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"
