As per Cummins it can take up to 2.5 hrs
Customer: replied 2 years ago.
What if it's taken almost 4 hours
Expert:  cumminsdr replied 2 years ago.
You may and should have fault codex in the ecm pointing to the cause. It could be a bad after treatment componet ,egr system component ,after treatment injector plugged or damaged. It's really to hard to guess nowadays

Is 900 rpms normal for a parked regen? Do you think the filter might need replacing?
Expert:  cumminsdr replied 2 years ago.
I would have Cummins perform the proper testing on the entire system before spending thousands on replacing the doc or dpf filters. It could be as simple as an exhaust pressure sensor or turbo.
Customer: replied 2 years ago.
So can the above listed reasons cause the parked regen system to stay active with the Amber indicator on even though the dpf doesn't need to regen?
Expert:  cumminsdr replied 2 years ago.
Yes the system thinks it needs a regen or it has not performed a proper regen so it keeps going
