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:
The exhaust temperature is very high during this procedure. Therefore, perform the regeneration outdoors, without connected exhaust hose. The regeneration procedure may take up to 40 minutes.
Test conditions:
Procedure:
  1. Select the function: "Regeneration particle filter".
  2. The following instructions are shown and shall be followed to start regeneration:
  3. During active regeneration raises the engine speed to approx. 1500 rpm and the glow coil in the instrument starts to flash.
  4. If regeneration does not start, turn off the car and check test conditions.
  5. Regeneration status, fill factor particle filter, and temperature are shown during the whole regeneration sequence.
  6. Regeneration in progress can be cancelled by:
  7. The engine rpm returns automatically to idle when regeneration has been completed.
