Claim Text:
1. A method for operating an exhaust gas system of a motor vehicle, the method comprising: passing exhaust gas from an internal combustion engine through an oxidation catalytic converter and a particle filter situated downstream from the oxidation catalytic converter in a direction of flow of the exhaust gas, wherein the particle filter is at least partially provided with a coating that is active for a selective catalytic reduction reaction of nitrogen oxides in the exhaust gas; and regenerating the particle filter to reduce a loading of the particle filter with particles filtered from the exhaust gas, wherein the regeneration of the particle filter is performed as a function of an aging value characterizing an aging condition of the oxidation catalytic converter in such a way that a residual particle loading remains in the particle filter, wherein the residual particle loading corresponds to a loading value greater than a threshold value that is predefined as a function of the aging value.
