Comparing this with my data, as seen in post 14.11, the 0.13 L oil ash volume cannot correspond to either the calculated 8.33 grams or the measured -0.13 grams. There is definitely at least one sensor that is defective.

STOP.
That has nothing to do with each other!

Or am I misunderstanding something here?

I'm interested in the relationship between the calculated and measured soot values.

Is it an EU6 engine?

The soot level can certainly be slightly negative after a regeneration process. Specifically, the measured value is determined based on the differential pressure.
Most likely, the soot level, which previously drops below zero, triggers the end of the regeneration process.

Yes, I was referring to the ratio of ash volume to ash mass. The values posted so far show a significantly different relationship.
Yes, the data I posted comes from a EU6 CR diesel engine with a storage catalytic converter (without SCR).
