•
Since the filter itself creates a certain resistance in the exhaust gas flow, the signal of the
DPF differential pressure sensor is also used to determine the filter condition.

If the value measured by the DPF differential pressure sensor is above a certain limit, the
DPF is recognized as being blocked. Then the PCM stores a corresponding DTC,
illuminates the
MIL
(

ight) and activates the limp home mode.
•
The blocking of the DPF is often as a result of excessive soot emission by the engine
(e.g. due to EGR valve stuck open, leak in the intake-air system etc.) or can be attributed
to multiple failed regeneration processes. To rectify this concern, a manual regeneration
should be carried out using WDS (refer to the section “Control System, Service and
Repair”).
