hi guys really need some help here ..have 2.0d s40 2005 beautiful motor really love it .... just every now and then i have trouble starting wont fire and wont rev at all and when it does eventually start it plumes out white smoke for a bit the smoke stinks of diesel .. its also abit rough on tick over occasionaly would really be grateful of some advice maybe someone else has been unfortunate enough to have suffered same problem in the past any advice gratefuly recieved ....

May possibly be injector(s) overfuelling ?

turns out it was a faulty egr valve hope this can be of reference to someone in the future ....
