Land Rover Part Number: STC4198 - Turbocharger Vacuum Control Valve
STC4198 is a turbocharger vacuum control valve fitted as an electro-mechanical solenoid to regulate vacuum for turbo boost control and, on applicable diesel engines, for exhaust gas recirculation (EGR) vacuum regulation. The valve modulates vacuum signals from the engine management system so the turbo actuator and the EGR valve operate as required; it connects to the engine vacuum hoses and the vehicle wiring harness. Faulty units commonly cause loss of boost control, limp-home modes or EGR-related fault codes, so correct replacement is important for engine response and emissions behaviour. Use the compatibility data below to confirm fitment against your V.I.N.

Frequently Asked Questions
STC4198 is an electro-mechanical solenoid that directs engine vacuum to vacuum-operated actuators for turbo boost control and, where fitted, for the EGR valve. It modulates vacuum signals from the engine management system and connects to vacuum hoses and the vehicle wiring harness; failure typically affects boost control and can trigger EGR or engine management fault codes.
