Problem overview

Some Mercedes-Benz CL550 owners report experiencing a lack of power to the starter following an Airmatic pump failure, which may be linked to several underlying issues. Commonly, these owners find that a dead battery, alternator problems, or a failed starter could contribute to the power loss. Additionally, Airmatic pump motor problems can lead to battery draining issues, further affecting the starter's power supply. In cases where the Airmatic pump failure impacts the starter, it is essential for owners to check the relay and fuse for the air suspension system, as low readings may indicate power supply issues. Furthermore, some owners may need to inspect and potentially replace components such as the rear airbags, Airmatic relay, compressor, and pressure sensor, while also checking for leaks in the valve block. Addressing these concerns promptly is crucial to ensure proper power supply to the vehicle's systems.
