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 can be started first when the engine has reached working temperature and this may take up to 40 minutes.
Note:
Regeneration causes very high exhaust temperatures. The car should be parked outdoors during the process.
Do not touch any pedals during regeneration. Then regeneration finishes immediately but can be restarted during the next ignition cycle.
Test conditions:
Engine on.
Gear in P/N.
Parking brake applied.
Working temperature reached in engine.
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.
