This function cleans soot particles from the particle filter by burning them off using an increase in the exhaust temperature. In certain driving conditions, the particle filter cannot be cleaned automatically, e.g. in continuous city driving. This function is then used to force a regeneration. Regeneration takes around 15 minutes.
Note:
The exhaust temperature is very high during this procedure. Therefore, perform the regeneration outdoors without an exhaust hose connected.
Test conditions:
Engine on.
Engine temperature above 70°C.
Fuel level at least 1/4.
The bonnet (hood) must be open.
If there is a cover over the engine, it must be removed.
No faults in the system.
Soot levels not too high.
Flow resistance through the particle filter not too high.
Approved engine oil level.
Parking brake applied.
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 around 15 minutes.
During the regeneration phase the engine speed is increased to around 3500 rpm.
The function is complete.
If the function fails, check the test conditions and repair any faults.
