   so speaking to mr mot tester on this new stupid rule on having to have the airbag light click on then go off for mot time.... how are people doing this as mines taped over at the mo so doesnt see it at all. and pretty sure a resister will just keep it off?

   a working air bag gives a resistance of 1.2 ohms, the control unit looks for this exact resistance on each airbag circuit to turn the light off

   resistors wont just turn the light off completely. I have a 3 or 4 ohm resistor coming off each wire under the carpet under the seat, and the airbag light comes on with the turn of the key, and turns off after a second or so.
   This way your pretensioners are basically by-passed

   if the light doesnt come on with the ignition then go out after a few secs then it will fail

   my pretensioners are pulled in its just the steering wheel airbag i need to sort out so light shows on ignition then turns off after a few seconds so would this work? and how the hell do u solder it all and find what resistors to use?

   has anyone done a guide or how too for wiring these resistors into the steering wheel airbag part as pre tentioners are plugged in

    Means you'll need a 1.2ohms resistor lol

    I have the resistors, how do I do this btw and how do I know which one is the issue other than trial and error?

    you get the resistors from maplins or ebay etc. just ask for a 3ohm resistor.
    you just poke the resistor into the connection block. One leg of the resistor for each terminal in the plug. And solder it/tape it all up. You then do the same for other seat. The car is 'fooled' into thinking the resistors are the pretensioners plugged in when they arent
    Its most likely the plugs or pretensioners on the the seats which are causing the airbag light, rather than the airbag itself.
    i did some trial and error with my pretensioners. So i put a resistor in the first drivers side with the passeneger side plugged in as normal. Turned the car on and airbag light was flashing. So Did exactly the same with the passenger side and the light was still on. Then did both seats and the airbag light turned off.

    can only fnd a 1.8ohm resistor will this do or do i actually need a 1.2resistor

    is this true or just your own opinion on the matter
    my mate old car passed mots without airbags before

    1 resistor for each terminal? so will need 8 in total or am I missing the point here?

    just looking in haynes modding manual think these are what we need...http://www.ebay.co.uk/sch/i.html?_kw...g&_kw=resistor and u solder them into the plug holes or tape them on. so u will need 3 of the ones in the link

    Hmm so what do people do with non airbag aftermarket wheels? Looks like I'll be slipping the guy £20...

    no, one leg of the resistor pokes into each terminal of the plug. The plug /connectors have 2 terminals
    
    resistors have 2 legs
    
    so one resistor per seat

    its most likely a fault with the connector plugs under the seats

    my mot is on thursday, airbag light flashes while driving so will this affect me?
    
    also how do i turn it off as just got tape over it

    wont effect u untill next year as these new rules come into play in april. but by the looks of it u just plug a resistor into the plug and it should work as normal. but waiting for mine to turn up to confirm

    There was a thread on the new MOT's in march..
    
    States that if the car had a airbag as standard, it must be present and working.. If you can't get a friendly MOT'er.. Will have to swap steering wheel's over for mot time.
    
    But the light has to come on with ignition and go off when started, But obviously people with stripped cars etc who have taken airbag ECU out.. Then they will have to wire the airbag light into the oil light, so it comes on with ignition then goes off when started.

    i spoke to my tester yesturday and he said weather airbag is present or not the light just has to come on with ignition and then go out within few econds and it will pass

    if its on all the time due to a fault, look under both seats and there are wires connecting to a small box, make sure the wires are plugged into it and then the light should go off.

    If you have an aftermarket wheel then google max power saxo modifying ebook & download the pdf,instructions for the airbag are on page 122.
    
    Then these of ebay http://www.ebay.co.uk/itm/1-8-ohm-re...item4aaf3742fe

    i have brought these but first few posts someones said u need 1.2 and no one has answered weather 1.8 will work the same
