Missing airbag warning light and the MOT test - jonny10buds

A definative answer please, will an inopperative air bag light fail the MOT test? I've asked two MOT testers in the last 12 hours, one said a lit light OR a missing light (bulb taken out) is a fail, the other said a lit light is a fail but a missing light is an advisory only. Does that mean I can take the bulb out and pass the MOT with an advisory? Thanks

I can't give an answer, but it is an interesting question, as it is increasingly these peripheral add-on bits that can send a good car to the scrapper before its time.

I do know about ABS. A car originally fitted with ABS must flash a signal to say it's working when the engine is started, and no lights should come on for the duration of the MOT test.

I'd presume that's the same for airbags.

You can remove the ABS completely, ie the pump and the electronic unit, and then pass the MOT without ABS.

I don't know if you could pull this trick with airbags. Something tells me that if they were originally fitted, they must still appear to work.

No,but find out were the second MOT tester works and take your car there.

According to the MOT uk site: A Supplementary Restraint System (SRS) malfunction indicator lamp:

. inoperative or

. indicating a system malfunction.

is a fail

I'll report on the outcome, presumably when the tester tries to put the advise in the system it won't allow him as this seems to be done from a pre-populated list, one would assume that VOSA will have removed the airbag light options from the list of possible advisories.

Failure of a seatelt which brings on the warning light is normally the passengar seat sensor mat or the connections

It was on my Nissan, but I still had to pay a main dealer to put the light out after the connection was made good.

This is still a matter for debate amongst MOT testers but it I suggest the matter is clear.

The relevant section of the MOT Testing Manual as shown on the VOSA website is here. As you can see there are two reasons for failure (RFRs) relevant to airbags:

  1. airbag obviously missing or defective
  2. SRS malfunction indicator lamp indicating a malfunction

Some MOT testers are saying that if an airbag lamp is inoperable (never lights up at all, even when ignition first turned on) then this is an RFR, but in “Special Notice 01-2013” issued by VOSA to MOT test centres in March 2013 this was specifically excluded and removed from the manual:

  • “Section 5.4, RFR 2 – SRS warning lamp inoperative has been deleted.”

This was also stated in an email from VOSA before the changes came in, as reported on the Pistonheads forum:

  • “In respect of the SRS (Supplementary Restraint System) warning lamp; a vehicle will fail if this lamp indicates an SRS system malfunction. However, there will be no MOT requirement for the lamp to actually work once these changes become 'live'.”

So whilst driving a car with possibly faulty airbags is far from ideal, an inoperative airbag light should NOT fail the MOT (refer your MOT garage to VOSA if they think otherwise). This will at least keep your car legal while you investigate and repair the light, and any faults it might indicate.

So you're effectively saying that if a car fails its MOT on the SRS light being illuminated, then removing the bulb will let it pass?

That would appear to be so!

Alternatively, you could just get the fault fixed !

It really bugs me the mentality of people who just want their car to pass the MOT by disabling this, removing that etc. Get it fixed so you know the car is safe and will help protect you and your passengers in case of an accident. It's a shame the MOT is hobbled by the stupid regulations they have to adhere to, and pass some cars that really should be taken off the road.

No airbag, crash, someone injured and their airbag not working = invalid insurance.

(And rightly too)

Missing airbag warning light and the MOT test - The-Mechanic

Or, crash, faulty airbag = life changing injuries / loss of life, invalid insurance, court case, large fine and / or prison, live with the Consequence's for the rest of your life !!!!

Makes it all worthwhile doesn't it ?

My Berlingo has a key switch to manually turn the passenger airbag off.

I don't see the difference between forgetting to reset and having a duff airbag - at crunch time nothing will happen.

I wouldn't have phrased it the same way but I find myself agreeing with Steve76, some very sanctimonious posters on here tonight.

If my airbag (driver's) didn't work, could not care less. My motorbike doesn't have seat belts, ABS, or air bags.

True to a point.

When using a rear facing baby seat activation of the airbag can kill the child. The passenger airbag switch is there for the specific purpose of disabling it while a child sest is in use.

Is there any other reason to use it?

Nope - I'm just saying I would not be suprised if there are cars out there with the passenger airbag permanently switched off.

Missing airbag warning light and the MOT test - The-Mechanic

Yes there probably are plenty of cars out there that have the passenger airbag disabled with the inhibitor switch, but surely that's different to having a car with a known faulty one ?

Let's say you're driving along with your warning light on, blissfully aware of the fault. You hit a particularly big pothole and bang, the airbag deploys. Sure it's improbable that could happen, but not impossible as you're not sure what exactly the fault is as you haven't had the time/money to get it looked at or just not that bothered as it's "not that important"

You swerve across into the oncoming traffic and……… you get the picture.

If the airbag has been switched off by means of the installed inhibitor, it won't go off which is a totally different matter. I don't know how the law would deal with that situation, but I'm sure they'd go all out to prosecute in the case of a faulty one.

And surely that's the point. When you drive on the roads you have to adhere to the road traffic laws which are different to what happens in the MOT test centre. Your car can still pass the MOT, but the police can prosecute for tinted windows, noisy exhausts etc that can only be advised on the test.

Is there any other reason to use it?

Yes there is other reasons to use it - I deactivated the passenger side once when I was moving a large wardrobe. The front seat was wound down so it was touching the airbag compartment and then it had the wardrobe on top of it.

I considered that if the airbag did fire it could potentially send the wardrobe and seat flying up in the air and either out the back window or somewhere else.

So there is other times when you need to consider disabling an airbag, especially if you put something on top of it

This guy only puts a toy spider on top and it takes the legs off a fluffy toy, can you imagine if that had been something quite heavy and it had flown into the bag of the car and hit someone?

Btw very important thing to remember when you rest things like books and stuff on the dashboard, it it's on that airbag compartment it has the potential to become a life threatening missile if the airbag goes off..

The airbag light is only a fail after March, up till now it's just an advisory, so I'd get your car in for MOT before March then you have a whole 12 months to sort it!

And according to the rules the airbag light must briefly illuminate (when it does the system check) and then go out, If it doesn't come on at all and it's present or it comes on and stays on then it's a fail.

Only one problem with this is where do things like modified vehicles that have had the airbag system removed fit into this, or people with medical conditions that require the airbag to be disabled.
