Golf glow plug light flashing

Mar 11, 2006 5 Replies

I have noticed that the glow plug light comes on sometimes while driving. It flashes at a regular rate of about one second on, one second off, so its not an intermittent connection. The handbook indicates that this could signal an engine fault condition. Does anyone know what faults this warning indicates?


you'd have to plug it on to diagnostic equipment, but check your brake lights are working as the vw's are dependent on the brake lights/switch for driver info.

Fuel Water seperator full?

Yes, see if it goes out when you press the brake pedal. There were two independent switches on my Golf, and it had gone just enough out of adjustment that the two switches disagreed. Otherwise proper diagnostic equipment is really the only way.

Thanks for that.

I think you could be right as I have noticed that after an application of the brakes the light sometimes stops flashing. Are the switches adjustable?

IIRC the switch isnt adjustable, but the "pin" self adjust's its self when you push the brake pedal down and let it back up again.
