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. 25 minutes and the engine rpm will be increased.
Note:
The exhausts at the tail pipe may reach temperatures of approx. 500 °C.
Test conditions:
Engine on.
Engine temperature above 65 °C.
Vehicle stationary.
Procedure:
Start the function.
Follow the instructions in the program.
The function is done.
If the function fails, check the test conditions and repair any faults.
