Problem overview

Some Mercedes-Benz S500 owners report experiencing issues with air bag leaks that cause the shocks to lose pressure, resulting in the vehicle sagging, particularly after being parked for an extended period. These leaks are a common problem associated with the AirMATIC suspension system and can be identified by visible wear or damage in the rubber components, often accompanied by a hissing sound. Repairing these leaks involves addressing the source, which may include tiny holes in the AirMATIC struts or tears in the rubber air springs. Additionally, some owners have raised concerns about the safety implications of air suspension problems, including potential relay faults, compressor malfunctions, and valve blockages, which can lead to costly repairs. Regular maintenance and inspection of the air suspension system are crucial for preventing leaks and ensuring optimal performance, highlighting the importance of prompt diagnosis and repair to maintain a smooth and safe driving experience.
