Order the KKL lead with the 3 adaptors, took a while (10 minutes) to work out the drivers and how to chose the correct com port but once I had done that it was really easy as soon as I picked the second one on the list of air bag controllers, notice on the glove box was a wire close to the top of the glove box that may have been being interfered with when the glove box was full, about the same time the light came on. Thanks for all the help everyone, was easy as soon as you knew what to do, especially as this was probably the only thing stopping the car passing the MOT
