Abstract

The invention relates to a method for geographically localizing triggers for malfunctions in a motor vehicle, wherein the malfunction of the motor vehicle is detected and an error entry describing the malfunction in an error memory of the motor vehicle is generated, and a geo-position (XY) of the motor vehicle is detected and stored by a localization device of the motor vehicle pp(1). Subsequently, during an error diagnosis of the motor vehicle, the error entry from the error memory of the motor vehicle is read out by an analysis device located outside the motor vehicle and a trigger class (14) describing a trigger of the malfunction is received for the error entry. The geo-position (XY) of the motor vehicle and the malfunction are stored in a corresponding digital map for the trigger class.
