i have just had it off a garage not a ford garage, they said they done a service on it so just. It is perfectly fine when it gets up to temperature. I did have a receipt for some glow plugs for the car when they had it so i am assuming they put new ones in.
Before i had the car they said there was a problem with the egr valve on it so they replaced and put a new one of them on.
It only happens when car is cold.
