DPF / FAP stands for Diesel Particulate Filter.
It is designed to capture soot particles produced by diesel combustion.
Modern diesel vehicles periodically perform regeneration to reduce the accumulated soot inside the
filter.
For example, a vehicle that is used mainly for short urban trips may struggle to complete regeneration
under suitable conditions.
Over time, this can lead to:
increased soot load,
high exhaust back pressure,
warning lights,
reduced performance,
DPF-related fault codes.
What does the DPF module do?
The DPF module is used to work with the relevant DPF control strategies in supported ECUs and
software versions.
It is primarily associated with diesel vehicles.
Petrol vehicles use a different type of particulate filter, generally referred to as GPF or OPF.
