2.2 dti cold start

[tomo610]

Hi i have a 2.2dti 2003, with the cold weather we are having, car a bit sluggish on start. I have read a thread stating possibly car could do with glowplugs staying on longer and that this can do done by updating ecu software. Any advise would be appreciated

1st thing to do is check glowplugs are ok then battery. Does your glowplug light come on ? If so how long for. Cold starting problems can be a few things and if you read through some of the threads you will see members changing all sorts of things from injector seals to glowplugs so it's a hard one to pinpoint

Do you know when plugs where last changed ?

Glowplugs changed about 12-18 months ago and tested by a mate to see if power going to plugs and the plugs themselves both ok.
If i turn ignition off a couple of times its better but car seems to judder for a couple of seconds.

Ask mate to test them with multimeter set to Ohms they should all be below 1 ohm so 00.5 tell him to earth to battery and place positive ontop of glowplug this will measure resistance if they are ok after that check we can rule them out.

Other things it could be are Temp sensor or glowplug relay

Glowplug resistance and get battery checked and not a visual check either as my battery showed green light but was knackered

Hi Took car in to mates garage today,had battery checked and glowplug resistance both ok .
He had a spare glowplug relay so we swapped them over, so going to see what its like over the next few days.

Its been afew days now since i changed glowplug relay over and havn't really noticed a difference on start up , ( still sluggish and judders abit ).
Also the relay he put on is smaller than the 1 i had on before, does it matter which model relay is on.
