The disclosure relates to a method for operating an adjustment drive of a motor-adjustable steering column for a motor vehicle, said steering column comprising an actuating unit with a rotatably mounted steering spindle, to which a steering wheel is attached, wherein the actuating unit is adjustable by at least one adjustment drive for setting a longitudinal position and/or height position of the steering wheel, wherein in the method: a) a setpoint value of an adjustment speed of the actuating unit is predefined; b) on the basis of the setpoint value, the at least one adjustment drive is driven with a voltage signal by way of at least one controller; c) an actual value of the adjustment speed of the actuating unit is detected after a predetermined time period and is compared with the setpoint value; and d) the setpoint value is reduced depending on the result of the comparison between setpoint value and actual value until the voltage signal for driving the adjustment drive lies below the maximum value of a supply voltage, in particular an onboard electrical system voltage of the motor vehicle.
