DPF Service
The DPF function allows you to carry out numerous functions to the Diesel
Particulate Filter system without having to send your car to a main dealer.
The tool will manage DPF regeneration, DPF component replacement
teach-in and DPF teach-in after replacing the engine control unit.
ECM monitors driving style and selects a suitable time to employ
regeneration. Cars driven a lot at idling speed and low load will attempt to
regenerate earlier than cars driven more with high load and high speed. In
order for regeneration to take place, a prolonged high exhaust temperature
must be obtained.
In the event of the car being driven in such a way that regeneration is not
possible, i.e. frequent short journeys, a diagnostic trouble code will
eventually be registered, DPF light and “Check Engine” indicator comes on.
A service regeneration can be requested in the workshop, using the
diagnostic tool.
Before carrying out a forced DPF regeneration using the tool, check the
following items:
The fuel light is not on.
No DPF-relevant faults stored in system.
The vehicle has the correct spec engine oil.
The oil for diesel is not contaminated.
IMPORTANT
Before diagnosing a problem vehicle and attempting to perform an
emergency regeneration, it is important to obtain a full diagnostic log and
read out relevant measured value blocks.
NOTE
1. The DPF will not regenerate if the engine management light is on, or
there is a faulty EGR valve.
