ZD30 CRD Cold Start Issue with white smoke

[Flex]

Now the mornings are getting cold I'm am having a issue starting my ZD30 CRD (2008 GU 6) It takes around 4-6 seconds of cranking to start the motor. Then when it does start there is a burst of white smoke (misty in appearance). After it starts everything is normal. Warm/ Hot start has no issues. Any clues?

Knackered glow plugs?

A few things I would do is clean the Maf sensor, clean the air filter.
Run some injector cleaner next tank full of diesel.
Sounds to me like battery on its way out, only because you say its only happened since its been cold
Time will tell I suppose

x2 on battery on way out

more on the battery does it sound slow when it cranks or fast like a new battery??
If it is your battery and you replace it don't forget to use scourer on the terminal posts
and inside connectors
what side of Melb are you on?

Thanks everyone for your responses. I'll try the MAF/ air cleaner on the weekend.

Do the CRD run glow plugs? How do you check if they are running on start up?

It's not slow when cranking, sounds normal speed. I'm located North-East Melbourne

G'day Flex,
yes, it has glows. The 'spiral' white dash light indicates it's on when starting.
I believe if the battery's cactus, if you put a multi-meter across the terminals whilst someone cranks the motor (when cold ) you'll get a huge voltage drop regardless of whether it shows 12V plus or not.
A good battery will drop but not much below 12V, I think. Might check mine tomorrow AM after a 9oC night.
Luck,
Col
Guessing the white smoke is simply fuel unburnt whilst cranking.

This morning was a cold one (4 degrees C) and the motor took around 4 secs to start with a puff of white misty smoke just after starting. I notice that the glow plug light came on for like half a second max. Is this normal? or should it stay on for longer?

My crd glow plug light stays on for 2-3 seconds on mornings like this. Then it starts no dramas, no cranking, just fires up within the first few turns.

Not sure about the CRD'S but with the di's, the light turning off on the dash doesn't mean the glow plugs are off. The glow plugs actually stay on for a few minutes after the car has started.
