Lightbulb Grande Punto Airbag Warning Light Staying on Problem

My wife has just bought a 57 Grande Punto 1.2 active 3dr.
We have had it for just over 2 weeks.
When she starts it up first thing in the morning the airbag warning light stays on for 8 mins.
It then goes out. Seems to be ok for the rest of the day.

We took it to the dealer and he claimed there was an error in the system software. He then updated the software. That was on Friday. This morning the same thing happened again.

Is this a common fault?
Is there a known cure for the fault?
I am worried it may leave the airbag disarmed.
I have scanned the forum but dont see any posts with this warning light staying on for a period of time and then going out.

Any assistance would be greatly appreciated.

When the air bag light comes on it has usually picked up a fault in the system. They should hook it up to the examiner and that will tell them what has caused the light to come on.

Ask to see examiner printout for proof airbag update was done & system proxy-aligned afterwards.

Re: Grande Punto Airbag Warning Light Staying on Problem

Thanks for all your responses so far.
Just to confirm for anyone reading this post it is the drivers side airbag.
I am intrigued by your post T14086. Can you tell me what the system proxy is and why it needs to be aligned after the airbag system software update? What does the aligning do?
I suspect that if it is a software glitch that there is a sequence of events which has to be followed and they may be doing this incorrectly.
Does anyone know what the sequence to be followed would be?

Re: Grande Punto Airbag Warning Light Staying on Problem

after the airbag ECU has been software updated it needs proxy-aligned to bring it back onto the CAN system (same as fuel ecu's etc)

the software update (as mentioned in 'known faults' sticky) should cure this fault.

Re: Grande Punto Airbag Warning Light Staying on Problem

A further update. I tried an experiment.
I started the car without sitting on the drivers seat.
Hey Presto the airbag warning light went out with the others.
It would seem to me to indicate that there is a loose connection or a sensor which is faulty in or around the seat.
Can anyone comment if this is likely and where the sensors are located.
Are there any photos on this site of where the sensors are positioned?

under the seat

Then again the only wire on the drivers side on the active is the seat belt reminder wires as the Active doesn't have any seat/side impact bags (unless optional extra? )
