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. 10 minutes.
Note:
Exhaust temperature is very high during this procedure. Therefore, perform the regeneration outdoors, without connected exhaust hose.
Test conditions:
Engine on.
Engine temperature above 70°C.
Fuel level at least 1/4.
Approved engine oil level.
Parking brake shall be applied.
AC shall be off.
Do not touch any controls or pedals while the function is in progress.
Procedure:
Start the function.
Follow the instructions in the program.
Regeneration takes approx. 10 minutes.
During the regeneration phase, the engine speed is increased to approx. 3,000 rpm.
The function is done.
If the function fails, check the test conditions and repair any faults.
