[Warning Light] engine management light

[1982wozza]

Hello everyone need some help here, ive got a 2004 berlingo 2.0hdi, the problem is my glow plug light is intermittent when it comes on its very brief and after a few seconds the eml (engine management light) comes on but after about a mile or so of driving the eml goes out and its fine, but on the other hand when the glow plug light doesn't come on the eml comes on and stays on and only goes out when the engine is up to temp and I turn van off and on again? Any ideas as I find this very strange and don't know where to start first.

Many Thanks

Warren

The glowplug light on the hdi only works at zero degrees and below. At zero it comes on for only one second -5 is about 5 seconds and -10 about ten seconds. It's probably not related to EML.
