1. A method for wear diagnosis of a motor vehicle, comprising: detecting driving events and driving conditions occurring during the driving operation of the motor vehicle, assigning each of the detected driving events and driving conditions to a wear index value using a table which is stored in a memory of the motor vehicle, adding the wear index values assigned to the detected driving events and driving conditions to calculate a total wear index value, and at predefined distance readings of the motor vehicle, comparing the total wear index value with an associated reference total wear index value defined by stored reference characteristic information.
