Hi I have a problem with the engine pre heaters on my 1.9TDi Alhambra/Sharan.
I have changed the glowplugs to no avail, I have (at last !) found the fuses and relays and checked these which are ok There is no power to the glowplugs when ignition is turned on although there is power to the relay and low tension fuse feeding the relay.
Is there some sort of inhibitor which is telling the glowplug power supply that they are not needed. A temp. sensor perhaps ?
I can get the car to start immediately if I manually power up the glowplugs from the battery direct.
Any clues or help would be much appreciated.:1zhelp:
