Polo 6R BJ2010 DPF - Fragen

Hallo,

mein Auto hat weniger Leistung. Deswegen habe ich gestern paar Mal direkt hintereinander die DPF Zwangsgeneration gestartet. Leider ist dadurch aber der Filter sogar jedesmal bisschen mehr verstopft. (laut IDE00433-ENG103279 Particle filter: oil ash volume-MASS_ASH_PF) Oder wie interpretiert ihr die Werte?

Die Regeneration habe ich so gestartet:
Security Access
Code eingeben

Dann auf Channel
und dort IDE01637-Service regeneration of particulate filter while driving ausgewählt
als New Value 00 00 und Do It geklickt,
Nachdem Auslesen des Wertes stand er dann auf 00 01 und das Lämpchen im Tacho hat geleuchtet, für ca. 10 Minuten und dann habe ich den Vorgäng immer wieder erneut gestartet

Aber anscheinend reinigt sich der DPF nicht mehr? Mache ich irgendetwas falsch?

Durch Regeneration verringert sich die Rußmenge im DPF und erhöht sich die Ölaschemenge (= nicht verbrennbarer Anteil des Rußes).
Bei Dir erhöht sich der Ascheanteil im Promillebereich, die Rußbeladung ist minimal.
Den Differenzdruck kann man nur bewerten, wenn man den Durchsatz kennt.
Bei Leistungsverlust suchst Du vielleicht besser an anderer Stelle (Ladedruck, Luftdurchsatz, AGR, Raildruck).

Hallo Herbert,

Danke für deine Antwort.

Wenn die Ölaschemenge irgendwann zu groß ist, dann muss eine neuer DPF her? Wann wäre das denn bei dem Auto so weit?

Und was bedeutet es, dass die calculated und measured Werte von " soot mass " sehr stark abweichen?

Komischerweise hat bei mir noch nie diese DPF Spule während der Fahrt aufgeleuchtet, springt die nur an wenn man es erzwingt? War das korrekt, den Wert einfach auf 0 zu schreiben um dies zu erzwingen?

Ist der Wert IDE01407-ENG100958 Particle filter: fuel consumption since last regeneration-FCO_SUM_RGN, sehr genau, weil er aus den Abgasen das verbrannte Öl rückrechnet oder ist das eher ungenau?

Will auch viel nebenbei Lernen, auch wenn ich den DPF jetzt auschließen werde. Bisschen zügiger ging die Fahrt dann schon immer, aber vermutlich weil ja die Abgasrückführung ausgeschaltet wird bei der Regeneration?

Hi Alexander,

Zitat:

Wenn die Ölaschemenge irgendwann zu groß ist, dann muss eine neuer DPF her? Wann wäre das denn bei dem Auto so weit?

sollte bei Deinem Auto noch lange nicht der Fall sein, man kann viel Geld für einen neuen DPF lassen, seinen reinigen lassen oder:

Je nach Kraftstoff-/Ölverbrauch und den genutzten Betriebsmitteln jenseits der 200.000km:
http://community.dieselschrauber.de/viewtopic.php?t=25999
und
http://community.dieselschrauber.de/viewtopic.php?t=20333

Je mehr Asche im DPF, desto größer sind die Differenzdruckwerte. IMHO ist der DPF bei Dir nicht das Problem, um ein Gefühl für Differenzdrücke zu bekommen, siehe:
http://community.dieselschrauber.de/viewtopic.php?t=24222

Dem DPF eine Zwangsregeneration zu verpassen macht bei passenden Betreibsbedingungen, d.h. kein Ultrakurzstreckenverkehr, in den wenigstens Fällen Sinn. Einer wäre, Ausbau des DPF zur Reinigung, was ich an Deiner Stelle aber noch nicht tun würde.

Viele Grüße, Rainer
