Regeneration of particle filter


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. This only has to be done if the particle filter's degree of filling is more than 15% and no regeneration has been run automatically.

A regeneration in progress is indicated in the instrument panel with the control light for particle filter being lit.

Note:
