Workshop Installation Advisory

Crucial Workshop Note: On the W166 and X166 platforms, compressor motor failure is almost always the consequence of minor air leaks in the rear rubber spring bladders (air springs) or the solenoid valve distribution block. Before installing the replacement unit, perform a soapy water leak test across all pneumatic components. Always replace the system compressor relay simultaneously to protect against stuck electrical contacts and motor burnout.
