Engine issue, can anyone help?

If you've got petrol clocks....I'll assume theres no glow plug light on them?? If you're not waiting for the glowplugs first thing in the morning surely it will idle lumpy?

According to my Haynes the glow plugs will only come on when temp reaches 0 degs or below anyway, as above that temperature the HDi'd doesn't need them. So the light hasn't come on, it says it won't unless the plugs come on, but won't come on because temp hasn't dropped that low yet. (Does that even make sense?)

I was hoping the only thing that was petrol was the rev counter, I'll try get a torch in and see if the light exists at all.
