Need help i have a Vauxhall Insignia 2015 1.8 petrol headlamps intermittently go off by themselves i have checked the wiring onto the headlights all the way back to the switch i have then replaced the switch, there was still no joy. out of desperation i booked it into local Vauxhall dealership who had the car for a whole day just to be told there was no fault that they could find. (£75 for the privilege) Has anyone came across this fault and know the solution? I have had the car diagnostic tested with no faults present. have stopped driving the car on the night as it is scary when the fault occurs
