Air suspension diagnostics is required when you hear a knocking sound or an unusual noise in case of a sudden turning or similar sound effects when driving on an uneven road or when reaching a certain speed. You also need to check the air suspension if the car spins when braking and when turning, even on dry roads, or if your car sways when driving or from the wind. In the course of diagnostics, the experts check the presence of air leaks, assessing the noise level in the system after the engine is turned off. Next, they inspect the air bags, glasses and pneumatic lines for defects; check the level of compressor performance, the condition of the moisture separator and the pneumatic system dryer. After that, the experts will check the degree of overheating of the compressor and the piston, as well as the condition of the filter after the ingress of water into the pneumatic system.
