A method for leakage monitoring of a compressed air system of a motor vehicle is disclosed. The compressed-air system has a compressed air supply system, a compressor, and a plurality of compressed-air consumer circuits. The method includes: a) successive detection of a supply pressure via a pressure sensor in a main supply line or in a supply line of at least one compressed air consumer circuit at a predefined time interval; b) successive calculation of pressure gradients of the supply pressure from at least two consecutively detected pressure values; c) comparison of the determined pressure gradients with a predefined gradient limit value; and d) output of a warning signal when the pressure gradient within a predefined monitoring time period which comprises a plurality of delivery pauses of the compressor has not exceeded the gradient limit value.
