What fuel have you been using in your common rail/diesel engines.
Since the purchase of my Patrol, this year, I have been using 500ppm. This caused a few stoppages. When the car stops, I then had to pump the rubber (don't know the technical name, so attached a pic) several times and then the engine starts.
But after switching over to 50ppm, never had any problems.
