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. The function should be run if fault code P2463 is shown. Regeneration takes approx. 30 minutes.
The following conditions prevent the function from starting:
Diesel particle filter not clogged by soot.
Pedal-related failure.
Exhaust temperature wrong.
Low battery voltage.
Low fuel level.
Gear-change detected.
Clutch pedal pressed down.
Accelerator pedal pressed down.
Vehicle speed detected.
Check for fault codes in the engine control unit, erase if fault code is shown.
Note:
Exhaust temperature is very high during this procedure. Therefore, perform the regeneration outdoors, without connected exhaust hose.
Test conditions:
Engine on.
Battery voltage above 12V.
Engine temperature above 65 °C.
Fuel level at least 1/4.
Vehicle stationary.
Procedure:
Start the function.
Follow dialogue instructions.
The function is done.
If the function fails, check the test conditions and repair any faults.
