Q&A:

Q1: My W221 sits low or makes knocking noises, will this help?
A1: Yes, if the problem is caused by a worn or leaking air strut. Replacing the faulty unit will restore proper ride height and damping. Also inspect the compressor and other struts for wear.

Q2: Should I replace both shocks on the same axle at once?
A2: This is recommended. Matched struts give balanced damping and even ride height from side to side.

Q3: Do I need a wheel alignment after installation?
A3: Yes. Any major suspension work should be followed by a professional alignment to protect tyres and keep handling correct.

Q4: Is coding or calibration required after fitting?
A4: The system usually operates once fitted and bled of air, but a suspension calibration or level relearn with diagnostic equipment is recommended for best ride quality and height accuracy.

Q5: How do I confirm that this fits my S-Class?
A5: Use your VIN in the Mercedes parts catalog or ask your dealer, then match the original part number and suspension option to the references listed above for W221 models with Airmatic.
