Abstract
A method for controlling or regulating a level control system for a motor vehicle including a compressed air source, at least one air spring, a switchable directional control valve associated with the air spring and a master line connecting the compressed air source to the switchable directional control valve. The switchable directional control valve blocking the master line in a normal state thereof and connecting the master line through for filling the air spring in a switching state thereof. The master line is filled with compressed air before filling the air spring until the air pressure in the master line is at least equally as high as a predetermined threshold value, and only thereafter is the switchable directional control valve transferred into the switching state for filling the air spring. A level control system for a motor vehicle is also provided.
