The invention relates to a method for monitoring a braking torque modification of a retarder, in particular of a motor vehicle, said braking torque modification being controlled by an actuating pressure control circuit comprising a pressure sensor that is connected in said circuit. The method comprises the following steps: the actuating pressure of the retarder is dynamically detected by means of the pressure sensor that is mounted in the actuating pressure control circuit; the temporal progression of the detected actuating pressure is compared with at least one predetermined target progression; a warning is issued and/or a future activation of the retarder by a user, in particular the driver of the vehicle, is prevented, based on the actual- target comparison and if predetermined criteria have been fulfilled.
