Soot loading of diesel
particulate filter
Soot threshold 2 excee-
ded
â—† Diesel particulate fil-
ter overloaded, e.g.
due to excessive
short-distance driving
â—† The system was in
thermal management
mode for longer than
for more than 100 op-
erating hours, or the
operating hour ratio
between normal
mode and thermal
management mode is
higher than 25% (as
of 25 operating hours
in thermal manage-
ment mode after last
service regeneration)
â—† This fault path is used
for indicating an ex-
cessive soot loading
of the diesel particu-
late filter. The counter
in the diagnosis ex-
tract describes, how
often there was a die-
sel particulate filter
loading > 2nd alarm
threshold (soot load-
ing of 26 g). After the
work day has been
completed, a service
regeneration must be
performed on the die-
sel particulate filter.
â—† After the service re-
generation, the en-
gine oil must be
changed. There may
be a fault in the fol-
lowing components:
EGR cooler, air mass
meter, turbocharger/
charge pressure, in-
jection quantities, in-
jectors (IMA-code),
air filter, leak in
charge air system,
pressure differential
sender with hoses.
