A method for operating an electromechanical steering system for a motor vehicle with variable chassis height, with a steering rack, which is driven by a servo motor through a recirculating ball screw drive, with a control unit, which receives input signals and generates output signals for driving the servo motor, the output signals being representative of an assist torque to be provided by the steering system, may be characterized in that, in operation, the control unit may receive or generate a chassis height signal that may indicate a current chassis height of the vehicle, and may limit the assist torque, on the basis of the chassis height signal, to an upper limit, wherein the upper limit may be decreased with an increase of the difference between the current chassis height and a mean chassis height.
