Some BMW 750Li owners report experiencing issues with the Level Control System after servicing the air struts, indicated by the activation of the leveling system light. These problems may arise from a malfunctioning air suspension, which can prevent the vehicle from raising or self-leveling properly. Symptoms of a failing suspension system include warning messages about Level Control Malfunction, hissing sounds from air springs, and imbalances in car height, alongside compressor engagement issues and prolonged operation. Additionally, replacing air struts may lead to uneven air distribution or excessive raising of the rear of the vehicle. Leaking air springs can further disrupt suspension balance, triggering warning messages. Owners are advised to check for leaks, ensure proper air distribution, and verify that the air suspension system is functioning correctly to address these concerns.
