spoke to my MOT tester and he showed me the list. It says that you will fail if its 'obvious' that the airbag is missing. He read that as - if you have a non air bag steering wheel and no warning light on dash - then its not obvious and you will pass.
hence why my AirBag light has now mysteriously dissapeared!
Out of interest have you made yours disappear completely and if so how did you do it??hence why my AirBag light has now mysteriously dissapeared!

Took the dash apart and covered the led - but kinda wish I'd gone the easier route of just plugging a resisitor across the 2 airbag wires. Not sure what value it would need - probably varies between manufacturers anyway.s express said:

Just thought - when the ecu goes through its checks, the airbag light illuminates, then goes out when it knows there's no faults. So, if you just put a resistor in, then the airbag light will still illuminate with ignition before going out. This will tell the tester that there should be an airbag present - therefore, surely the best method is just to remove (or cover up) the airbag bulb/led????

You need to find yourself a friendlier MOT tester!s express said:

Not sure what value it would need - probably varies between manufacturers anyway.Disconnecting the airbag ecu (on most cars) results in the light being on all the time. Very often if you look into the loom multiplug you will see a spring-loaded metal strip which contacts two pins together in the plug when it is is disconnected from the ecu, bending the strip back may turn the light off. On later models it is often done via coded signal or CanBus in which case it's a lot harder to cheat and tape over the led (where possible) becomes a good option.
I've just spent half an hour on the MOT computer trying to find the failure section for an airbag light not working or missing, I've come home and found out that some of the new regs don't come into force until May. It's bloody annoying as it shows as a failure in the testers manual but there's no provision for failure on the computer. So where possible get your cars done before April/May and it may give you an extra year's grace.

Thanks, useful information that!s express said:

Like you say in other post you don't really want the light coming on at all,even for a second or so as it obviously suggests an airbag is present.I was basically thinking of getting to led in dash and removing it or breaking it but am concerned as to whether it will cause any other electrical type issues/problems with the instrument panel.I basically don't want to end up messing anything else up by doing it.
Your idea of leaving it working but covering it up might be a safer way of doing it actually.Did you use black tape or some black sealant or something similar?

No, this was my point above, the car I tested today had airbags but the light didn't work at all. When you log cars on you get a print out with the cars details plus the sequence the ABS and now SRS warning lamps work. If they don't illuminate in the first place then it's a fail just the same as if it doesn't extinguish when it's supposed to, or it will be after April.I was basically thinking of getting to led in dash and removing it or breaking it but am concerned as to whether it will cause any other electrical type issues/problems with the instrument panel.I basically don't want to end up messing anything else up by doing it.

One of the other testers I was discussing this with today said "how do I know it has airbags" well Sherlock the fact it had SRS airbag written on the steering wheel and passenger side dash is a good indication.

In my case [totally except either way need a very "friendly" tester!] the airbags and all wiring are removed plus i have after market steering wheel.So i am working on basis there are seemingly no airbags present in car but any light on dash gives the game away,hence wanting to do away with it.You and i know [hence "friendly" tester quote] that realistically they would know that originally this car would have had bags [05 LCR] but are you also saying the mot computer will point this out to the tester,making it impossible to ignore by saying this car should have them? If this is the case all us with road going track cars in a similar state are totally fu**ed after April,friendly tester or not

Out of interest do you know how you get all the needles inc.base part off the instrument panel dials as it makes access to leds easier.Do they just pull/prise off? as i have tried this but they don't want to move.I'm reluctant to force them without knowing for sure in case i break them.Appreciate if yourself or anyone else knows the definite answer to this.Rgm racer said:

With the ABS, the print out often says something along the lines of "ABS (if fitted)will extinguish etc etc" but on newer models it'll be certain that ABS is fitted so there's no get out. Today's car was an R reg modded Seat GTI and the printout gave the sequence for the SRS light with no maybes about it, that's why I wasted my time looking for it on the VTS device. So we'll get a print out which will confirm the SRS sequence and part of the fail is that if that any component is missing it's a fail.
