Glowplug help needed!
 

I have a 1990, 1600Turbo Diesel Type 25 VW Transporter, and have a problem with the glowplugs. When the engine is cold they work fine, and when the engine is hot the warming light doesn't come like the handbook says. But after leaving standing for short lengths of time before the engine gets cold again, I have terrible trouble starting it and the glowplug light still dont come on untill the engine is totaly cold. Please help :confused:
