Do u think my local car garage would find it on there diagnostics??Alittle far for me to come and visit. But I can check it if you want a day out to Birmingham. Usually it does not hold in an in assisted states unless it fails and it takes an ignition off and on the rest. I have seen it before where it sticks in a system power up test and when criteria is reached it continues but this is very unusual and probably degrading to become a hard fault.
