5.4 DPF
The Diesel Particle Filter (DPF) function manages DPF
regeneration, DPF component replacement teach-in, and DPF
teach-in after replacing the engine control module (ECM).
The ECM monitors driving style and selects a suitable time to
employ regeneration. Vehicles driven a lot at idling speed and
low load will attempt to regenerate earlier than vehicles driven
more with higher load and speed. For regeneration to take
place, a prolonged high exhaust temperature must be obtained.
In the event of the car being driven in such ways that
regeneration is not possible, i.e., frequent short journeys, a
diagnostic trouble code will eventually be registered in addition
to the DPF light and “Check Engine” indicators displaying. A
service regeneration can be requested in the workshop using
the diagnostic tool.
DPF regeneration is used to clear PM (Particulate Matter) from
the DPF filter through continuous combustion oxidation mode
(such as high-temperature heating combustion, fuel additive or
catalyst reduce PM ignition combustion) to stabilize the filter
performance.
DPF regeneration may be performed in the following cases:

The exhaust back pressure sensor is replaced.
 The PM trap is removed or replaced.
 The fuel additive nozzle is removed or replaced.

The catalytic oxidizer is removed or replaced.
 The DPF regeneration MIL is on and maintenance is
performed.

The DPF regeneration control module is replaced.
