An exhaust flap for an exhaust system of a motor vehicle, which has an internal combustion engine and an electronic processing device for a closed-loop control of the internal combustion engine, has a valve element, an actuator for moving the valve element, and a dedicated electronic processing device. The dedicated electronic processing device is configured to receive a first signal which is provided by the electronic processing device of the motor vehicle and which characterizes a first position of the valve element, generate a second signal which characterizes a second position of the valve element as a function of the received first signal, and transmit the second signal to the actuator. The actuator moves the valve element into the second position based on the received second signal.
