Ok, this is a strange one but I'll do my best not to confuse everyone. My dad has two C5's - one of which is an estate, now, the estate has had an airbag light problem for a while which we have tried loads of things with - the diagnostic tests say that it's the steering wheel squib - but we have replaced this and re-set the ECU and it's still there, anyway in the neverending quest to rid the air bag light we decided to see if the airbag light would stay on if we put the entire dash in the other C5 - UNFORTUNATELY, now both C5's read the same mileage (the higher of the two (adding about 20K to the other model) obviously it's some sort of anti-fraud thing but is there any way I can get this reset?? and also any ideas regarding the airbag will be greatly received too!!!
