I've got a mondeo ST TDCI and recently its started to smoke (white/light grey) on start up from cold. It clears straight away and doesn't smoke any other time and the car runs fine with no fault codes. Any ideas anyone?

 

My passat tdi does this too, only when weather is cold.

 

Funny you say that, it's been happening since the weather has turn colder.

 

Another Mondeo ST Tdci owner, (well it's my sons) with exactly same symptoms, watching this with interest.

 

Probly I burnt fuel if you turned it over a few times before it fires it will have excess fuel in bores on it will pump a bit of white smoke out while it burns it off

 

Normal on a derv when it is cold. My golf has done it every winter

 

Sounds like normal condensation
