Abstract
The invention is directed to a method for detecting and documenting exhaust-gas relevant malfunctions of a vehicle having an internal combustion engine. The method includes the steps of evaluating the operating state of at least one component of the internal combustion engine in a circuit arrangement to delimit faults, which are caused by improper operation of the vehicle, relative to faults based on defects of the vehicle system; and, outputting a fault announcement and storing the fault announcement in a fault memory in dependence upon the operating state of the component.
