Abstract
A method for the diagnosis of at least one vehicle component of a motor vehicle involves a) generating a diagnostic script for a diagnostic device of a motor vehicle in a diagnostic script provision unit formed separately from the diagnostic device, b) transferring the diagnostic script by means of a transfer device to the diagnostic device of the motor vehicle, c) authenticating an implementation authorization for the diagnostic script, and d) implementing the diagnostic script in the diagnostic device. Step d) is only implemented in the case of a successful authentication according to step b).
