Compatibility

Confirmed fitment: Mercedes S-Class W220 (RWD, without 4Matic), model years 1998–2006. Confirm the fit by matching your old part number to the OE cross-reference below before ordering.

When to replace it

Common signs this part has failed:

• The car sits low or leans to one side after being parked
• A harsh or crashing ride as damping stops adapting
• A 'raise vehicle' or suspension warning on the dash
• The suspension compressor runs longer and more often
• A hissing air leak from the failing strut

On the W220 — the oldest AIRMATIC generation — the lower protective dust boot tends to crack after high mileage, letting grit wear through the rubber air-spring bladder, which is a common cause of leaks on this model.
