This product fits VW and Audi models, OEM number 0258006257, also compatible with 0258006258, 0258006255, 0258006305, etc. When installing, ensure the engine is cold to avoid burns, use a dedicated socket to avoid thread damage; also check sensor wiring harness and connectors and ensure the seal ring is properly installed to prevent leaks.
