06J109257L – Genuine VVT Oil Control Valve (20mm) for VW Golf Mk6 Mk7, Audi A4 B8 | YDU

Description

Function: Controls oil flow to the variable valve timing (VVT) camshaft adjuster on the intake or exhaust camshaft, enabling optimised engine performance, fuel efficiency, and emissions across the RPM range. Valve diameter: 20mm. Common failure symptoms include illuminated Check Engine light, fault codes P0010, P0011, P0012, P0020, P0021, P0022 (camshaft position actuator circuit or performance faults), rough idle, reduced power, increased fuel consumption, and rattling or knocking noises on cold start. Replacement advice: Always replace the oil control valve filter/strainer screen at the same time and flush the engine with fresh oil if sludge contamination is suspected — a blocked screen is a leading cause of valve failure. Torque specification for retaining bolt: approximately 8–10 Nm (verify against current workshop manual for specific engine code). Fitment is primarily associated with EA888 Gen 2 and Gen 3 four-cylinder turbocharged petrol engines; verify your engine code (e.g. CDNB, CCZB, CJSA, CJSB, CNCD, CXCA, CXEB, CZPB) before ordering. Also replaces: 06H109257N, 06J109257B, 06J109257C, 06J109257F.
