Mercedes-Benz CLS, E-Class Rear Air Suspension Spring Set A2123204025, A2123203925

Air suspension springs age identically. If the rear left bag has cracked and failed, the rubber on the rear right side has endured the exact same amount of flex wear and road hazard exposure. Replacing only one side almost always results in the opposite side developing a leak within a few weeks, leading to double the labor costs.

Yes, absolutely. When an air spring develops a constant leak, your central AIRMATIC air compressor is forced to run continuously to maintain vehicle ride height. Because these factory compressors are designed only for brief, intermittent cycles, running continuously will quickly overheat the motor, causing it to burn out completely. Fixing a leaking bag immediately protects your expensive air compressor from collateral failure.

No software programming or SCN coding is necessary. However, a professional OBD2 diagnostic scanner is highly recommended during installation to safely deflate the remaining air from the system before disassembly and to command a controlled initial inflate cycle to prevent the new bags from twisting or pinching as they expand.
