Abstract

The invention relates to a coupling actuator comprising a master cylinder, a hydraulic line and a slave cylinder, for actuating a coupling. The invention also relates to a method for detecting a leakage on a coupling actuator comprising the following steps: a parameter of the coupling actuator is determined, the parameter is compared to a predetermined threshold value, if the parameter exceeds the threshold value, a warning of a leakage is provided, and the warning is communicated.
