Airbag warning light

[Blooboy]

Hi all,  Corolla airbag warning light on seems to be a common problem.   In nearly all cases it can be attributed to wiring connectors under the front seats, its just a job of taking the connectors apart, spraying some electrics cleaner into the joints and put them together again.   Unfortunately this did not cure my problem, the light is still on.   Even though my car is on an airbag recall list, Mr T cannot even say  what the problem is, as well as there being a 8 month waiting list to have it diagnosed.

Does anyone have come across this problem, maybe give me a few pointers please.

The car is up for MOT in a weeks time and I'm sure it won't go through as it is.

Thank you  in advance, Dee
