Help Airbag light coming on going over bumps

Hi
Just had my 200 Cup just over a fortnight. On Sunday the check airbag light came on the dash with the spanner sign and the airbag on the rev counter, then went out again.

Now it doesn't happen all the time, if I give the car beans over country roads and hit a few bumps the light comes on, then goes back off.

Car has Recaros, I am thinking loose connection somewhere, airbag ring? anyone had experience of this? Car has 29000 miles on.

Car is still in warranty, I presume the Dealer bods should be able to see a fault code in the ECU to pin point the fault?

Any help appreciated.
 
Check the airbag plugs under the front of the seat, maybe loose or incorrectly connected, disconnect battery, wait 20 mins and unplug and plug back together. I think the plug got a slide on clip fron the side to lock the plugs together.
