What It Helps Address

Installation Notes and Tips

Verify the vehicle’s chassis and model year before ordering, since fitment is specific to the listed Mercedes-Benz GL-Class and ML-Class applications. Inspect the air hose, electrical connector, relay circuit, and related suspension components during replacement to help prevent repeat compressor failure. Because this compressor plugs directly into the factory air hose and electrical connector, it is intended for direct replacement on the confirmed applications.
