1. A method for removing one or more of user-specific and drive-specific user data which are saved on a plurality of controllers in a motor vehicle, comprising:
detecting a digital vehicle key signal from a vehicle key configured to unlock the motor vehicle;
automatically detecting a particular trigger condition, from a plurality of different trigger conditions, based on the detected digital vehicle key signal;
automatically determining a particular trigger condition level, from a plurality of different trigger condition levels having different associated delete routines, and automatically identifying a particular delete routine associated with the particular trigger condition level, the particular delete routine specifying particular user data to be overwritten or deleted from one or more of the plurality of controllers;
in response to detecting the particular trigger condition and identifying the particular data deletion routine associated with the particular trigger condition level, transmitting a specified common delete command to the one or more controllers of the motor vehicle via a data bus of the motor vehicle; and
executing the particular delete routine to overwrite or delete the particular user data saved in the one or more controller.
