Here's the problem, the glow plugs come on, maybe for a short period, maybe for 5 or 6 seconds but that period seems unrelated to the car temp. For example, it has happened that it's really cold but they go off again very quickly (virtually not coming on at all to speak of) so the car wont start and if it does - black smoke!


I can hear the relay (number 103, it clicks out some seconds after the glow plugs lamp) and curtsey lamp brightens when it clicks out. But sometimes the glow plugs appear not to come on at all? I thought this could maybe be the temp sensor (near side of engine block under main rad hose (4 core wire) but strange thing is that the temperature gauge seems all fine?

Any help much appreciated - Cheers - Rich
