An air suspension system for a motor vehicle and a method of operating thereof includes an air suspension device for adjusting a ride-height position of the motor vehicle by the feeding and removal of compressed air into a plurality of air springs. The system also includes a dryer supplied via a compressed-air supply unit which has a compressor driven by an electric motor. A control unit for performing a ride-height control function has instruction for: raising the ride-height position to a first ride-height position; subsequently lowering the ride-height position to a second ride-height position; checking a first condition whether a determined air quantity ratio is less than a first predetermined air quantity limit value; checking a second condition whether a saturation level of the dryer is greater than a saturation limit value, and activating the ride-height control function when either the first or the second condition is satisfied.
