OE 165941017K — Headlight for Volkswagen

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.

A supersession happens when the maker revises a headlight and issues a new tail number. The revision normally changes a small physical detail rather than the fit. Where we know a supersession chain for 165941017K we list the current reference; ask our desk for written confirmation before a large order.

Incoming batches pass a dimensional check, a material look-up against the engine & fuel system specification, and a visual inspection for finish defects. Critical dimensions are measured per carton and the photographs are archived against the order number.

Three checks: the code printed on your old part must read 165941017K; 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.

Start from the code cast or printed on the part you are removing — that is the authoritative source. If it is illegible, use the Applications table on the closest engine & fuel system reference and narrow by build year. Send photos and we will cross-check the number for you.
