Just checked the manual. It says "hold the ignition key in position 2 until the indicator light goes out".. The question is, which indicator light as that I cant find which one it is talking about. It goes on to say "in extremely low temperature conditions, the starter motor may have to run for upto 40 seconds"

The only time I can start the engine without any trouble (eg straight away) is if I take the yellow light on the fuel guage as the indicator light..

Depending on the cluster, next to the engine symbol (bottom left), there should be a DDE (Diesel Digial Electronics) symbol, but i dont have that. The manual states that will indicate when the Glow Plugs are warming. However, right near that (to the right), is a light, mine never comes on. Is this the Glow Plug warming light. The manual says nothing about it.
