Wait, what do you mean the battery's dead?

There is a loom that runs along the crossmember under the rad check that as that has been known to leave lights on, also fires bud

Haven't had any problems with you glow plugs have you. Had similar kind of problems and was the glow plug relay messing about. Mine was a bit more severe though, electrics cut out completely with no warning!

Cheers for the helpful comments guys

Glow plugs were changed when i first got the car back in september and i cant see them messing up that quicky? :/
