Glow plugs are not going to help once the engine is running
Sorry, Rae, I'm gonna have to cry BS to that.  That era Mundano is common rail, so glow plugs are arguably more important once started than they are in the starting process, particularly in current UK temps.


But, yes, I am more suspicious of injectors on that car, but the glows are an easy first check, and you could be lucky - it's Christmas after all! ;D
                 Fair enough :) too modern for me then ;D

So do the glow plugs stay on once the engine is running? I thought they were purely there to get things warm and aid starting?

Shows what I know!

Presumably the finer injection tolerance requires a post start warm up to ensure a cleaner burn... Aka emissions wank  :-\

As opposed to the traditional let it smoke until it's warmed through  approach.

In the UK, a common rail diesel doesn't really need glow plugs at all, but does reduce cranking times in very cold temps (well, UK idea of very cold), and improves idle and emissions after its started.

Yes, glows stay on after cranking has finished.  There tends to be 3 stages of glow plug control on modern diesels, pre cranking Iif required), cranking (if engine cold) and post cranking (usually a complex algorithm based on fuelling and temps).

You missed the fourth stage: not working properly and causing expensive faults ;D

Seems to have sorted itself out M'Lud.  :y

It started and ran fine today.   :)

I wonder if the Italian tune up it got yesterday helped?  ;D

               That’s why I’ve coupled another battery to my master van to help start it when it’s really cold. I will never try to change the glow plugs in that as I just know they will snap👍
