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 - fault code P2463 may be stored in the system when a regeneration needs to be run. Regeneration takes approx. 10 minutes. The cooling fans are on when the function is run and it's normal for some smoke to appear. Do not use any of the car's controls when regeneration is in progress.
Note:
Exhaust temperature is very high during this procedure. Therefore, perform the regeneration outdoors, without connected exhaust hose.
Test conditions:
Engine on.
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.
