Abstract
An exhaust gas purification system for an internal combustion engine of a motor vehicle is provided. The system includes a first particulate filter element and a second particulate filter element, which is connected downstream of the first particulate filter element and through which flows the exhaust gas that emanates from the first particulate filter element. The first particulate filter element operates as a system filter and the second particulate filter element operates as a diagnostic filter. A charge of the diagnostic filter can be determined, and the functional capability of the system filter can be deduced based thereon.
