The smoke is not white but it smells like unburnt diesel not oil :/ After a couple of minutes the smoke clears and it runs perfect. I've asked a mechanic and he thinks a faulty injector, but hes not sure. The turbo is perfect and when its warmed up its a flying machine.The engine temperature is normal and there is no oil and water mixing. When it starts its running on 3 cylinders then the 4th one kicks in... Weird one for you tech heads :)

I've just bought a 2006 C4 1.6 hdi and when you start it from cold it only fires or three cylinders and smokes a lot. after a couple of minutes the fourth cylinder springs into life and its perfect. I've taken the injection connector off when i've just started it and it makes no difference then when you put it back on, after a couple of minutes it starts working proper. It seems like theres some electrical problem but i've tested it and theres power going to the injector. Could it be the injector is playing up???
