    Trying to get my S3 back on the road and have a MOT on Tuesday. At some point in the cars life i believe the airbag has gone off and the previous owner has just stuffed it back in and put a dab of glue on the flap with the airbag behind.

    after a bit of research i found this: VWVortex.com - Airbag light...how did you trick your ECU?

    so i purchased a 2.7 ohm resistor, just plugged it into the airbag connector, reset the ECU and it doesn't seem to have done the job :sob:

    Does anyone know what the resistance of the airbag in the seat should be and or where i might be going wrong? I'm assuming that the brown wire is an earth, do i need to do anything with this?

    Any help would be appreciated as i NEED to get her back on the road so I can start earning some money again!

    thanks

    b*ll*cks! . . Just went down to maplins and brought a load of resistors to test out, unfortunately at a much lower wattage :banghead: right, looks i'll be back down there tomorrow if they're open. I've also found out I need vcds to reset the airbag light anyway. Thanks for you're precise information :thumbsup:

    you're right, i really should and i probably will at some point. . . But for the moment I just need to get it through an MOT so I can get back to earning some money so i can pay for things like this.

    Anyway, just found out having the air bag light on isn't actually an MOT fail yet!

    Thanks
