Could be the glow plug relay mate as soon as the cars warm the glow plug relay should de-erergise, do you have a multimeter? If so then measure the resistance of each glow plug to the engine block they should be approx 2-5 ohms if the are then they are ok.

Be careful a few have snapped theirs and then it is probably a head off job plenty of wd and let it soak for a bit.

Yes be careful with glow plugs, i snapped 2 of mine. Car still starts fine, i have the EML light on for about 5 mins (if that) on first cold start up and then goes out. As the car starts ok it's not an issue at the moment so will save money and see what a garage says, i'm expecting the worst that the head needs to come off so will save and deal with it at a later date.
