Differential Lock Valve – VW T3 Syncro (OE 857711981)

Valve for controlling the differential lock on the Volkswagen T3 Syncro. This valve is part of the pneumatic actuation system and regulates the vacuum used to engage or disengage the differential lock.

When the differential lock switch on the dashboard is operated, this valve directs vacuum to the actuators on the front or rear differential, allowing the differential lock to engage or release as needed.

A faulty or leaking valve can cause the differential lock to fail to engage, disengage incorrectly, or remain permanently engaged.
