Hello,
Check the see-through fuel lines for any air bubbles. If there are, some o-rings or fuel filter or fuel lines from the tank are letting the air in. If the lines are perfect, next likely cause is one of the injectors leaking fuel into return too much. I suggest to have them checked at Bosch Diesel service center. They can rebuild them if found faulty.'

Stan
