Then don't make stupid claims. Not from you, definitely not. You have a history of spouting nonsense.

You don't normally need any equipment to clear a service warning light. In most cases its hold a particular button(s) in while turning the ignition on/off. Google will probably tell you which if the dealer/manual won't.

Example for an astra..

Turn the ignition on, one position before starting engine.

Press MENU button until on the display will appear vehicle information menu.

Rotate the button which has on it two arrows one up one down, is located next to the MENU button, until message Remaining oil life is displayed.

Press and hold button SET/CLR, press brake pedal and hold them for about

15 seconds.

Release SET/CLR button and brake pedal, switch ignition off.

He only asked you to cite the relevant law! The fact that you have been conspicuously unable to do so has not gone unnoticed!

To the OP: looking on YT there one common factor that seems to be responsible in the vast majority of airbag failure warnings and that is insecure connector blocks under the two front seats. The blocks in question are colour coded yellow. Take a close look at 'em, wiggle 'em around a bit and see if the fault clears itself. Airbag warnings are not like maintenance warnings in that you cannot clear them without fixing the underlying fault first. That's bad news if the wiggling doesn't work!

Take the bulb out or cover it. No SRS light is not an MoT failure (at present) A lit SRS light is a fail.

So you claim but you have never shown me to be wrong by posting any substantive links. Just because you or TNP claims someone is wrong doesn't make them wrong, quite the opposite in fact.

Do you trust anyone that posts cr@p like this..

"A very useful tip, thank you. Before fiddling with the connector, you need to leave the car switched off for half an hour to discharge any residual current in the electrics. Otherwise, you might trigger the airbag. "

Maybe someone wants to ask him what this residual electricity is and where it goes after 30 minutes?

You make a stupid claim, it is up to you to back it up, that is how it works.

On the case of an airbag it can give a code indicating the sensor or the problem at hand.

Have you ever heard of a capacitor?

There is a raft of storage devices used in electronic equipment. You should get out of that chair and in the real world some time. It's moved on since valves.

I'd be very surprised if there were any in a car capable of retaining a charge sufficient to trigger an airbag after 1/2 an hour. ;-)

dennis@home submitted this idea :

They use a charged capacitor, in case the 12v supply fails in an accident. It still allows them to fire in the event of the 12v failing.

Resetting things like airbag warnings may not be within the scope of some aftermarket devices. ODB is generally to do with engine emissions, etc.

You will note however that the guidance on the connector was provided by "JL, via email". Not the same person adding the second bit of advice, so the credibility of the latter does not necessarily have a bearing on the former.

@ MrCheerful, genuine question: I thought not only was the light supposed to come on but that there was supposed to be a chart with how long it was supposed to be illuminated during the self test?

Am I mus-remembering again?

certainly, but it is why you wait, just in case.

MrCheerful

there is a chart, yes. but bizarrely, if the light does NOT come on at all, then it is not a failure. If the light does work, then its operation (ie going out appropriately IS tested . This may change in the next few weeks.

I am not sure that the term "roadworthy" is well-defined in law. For instance, while it may be illegal to drive a car which has no MOT, I am less convinced that it is illegal to drive a car with a valid MOT that has a defective airbag warning light, whether or not a new MOT in the currnency of the old has drawn this to your attention. This may well be a matter of fact rather than of dogmatic opinion.

Look up supercaps, they are a large capacitor with a remarkable qualities.

I also think 1/2 an hour is a long time, and indeed suspect it is more likely seconds. However when the consequences of getting something like this wrong, even I would leave and make a hot drink before returning.
