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 l
ight 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.
2. The ECU must be re-adapted when replacing the DPF and when topping
up the fuel additive Eolys.
