S0rry lads for the late reply,full on with work so not getting mush time on the pc,anyway,dropped my avensis tourer back over to my machanic last week to sort out the airbag light,it turned out to be a crash sensor just at the back of the right headlight,my machanic said this controls the airbags in the car if its in a major crash.he orders the part as it was faulty[,he switched over the sensor from the left hand side of the car and it worked,he then put it back on the cumputer and it showed the left hand side sensor was gone,]the sensor arrived the next day and he fitted it and the airbag light went out,so alls good now,thanks for your help..
