Figure 5-9 Sample SAS Function Screen 2
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
after treatment particulate matter sensor regeneration, DPF deep clean regeneration,
after treatment high nitrogen oxide reset, after treatment selective catalytic reduction
system cleaning.
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.
