Glow plug indication light flashes

Remarkably, this problem is often associated with a faulty brake light switch down at the pedal!
It happens on my '97 Sharan from time to time and a tap on the brake pedal with my left foot stopped the glow plug light flashing.

You may need to replace the switch; but I would suggest checking the connecting wires down there first - and get someone to tell you if your brake lights come on when you press the pedal.

Hope this helps you a bit. If it does, a "Fixya" rating would be much appreciated. If it doesn't
help you, I'd be grateful if you didn't bother with a rating at present - they can't be increased later if I do manage to solve your problem! Just come back and tell me what you found. Cheers, D

Hi this can be the engine management light too, the car is telling you there is a problem somewhere, have the car put on a diagnostics reader, Hope this helps

check these 3 things 1. it could be a defective glow plug 2. it could be a defective glow plug harness 3. it could be a defective coolant pre-heat heater glow plugs there are 3 of these located at the coolant inlet top of engine. You'll need a good dvm to check these out, also good to have vag-com scan tool software plugged into the service port for on board scan of the ecm.
