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-
