8D0862257C AUDI A4 B5 Zentralverriegelungspumpe – Originalteil, gebraucht und geprüft

Beschreibung

Genuine used Audi central locking vacuum pump with OEM number 8D0862257C, primarily fitted to selected Audi A4 B5 vehicles equipped with the corresponding pneumatic central locking system. This original factory unit combines the vacuum pump and electronic control functions required for operation of the vehicle’s locking system.

The pump creates and regulates the vacuum or pressure used by the central locking actuators and works together with the vehicle’s pneumatic lines, electrical wiring and locking mechanisms. Depending on production year and equipment specification, Audi used several different pump versions that can appear very similar externally but differ internally in electronics, coding and supported vehicle functions.

This is an original used Audi/VDO component and may show normal cosmetic signs from previous installation, removal, handling or storage. Minor scratches, marks or surface wear are typical for genuine second-hand automotive parts.

Before ordering, compare OEM number 8D0862257C carefully with the reference printed on your existing unit. The final letter C is important and should not be ignored when choosing a replacement. We also recommend checking the connector arrangement, pneumatic ports, pump casing and vehicle equipment configuration.

Correct diagnosis of the central locking system is recommended before replacing the pump, as similar symptoms may also be caused by leaking vacuum hoses, faulty lock actuators, damaged wiring or other electrical problems.
