Q&A:

Q1: Will this fix a “vehicle rising slowly” or “leveling malfunction” warning?
A1: If the fault is due to a weak or failed compressor, yes. Always check for air leaks in springs/lines and verify the relay and fuse are within spec.

Q2: Is coding required after installation?
A2: Most vehicles will self-adjust after battery reset and short drive; however, a suspension calibration/level relearn with professional diagnostic equipment is recommended.

Q3: Does this include the relay, air lines, or mounting bracket?
A3: The compressor is supplied as the pump assembly. Reuse the factory bracket, lines, fittings, and relay unless they are damaged.

Q4: How can I extend compressor life?
A4: Replace any leaking air springs or lines, ensure the dryer/desiccant is fresh, and verify the system relay isn’t stuck, which can cause overrun.

Q5: How do I confirm fitment?
A5: Match your VIN and the part number on the original compressor to the references listed above for the W164 ML-Class.
