Mercedes-Benz W212 Electric Power Steering (EPS) Rack Assembly - Used Original Parts

Diagnosis and Common Symptoms

From the workshop floor, the W212 EPS rack is a known failure point. The primary indicator is the "Power Steering Malfunction" warning on the instrument cluster, often accompanied by a complete and sudden loss of steering assist, resulting in extremely heavy steering. Symptoms can be intermittent at first, failing after the vehicle warms up, but will inevitably lead to a permanent fault.

Physical symptoms include a binding or "notchy" sensation when turning the wheel, or a persistent humming noise from the electric motor. Diagnostic scans will typically reveal fault codes related to the power steering control module, motor position sensor, or an internal electronic fault within the assembly itself.
