I really should pull it apart one day but just to cover myself I put the code reader in the car for mot day.
Would having the code reader actually help if the light came on when they tested the car?

Although, I presume that you could reset the fault code and take it back 10 mins later to show them that you've 'fixed' the problem and the air bag light is now out - bit like quickly replacing a blown bulb so they can issue the pass certificate

If that's the case, being able to just reset a fault code to extinguish the light without attending to the underlying fault makes that part of the test a bit pointless doesn't it?

Ouch :lol: , the light has only come on once or twice in the last year and it was moving the passenger seat that caused it. I take the reader with me for peace of mind just in case it comes on whilst on route to the mot station although I know it will not do that. I agree fixing it is the correct way forward but I seem to be spending too much time on other projects lately and use the car so little at the moment.

I wasn't criticising you, Jim... when I say it makes that bit of the test a bit pointless, I mean that the 'powers-that-be' haven't really thought this through as all they have done is make the MOT tester look for a lit warning bulb rather than actually check the underlying system and there are a number of ways around this - including removing the offending bulb if it's a car where they're easily accessible

They're wise to the bulb removal thing, warning lights must cycle properly I.e. come on with the ignition and then go off.

There is already a growing trend for things like occupancy sensors to be "fixed" with bypass modules, IMO there's going to be an absolute explosion in gizmos to either fake the operation of the lights or to make the car think things are OK when they're broken. There will be tragic consequences for some unwary used car buyers who have the misfortune to be involved in a smash. :shock:

I understand what you are saying but they did run it through a fault finder and nothing came up. He told me the connector has not been moved for 15 years and a quick plug out and plug back in does the job which it did. He also told me if it becomes regular it could be the seat belt tensioner so I will wait and see if plugging it in and out will sort it otherwise a new tensioner will be ordered.

well, 184 flew through the new test yesterday - no advs either :D

noticed they now have the last 4 odometer readings and (MOT) dates on the certificate too - long overdue probably....
