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. Regeneration takes approx. 20 minutes.
Note:
Exhaust temperature is very high during this procedure. Therefore, perform regeneration outdoors without connected exhaust hose, with open hood, and set the passenger compartment fan to full speed and max. heat.
Test conditions:
Engine on.
Engine temperature above 75 °C.
Fuel level at least 1/4.
Procedure:
Start the function.
Follow the instructions in the programme.
The function is done.
If the function fails, check the test conditions and repair any faults.
