Mercedes-Benz W203 W211 W219 Steering Shaft And Column Adjustment Motor 404.475 - Used Original Parts

Diagnosis and Common Symptoms

As a Senior Technician at M.S. Motor, I frequently diagnose steering geometry and column faults across premium German platforms. On the Mercedes-Benz W203, W211, and W219 architectures, the steering column adjustment motor (404.475) is a highly active component that suffers from thermal fatigue and internal wear over time. The primary failure manifests as a complete loss of telescopic or tilt actuation. Drivers usually first notice that the Easy Entry/Exit convenience feature fails to move the wheel out of the way when the ignition is turned off.

When scanning the Steering Column Module (MRM) or the driver-side SAM, you will commonly retrieve fault codes such as 9345 or 9346, which indicate the adjustment mechanism is blocked, or the motor control circuit is experiencing an open or short circuit. These failures are typically caused by internal carbon brush degradation or mechanical binding in the column drive cables, which forces the motor to draw excessive amperage until the module cuts power to prevent an electrical fire.

Introduction

When repairing the intricate steering column dynamics of your W203, W211, or W219 chassis, relying on Genuine parts is absolute necessary to maintain factory tolerances. This Genuine used steering column adjustment motor has been rigorously bench-tested to ensure flawless operation and proper voltage draw under load. By choosing a verified pre-owned component, you restore exact factory precision to your steering ergonomics without the steep dealership markup. Every unit is physically inspected for drive gear integrity and complete electrical continuity before it reaches your bay.
