Beschreibung
Zusammenfassung:	A method for execution with an exhaust-gas particle filter which is operated with an exhaust-gas aftertreatment system, wherein the exhaust-gas particle filter has a filter wall along which exhaust gas is conducted for filtering purposes; wherein the method includes a regeneration phase with the steps: a) setting a soot load on the exhaust-gas particle filter, wherein the set soot load effects the formation of a soot layer on ash deposited on the filter wall; and b) subsequently mobilising the deposited ash by burning off the formed soot layer during the course of an active regeneration of the exhaust-gas particle filter.
