I started the engine with the drivers door open. The Airbag fault light and warning came on.
Everything else works fine.
Garage put the tester on and the readout was "Side Airbag Intermittant" fault.
Not sure if it was reset , but it displayed and went out as normal for the next 50 or so times the engine was started using the car normally.
Then, talking to a neighbour, I had the door open, and inadvertantly started the engine. Bang, Airbag light came on again.
I believe that the fault trigger is based upon the sequence of events - like the open door and starting the engine.
So, is it possible to reset the light remotely? I am aware of the consequences if there really is an airbag failure, but if it onl;y comes on after a sequence of events and after a garage reset, works as intended - the light comes on and stays on after starting the engine for a couple of seconds before going out. No error message on the display so I presume the initial start up test is ok.
