Smoke(oil) when pulling off - UPDATE 4 FIXED!!!
« on: August 29, 2012, 02:39:05 pm »
Hi all, need to pick some brains.  

Last night i noticed when I was pulling off from lights, traffic etc that quite a lot of white/very light grey smoke was coming out the back, once I get going and even if i put my foot down it stops, not even much black smoke which is what i would expect from a diesel.  So it seems that if i'm sitting there idling for a few seconds it building up something.

No warning lights, not noticing any lumpyness or anything wrong with the engine.  Turbo is only about a year old but it is due a service.

Any ideas peeps?

White smoke could be unburnt diesel as well. When glow plugs last been changed?

I don't know if they have, not since I have owned it which is almost 2 years.  Is it an easy job?

I have no idea what the inter cooler pipes look like or how to discontent them to check for oil.

Should I just get it booked in asap?

glow plugs usually only used when engine cold on pre-glow cycle to warm combustion chamber...after that they dont work...

could also be a clogged/oily intake manifold...

whats your mileage?

Possibly coolant leaking into EGR system through the EGR cooler, common problem.

Grey (usually dark) is fuel vapour

I have also noticed that it doesn't happen when I first start the car, but after a couple of minutes.  Does this help any further?

I agree oil is blue smoke. White smoke is usually water.

If it is a coolant leak, how serious is it?

it isn't necessarily going to be anything serious, if it is only on pull away i would suggest it is a small drip/leak as it would pool while there is no load then not have enough to be noticed on routine driving

i wouldnt panic about it too much, chances are it will be something small and easy to fix

I had white smoke on start up or idle on my TDI Passat, changing glow plugs resolved problem. I even remember fitting first cheap aftermarket glow plugs, which did not help, after fitting genuine ones, smoke on start up and idle stopped.
