Leerlauf Ruckeln. Bitte um Bewertung MWB 13/18/23

[Translating...]Hallo, habe unter https://community.dieselschrauber.org/en/viewtopic.php?p=138295 Diagramme hochgeladen in denen die Messwertblöcke 13/18/23 bei kaltem/warmen Motor und aktiver/inaktiver Klima gegenübergestellt sind. Ich hoffe, dass man durch die Diagramme eindeutig die Ursache des Defekts (Unrunder Leerlauf) lokalisieren kann.

Danke.

Okay, from what I can see, cylinder 3 consistently has a slightly higher correction amount, but it's still within the tolerance range (+/- 2.8 mg, if I recall correctly). It's no longer possible to determine whether this is due to poor compression or, in part, to partially clogged injector nozzles.

MWB 18 and 23 are normal.

The PDE-Check-MWB should always be logged together with MWB1, so that you can see the current engine speed and (average) injection quantity. The fact that only 2 additional MWB (besides the initial one) are available is simply due to the system's limitations.
