This function cleans the particle filter from soot particles by burning them off using an increase in the exhaust temperature. In certain driving conditions, the particle filter can not be cleaned automatically, e.g., in continuous city driving. Then this function is used to force a regeneration.
Note:
Exhaust temperature is very high during this procedure. Therefore, perform the regeneration outdoors, without connected exhaust hose.
Due to the risk of fire, regeneration should not be performed if the soot quantity is above the limit value.
The regeneration procedure may take up to 40 minutes.
Regeneration in progress can be cancelled by:
Affecting brake pedal or clutch pedal.
Turning off engine.
Any test condition not being met.
The cancel button in the function is activated.
Test conditions:
Engine idling.
Fuel level at least 1/4.
Gear selector in position P.
Parking brake applied.
Engine hood closed.
Correctly installed and working differential pressure sensor.
Procedure:
Start the function.
A dialogue box shows current soot quantity in the particle filter + limit value for regeneration.
Criteria for successful start of regeneration are shown with current reference values.
Follow additional instructions shown on the screen to start regeneration.
An active regeneration is indicated by the engine rpm increasing to approx. 1,500 rpm.
If regeneration does not start, exit the function, re-start the car, and check test conditions.
The engine rpm returns automatically to idle when regeneration has been completed.
The function is done.
