Hello,

Last autumn, I replaced the DPF (8V, 103kW) (including Oil).

After 15,000 km, I had to do another oil change because there were about 8.5 liters in the engine!

What could be the causes? Tandem pump, PD seals?

Best regards

So, eine späte Rückmeldung:

PD-Dichtungen und die Tandempumpe habe ich getauscht, waren beide nicht mehr OK.

Jetzt bleibt der Ölstand konstant.


Was ich noch gemacht habe:

Bei diesem hohen Ölstand ist vermutlich immer etwas Öl in den Auspuff gelandet und halt den (eher neuen) DPF belastet, er regenerierte sehr oft und konnte nur bis ca. 25% regenerieren.

Dann habe ich die Aschemasse (war im einstelligen %-Bereich) erhöht auf 30% (was meiner Meinung nach gut hinkommt, wenn der DPF durch das Öl "belastet" wurde)

Nun habe ich seit ein paar tkm Ruhe.

Gruß
