hi all , my airbag warning light is on all the time on my 172 because I have no airbag in the drivers seat. I have just realised it will fail the mot at the end of next month. can I put a resistor in the wiring , if I do this do I need to disable the battery while I am doing it. also there is a microswitch just laying on the floor of the car ( attached to wires ) can any one tell me what this does and what I should do with it. any help will be appreciated very much. many thanks jim
