Citroen Relay 2.2hdi starting problems

Post by Tommyboy » 13 Nov 2017, 21:03

Hi All,
I have a Citroen relay 2.2hdi 2010 van that's having trouble starting whilst cold.
My immediate thought is the glow plugs need changing, as as soonit's been running a while and the engine is warm starting again is no problem. However in the mornings I am having to give the plugs 20-30 glows before the engine finally starts. My confusion is that as the engine eventually runs the glows plugs must be doing something! So was thinking the glow plug timer or thermostat could be faulty (not sure which I have)
Any thoughts before I remove the common rail to get at the pesky plugs!?
Cheers

I keep hearing a derv trying to start on Monday mornings! (3 x 30 turns) and I get to thinking if they could start with a plug or two gone ... eventually? the heat must build up at some point? someone will answer our questions :) (I can't tell if this one is mech or electric injection- I suspect electric)

anyway..no help to you Tommy !

my 8 valve old school hdi 2.2 had a failed plug or two when I rebuilt it .. but didn't try and start it before I rebuilt it -in winter..

I would change the plugs and start from there

Glow plugs don't really do much on Hdi engines unless you live in Siberia, it could be that the engine is not turning over fast enough either because the battery or starter motor need replacing, or it could be the pressure regulator on the HD diesel pump.

Yes you are correct peter i forgot about the starter motor problems on the 2.0hdi's - have come across a few poor starting and it was the starter motor not turning the engine fast enough although some have seemed fine buy ear.

Cheers for the replies! I've got a new battery in the last couple of weeks as the other one wouldnt hold its charge any longer then a couple of days so don't think its that! Could you explain a bit more as to why the starter would not work on cold days though? And also pressure regulator, how would I go about determining whether this would be the issue or not?
Thanks again!

The fall off in performance in cold weather is due to thicker engine and gearbox oil causing more drag and if its extremely cold it can affect battery performance but if the starter sounds noticeably slower when cold could be a worn motor.

Check for around 14.4 volts across the battery with the engine running to make sure the alternator is charging properly.
