Hi, I recently bought a 2018 855D, it has only done 250h. It has an issue with white smoke on start up. It only lasts for a minute of so. First thought was a glow plug. Found the faulty one and replaced it. Now the engine started clean, then about 15 seconds later it coughs, runs rough and blows white smoke for the next minute before fixing itself and running smoothly. Happens every time the engine is cool. Has me scratching my head. Any thoughts would be helpful.
