Q&A:

Q1: Will this resolve “Airmatic malfunction” or “vehicle rising slowly” messages?
A1: If caused by a weak or failed compressor, yes. Also inspect air springs/lines for leaks and verify the compressor relay and fuse are within specification.

Q2: Is coding required after installation?
A2: Many vehicles self-adjust after battery reset and a short drive, but a suspension level calibration with professional diagnostics is recommended.

Q3: What’s included with the pump?
A3: The compressor assembly with integrated dryer. Reuse the factory bracket, air lines, fittings, and relay unless damaged.

Q4: How can I extend compressor service life?
A4: Repair any air leaks promptly, replace aged air springs, ensure the dryer/desiccant is effective, and replace a sticking relay that can cause overrun.

Q5: How do I confirm it fits my S-Class?
A5: Match your VIN and the part number on the original compressor to the references above and confirm your car uses Airmatic (not ABC).
