After authenticating at least one functional component which is safety-relevant and/or emission-relevant to the driving mode of the motor vehicle with regard to whether the functional component is an original component of the motor vehicle or a functional component which has been replaced without authorization and/or has been manipulated without authorization, the operation of at least one other functional component of the motor vehicle is controlled in such a manner that the functionality or at least one functionality of the at least one other functional component is selectively restricted if the authentication which has been carried out reveals that the at least one functional component which is safety-relevant and/or emission-relevant to the driving mode of the motor vehicle has been replaced without authorization and/or has been manipulated without authorization.

Method for controlling the operation of at least one functional component of a motor vehicle and motor vehicle

In a method for operating a motor vehicle, encrypted data is exchanged between a sensor and a control device via a bus. An item of information required for decrypting the exchanged data is provided by a user of the motor vehicle by way of a portable device. The encrypted data includes measurement values of the sensor which relate to an operating state of a component of the motor vehicle.

The present invention relates to a method and a corresponding system for catalytic aftertreatment of the exhaust gas of an internal-combustion engine. Two spatially separate catalyst devices are provided in the exhaust gas system. The first of these catalyst devices is arranged in a position close to the engine, and the second catalyst device is arranged in a position away from the engine. An exothermal reaction is caused to take place during warm-up for heating the second catalyst device.
