Hi there,

Hopefully someone a little more experienced may be able to help, about 3 months ago my focus tdci began getting harder to start from cold but was ok when warm, this gradually declined to needing to turn over for 30-60 secs before it would fire up (crank speed seemed normal) and when it did fire a large cloud of white smoke would exit the exhaust, before running smoothly for the duration of the journey. it then started rough idleing when cold and would occasionally fail to get above 500rpm rendering the throttle pedal useless until it was a little warmer and would return to normal. My local garage have no idea and want to start changing random things on spec which i refuse to do. The self test mode shows no stored codes and there were no nasty knocking noises (DMF) prior to this fault occuring, If anyone has any suggestions i would be very grateful,

Many thanks

Ian
