its a LED and the Airbag light needs to come on and go off again.
    So removing bulb, LED or sticking tape over it wont work.

    The air bag will not go off if you are unplugging it or soldering the two ends together as long as the ignition is off.



    As for the alarm.
    The fault codes for them could have happened at any point and never cleared.

    when you lock the car and central locking kicks in, does the pump in the boot carry on pumping away for long periods of time?

    Sit in the car, lock the car so the alarm activates. wait 30 seconds and then bounce around in side like a loon and see if the alarm goes off.
    The other fault codes look like your interior censors are not working or unplugged.


    This is what the inside of a clock looks like.

    P.S. Can a mod please move this to the 8L section as I feel it would be better suited to that location.
    Thank you.

    If it was plugged in to the air bag plug yeah.
    No idea why anyone would do that or why it would power cause I don't think there is any power going to the air bag until its needed to go bang.

    Could be an airbag fault on that seat & maybe they used a light as the resistance to fool the system into thinking its all ok.

    Fix the fault, not fool the system is the way forward.

    If a plug is yellow 9 times out of 10 its do do with air bags,

    Plug back together and read the codes again and see what the rear fault is.

    yeh your right, those plugs arent compatible.

    Someones changed the seat, and probably fitted an earlier or later one with a differnet plug.

    See if the wiring colors match?

    If they do you can probably just solder the two wires together.

    yep, thats what i thought,

    well there was no airbag light on the car at all untill i took out the seat after the leak

    also i have a new cluster in the car and as soon as that was in i got abs light on, that somehow after a bump has gone gone off for months.


    it would be great if someone had a pic of theirs, as other wise i pain to sort out for mot running out in 4 days

    What concerns me is if that was laying against the carpet & it got so hot, it could of been fairly serious, we'd hope the carpets are retardant.

    Because the airbag ECU looks for a resistance on the wire to satisfy itself that the airbag is present and correct.

    A lamp is nothing more than a resistor.

    It wont have been powered at all, because if it were a real airbag and the car applied power, it would go off!

    Oh sorry, the image looked like it had light on the bulb, its just a reflection of daylight on the glass, silly me, did make me wonder, then again having plugged a bulb into that wiring, you never know what else they may have added lol.

    A capless 501 bulb is the same value roughly as an airbag.

    People have been driving cars without airbags in the past and some people dont want to spend £100's of pounds to put a light out n the dash.

    If you had covered the bulb it wouldn't have been a fail either. All they can do is put it down as an advisory.
