    Hi There,

    I've just bought this vehicle and there was no light on or anything. The car has had loads spent on it keeping it in pristine condition so I very much doubt it's a problem thats been hidden.

    I have thoroughly cleaned the passenger side of the vehicle and now I have the Airbag light stay on.

    A Few Questions:

    1.) I have checked all cables under the seat as best I could and all seem to be plugged in, if I fiddled around etc and set off the warning, will the airbag light go off or will it stay on now until reset?

    2.) Does my E39 have an OBD2 port inside the car? If so where would it be?

    3.) will the INPA software be able to reset the airbags or do I need a dedicated tool like the B800?

    Regards

    Jamie

    I have done so much research into where the OBD2 socket would be and it's not there, I've even unscrewed the lower dash cubby hole next to the steering wheel and looked behind it and nothing.

    So I take it I have only got the round connector under the bonnet to use?

    i would say yes to both posts
    There's an alternative. There's always a third way, and it's not a combination of the other two ways. It's a different way

    I see you've made you're decision now lets see you enforce it.

    Hi,
    what I suspect in your case as you mentioned you hoovered your car promptly is that the sensor mat (passenger occupation sensor) in the seat might have cracked and now sensing a fault and that is why the airbag light comes on. The problem with those sensor mats in E46 as well as in E39 is that if you stand on the seat or kneel by trying to reach something or whatever the pressure from the weight applied on the cushion of the seat bends that sensor too hard and that's all it takes for it to brake. It might not be the case but I've seen a lot of these problems over the time I worked at a BMW dealership.
