DPF Ash Accumulation
•
The lighter ash is discharged through the exhaust
system; the heavier ash collects in the soot filter.
•
Ash is a residue of the regeneration process. Over
time, the diesel particulate filter accumulates ash
that does not discharge with the engine exhaust.
•
The computer for the engine calculates the amount
of ash accumulated in the DPF.

The fault messages indicate that it is time to
service the DPF.

In addition to the warnings, the computer reduces
