Regeneration of particle filter


In certain driving conditions, the particle filter can not be cleaned automatically, e.g., in continuous city driving. Then this function can be used to force a regeneration of the particle filter. The function cleans the filter from soot particles by increasing the exhaust temperature and thus burn off soot particles. Increase of the exhaust temperature takes place automatically during the regeneration procedure.

Note:

Test conditions:

Procedure:

  1. Start the function.

  2. Confirm with "OK". Regeneration starts with an increase of the engine rpm.

  3. During regeneration a dialogue box shows current values that concern regeneration. The function is done when this can be read from the status for regeneration.

    • Regeneration can be cancelled at any time via the function or by turning off the ignition.

  4. The function is done.

    • If the function fails, check the test conditions and repair any faults.
