Possible cause of fault Possible effects
◆ Diesel particulate fil-
ter overloaded, e.g.
due to excessive
short-distance driving
◆ The load detection
function reported a
soot loading of >
30 g. The engine
runs in limp mode,
and torque is limited
to 120 Nm.
◆ Torque limiting
◆ Regeneration of die-
sel particulate filter
locked
◆ As of a soot loading of
35 g, the diesel partic-
ulate filter must be re-
newed.
◆ No exhaust gas recir-
culation
◆ After the fault has
been rectified, the oil
must be changed.
Fault remedy
– Check diesel particu-
⇒ " Checking
late filter
diesel particulate filter,
engine codes CJDA,
CJDD" on page 460,
– Check diesel particu-
late filter, and note en-
gine code
Emergency regeneration
must be performed on
diesel particulate filter
– An emergency regen-
eration must be per-
formed on diesel par-
ticulate filter, because
the regeneration is
locked. This may be
caused by excessive
short-distance driving,
or it may be a conse-
quential fault (EGR
valve defective; air
mass meter defective;
leak in charge air sys-
tem; pressure differen-
tial sender on diesel
particulate filter defec-
tive). If no emergency
regeneration can be
performed on diesel
particulate filter, it
must be renewed
