Mach doch erst mal den test mit der Plastikeinkaufstuete.
Bei laufendem Motor die Verschlusskappe vom Oeleinfuellstutzen abnehmen.


This is an important check. Check the oil fill cap for vacuum, for instance by using a small thin plastic bag across the opening. Don't let it get sucked into the engine, as your weekend will probably ruined. If you don't have any crankcase vacuum but pressure instead, this could be related to faulty VCV valves. Patrick C about this: "You can do a quick test on the state of crankcase vacuum by removing the oil filler cap and stretch by two hands a plastic supermarket bag across the opening. The membrane should be seem pulled into the crankcase (but don't let go the bag!) if there is vacuum inside."
