Tony, the most common fault is the connection in the steering wheel. Have a read of THIS page. Also check any connections under the drivers seat as sometimes the rear seat passengers can dislodge them. Welcome to the site.

Have the same problem. It flickers or constantly lights sometimes. If i hit slightly the dashborad or hit in the area, wehe diagnostic connector located (don't knopw how to name this place) - it dissapears, but then can show up again (on road defects).
I tried to jerk the yellow Airbag connector - no effect. But when I pass my fingers behind the dashboard I could feel some cable of wires. When I was touching this cable, the light flickered and disappeared. I have found the position of cable where airbag light is off, but it continued not long and airbag light became flickering (sometimes) again.
Could it be connector to the dashboard? Or it's most probably a steering connector?

If it comes of again, look carefully at which way round it goes.
One way round it can catch on a lug on the wheel & get levered off when you press the horn.

This evening sit in my car. After some driving the light showed up again! It's not related to turning the steering wheel.
I slightly hit near - it disappears. Hit again - it appears. As like I turning it on and off
Take a look at the picture. The numbers show te strenght I need to aply to make airbag light on/off:
1 - Very-very slight hit is enough to change the light
- the top of torpedo - note that one is far away enough from Airbag module
- the area near the diagnistic connector (there's airbag module behind)
2 - Slight, but with some force to change the light
- the side faces near radio (right and left)
3 - Even hard enough hit may do nothing with light
- the top of steering wheel
- the dashboard face
So what could it be
According to wiring the ABS light is on if there's "+" signal from Airbag Module:
If there were a wire brake between module and dashboard - the light never came up.
So the first supposition is that the "+" signal is always there, but there's wire break somewhere (though i tested socket C470a and C470b - wires are tighten) that disappears on hit and makes light to flash.
BUT: if there's constant failure, why doesn't light flash when i turn the ignition on?
Another supposition is that there's no "+" signal form Airbag module, but when i hit - it appears. So Airbag Module thinks that there's failure in the system.
Could it be bad connection with sensor/airbag?
Anyway - It there's a failure, why the light never flashes when I turn the ignition on?
I'm little stuck. While wirting here I thought out the idea to test: it's possible that on startup the condition of all wires/connectors is non-failed. So I hit the sensible area to make light come up. Then i slightly turn the ignition off (not to make any stress to supposed broken wires) and slightly turn in on - then the light should flash. And even show me the code where the connection is bad. Ha-ha. I'll get it!

Several people have this including me, I think it’s been reported more on the mailing list.
Mine used to go out with an unbelievably light touch on top of the dash.
It tends to only happen in warm weather or once the cabin is hot in winter.
Sometimes my cruise light doesn’t work & I sometimes get the impression the two faults are linked.
I suspect the problem is in the instrument cluster & may even be a fault with the circuitry causing the LED to come on rather than an airbag fault. Not that I’m suggesting it should be ignored 
If I press on the instrument cluster in the area of the light it will often go out/come on

take the instrument cluster out and re-solder the back of it and you should be fine.

Today I got the situation when the light came up again! So i stopped the car. Turned off the ignition. Te I turned it on - and the AirBag lamp showed up and continued lightening. Not flashing.
Oh, it seems the instrument cluster has to be taken out to look into

Had this situation 'very effectively cured before. In my case I cleaned all connectors and receptacles at the back of the instrument cluster and Bingo.
Also cured the spurious and maddening flickering of the 'door-ajar' lamps when the doors were all closed.
Also cured the idiotic readings from my trip computer and buttons not responding.
There must be a lot of dust floating round the back of the cluster probably from a small air leak in the heating ducts.
If you work carefully with the fascia - not breaking it - you can take the instrument cluster out without having to dismount the steering wheel nor its shroud.
YMMV but worked in my case.

Yesterday took out the instrument cluster and resoldered connectors' pins. Going to set it back in the evening.
Anything else I should resolder before fitting it back?

Resoldered connectors on the backside of instrument cluster. Now it seems to work (no airbag flickering seen) !!!  (though I've driven not too much yet)
Moreover, cleaned the air louvres (will create another thread soon on that - there're some problems;) )
What I didn't understand is that I was able somehow to take off the bezel without removing steering (took 3 minutes), but could not set it back not removing steering (took about 10 minutes to realize that I cannot do it) 
PS: the only problem left now is the gearbox... I'm almost glad =)

Only works the way back in when you make sure the steering wheel is in full DOWN and OUT position...
Worked for me...
