Mercedes Benz W222 W213 W205 Comfort Seat Control Module A2228706866 – Original Used Part

Diagnosis and Common Symptoms

The A2228706866 comfort module is the brain behind the multi-contour seat functions in modern Mercedes-Benz chassis. Failure typically occurs due to under-seat moisture accumulation, electrical shorts in the seat harness, or internal processor degradation. Common symptoms include a complete loss of seat adjustment, non-functional massage features, or bolsters that refuse to inflate or deflate. From a diagnostic standpoint, you will often see CAN-bus communication errors or fault codes such as B1E41 indicating an internal hardware malfunction. If your seat controls are intermittently responsive or have "frozen" entirely, the control module is the primary suspect.
