Installation Notes and Tips

Verify the BMW part number and vehicle application before installation. This compressor includes the relay, wiring harness, dryer, and mounting hardware, and it uses a three-hole mounting pattern. Confirm that the vehicle is equipped with the correct WABCO OES air suspension compressor setup, especially on 7-Series models with xDrive or hybrid variants.

For best results, inspect the air lines, electrical connectors, and related suspension components before replacing the compressor. If the original compressor failed from contamination or excessive run time, check the system for leaks or damaged components that could shorten service life.
