Well,i got around to looking into this today.My light came on just before xmas,after being fixed for the 2nd time in 2 yrs.Both times being the module thingy in the steering wheel.Striped the whole airbag & wheel off today.Dismantled & checked everything.Even replaced the conections under the seats with crimped connectors.To my delight,when i started the car,the light went out as normal

.Took it for a drive,within a mile it came on again

.
Apart from taking the dash to bits to check the passenger airbag,i`m now at a loss what to do.With the standard of driving today,it would be nice to have working airbags!
I think i will have to ring the independent garage to have a polite word.I begrudge having to pay another £35 to be told whats wrong.So will see what they can come up with.
