OE 054905377A — Knock Sensor for Audi

Aftermarket knock 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.

Build-year coverage is listed row by row in the Applications table above. Where several generations share one number, the newer rows usually carry a revised suffix — compare the last four characters before buying, since a suffix change often means a different connector or bracket.

Standard minimum order is 10 pieces per part number. Mixed orders that combine 054905377A with other electrical & sensors references are welcome — that is how most clients fill an LCL or FCL container without over-stocking a single line.

Treat it as a wear item: inspect every 20,000-30,000 km and replace at the first sign of leakage, noise or performance loss. Real service life swings widely with climate, road surface and duty cycle, so mileage on its own is a weak indicator.

Three checks: the code printed on your old part must read 054905377A; 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.
