Driving
Initiate a forced stationary regeneration as soon as safely possible.
Follow the instructions described in section 'Initiating a forced stationary regeneration'.
The forced stationary regeneration to clean up the soot filter will take on average 10 to
15 minutes. This type of forced regeneration must not be stopped by putting the
'regenerate DPF switch' (located on the control panel) in the 'OFF' position.
CAUTION: If the yellow pop-up of 'Soot filter contaminated' is ignored
and the driver starts to drive away, the red 'STOP' and 'Engine warning'
symbols will be shown. If you continue to drive the vehicle, the
Emission Aftertreatment System will be permanently damaged! Stop
the vehicle as safely as possible and initiate a forced stationary
regeneration. The red warning will stop after forced stationary
regeneration has finished.
The SCR system
The SCR system is used to reduce the level of nitrogen oxides in the exhaust gases.
SCR is an abbreviation of Selective Catalytic Reduction. To reduce the level of nitrogen
oxides in the exhaust gases, AdBlue is injected into the exhaust gases.
The EAS calculates the required amount of AdBlue to inject depending on several
engine parameters and exhaust gas measurements, such as exhaust gas temperature,
nitrogen oxide level and exhaust gas mass flow.
SCR tampering
As the use of AdBlue is important for SCR system operation, penalties are
implemented to make sure that the AdBlue dosing system remains in good working
condition.
These penalties consist of an engine derate and a vehicle speed limit. Both of these
are initiated after a predefined period and triggered by:
– AdBlue consumption – level low/too low/tank empty.
NOTE: Next to the power derate and with a speed limit at the next
warning, driving without AdBlue irreparably damages the AdBlue doser.
– AdBlue quality.
– AdBlue dosing malfunction.
NOTE: It may be a criminal offence to drive the vehicle without using
AdBlue required to reduce pollutant emissions.
7.6 DRIVER PERFORMANCE ASSISTANT (DPA)
The Driver Performance Assistant (DPA) is a feature made possible by all the
electronic monitoring and guard functions of the vehicle. It can help the driver get an
insight into how the vehicle is used.
