Hi, sorry for the boring nature of this post but having problems with a 4 year old vectra 2.0DTi where everthing is fine when it's warm, but when cold (below about
20C) it will start briefly, splutter then die, then eventually start after cranking it on the starter for up to around 1 minute and chucking out a load of white smoke. once its started its fine and never cuts out. The glowplug light on the dash comes on for about 1 second I think this is normal?
It is definitely temperature related but not knowing much about diesels not sure what to do. The garage changed the fuel filter a while ago but this obviously didn't help. Could it be something as simple as the glowplugs not heating up? any advice much appreciated before my starter motor packs up.. cheers sam
