Mercedes S-Class W221 Air Suspension Compressor Failure
The Airmatic air suspension compressor on W221 S-Class fails progressively, causing the car to sit low on one or more corners, particularly after overnight standing. The compressor motor burns out from continuous operation due to leaking air bags or lines. Replacement compressor costs £250-600; always locate and fix the leak source first or the new unit will fail again.
