OE 1665400217 — Wheel Speed Sensor for Mercedes-Benz

Three checks: the code printed on your old part must read 1665400217; the number must fall inside the build-year range in the Applications table; and the connector, thread or bolt pattern must match the reference photo. Codes cast into the housing are the most reliable source.

Report it with the order number and packing-list line plus photographs. Because every carton is photographed before loading, we can trace the batch immediately and settle the claim against the inspection record instead of arguing from memory.

Aftermarket wheel speed sensor comes from tooling houses that hold the original drawings or licensed equivalents. KingMay sources from vetted factories and inspects each batch; the manufacturer name is available on request where your market requires origin documentation.

Noise normally traces to worn internal surfaces, a loose mount, a dry bearing or contact with a neighbouring part. Isolate it by reproducing the sound at a fixed speed, then compare against the reference photo for 1665400217 to confirm the right replacement.
