Default HDi cold starting.

Ok, does the 2.0 HDi engine use glowplugs when starting in the cold.
Seems to be statements saying yes and no.

Excellent post Gibbo.

As you can see, the glow plugs are normally used for starting and moreover continue to run after the engine has started.

The light on the dash comes on to ask you to wait only when it is very cold.

It is a common misconception that if the dash light does not come on then the glow plugs are not used.

If you read gibbos post you will also see as soon as the fuel flow increases or the engines revs get to 2k the glowplugs are turned off so start the car plugs may be on as soon as you drive away they go off.

They really do very little their main purpose nowadays is to help regens.
