White smoke while idling

[dirtyweeally]

Hi there,

So I have a 2004 CDTI with just over 150,000 miles and the car has a fair amount of white smoke while idling. It used to just be when the car is cold but does it all the time since my turbo started making a loud whistling noise.

How would I check what is wrong and/or what needs to be repaired/replaced?

Cheers in advance for any help.

Well I would start with a turbo mate.. is it losing oil too? Is it losing any coolant?

Not noticed any oil loss or coolant, just the fairly loud turbo whistle as it spins up.

Whistle is probably normal, but if it's more of a whine then that's not a good sign.

Are there any running issues? Missing, hesitation, lack of power, drop in economy etc?

There is a lack of power around 2000rpm. As for economy I don't drive the car a huge amount anymore or for long distances so I can't really tell.

The car sometimes shakes around 45-55mph, but I've read that that is probably caused by the drive shafts.

Could be a number of things but really it needs a full and deep diagnostic session. Where are you located?
