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.
