Air Bag light flashing
Discussion
A reset will enable the light to be disengaged if there is a problematic area on the system diagnostics on the vehicle will reveal the troubled item(s)
Where are you located? I can put you in touch with someone that can run diagnostics and reset if your in Surrey Hampshire Berkshire.

Had something similar on a VW,placed a heavy parcel on the back seat,seat belt not in use,got a flashing light for the airbag.
Thinking if I took the parcel out and ignition key out things would be back to normal,but no,had to go to VW to reset,although vagcom reported no problems at all.

It shouldn't be too hard to reset, I've found steps online that should do the trick.
I'm wondering though if the belt pre-tensioners did go off, do they need looking at before the light is reset - is it something to worry about or nothing major?
Netherfield, do you know if VW simply resetted it or if they did some checks/resetting of the actual seat belt system?

Vag-Com doesn't scan air bag modules unless you specifically ask it to and you have to be careful about doing so as just scanning some airbag modules for error codes can brick them which means you will need a new physical module or a air bag specialist to flash the module back to life.I think the issue only affects 2000-2002 VAG car's so it really depends on the year if its safe or not, but you're best leaving air bags to the pro's ( main dealers + pro's very rarely turn up in the same sentence )
EDIT:
The dodgy module is 6Q0-909-605-A

How old is the car?
Iirc, Nissan specify a check of the airbags and associated circuitry at ten years vehicle age.
Edit, sometimes this can be due to connectors in the system, such that a disconnect and several reconnects to "clean" the contacts might help.
DISCLAIMER, airbag wiring is identified by yellow wrapping and should not be interferred with unless you are technically competent and understand the procedures involved.

It's 5 years old so that's unlikely.Iirc, Nissan specify a check of the airbags and associated circuitry at ten years vehicle age.
Your "testing" the ABS should have nothing to do with the airbags system.
Just constantly resetting the light will not resolve the problem.

In fairness the light was on only once before when I bought the car. Apparently the cable for the airbags could have been nudged when the car was being cleaned before it was sold and the light won't go off once it's come on until it's been reset.
So I don't think there's a recurring problem as such, because it's been fine since the initial issue when I got the car.

Could you tell me a bit about pre-tensioners? They tighten the belt under sharp braking, right? To use simple language, do they 'loosen' on their own or do I need technicians to do this? In other words, if they did fire, would i need to get a technician to reset them before they work again?

Nope, pretensioners work in conjunction with the airbags, they are actuated by a small explosive charge just before airbags deploy to tighten the seatbelts and restrain the occupants to help minimise any harm from airbag deployment.In fairness the light was on only once before when I bought the car.

Sharp braking will not do this.
If they have fired, it would be apparent and new ones are needed, however the airbags would also have fired and that would be visible.
The airbag light should come on with ignition on and after system check, go out.
Anyway, I think you need to get this checked by a competent Nissan dealer.

Does depend really. I have a feeling some cars are designed to fire the pretensioners if you do an emergency stop from massive speeds, because the engineers figure the only time such a thing will happen is when there's about to be a crash.
They wouldn't, that would be very expensive! How many times have you had to slam on because someone pulled out on you yet not hit them? If everytime you did that the pre-tensioners went off you, and everyone else, would be very poor people!The computer in the car can detect when a crash happens (sensors in the wings and arse of the car usually) and, in less than a second, fire, well before the force of the impact is even being felt by your body yet.
