Metzger 06J 109 257 Q VVT Oil Control Valve Variable Valve Timing Solenoid

The Metzger 06J 109 257 Q is a Variable Valve Timing (VVT) oil control valve solenoid — also commonly referred to as a camshaft adjuster valve or cam timing control solenoid — designed as a direct OE-replacement for Volkswagen and Audi VAG-platform engines. This hydraulically actuated control valve regulates oil pressure flow to the camshaft phaser, enabling the engine management system to continuously adjust camshaft timing for optimal performance, fuel economy, and emissions.

Key Features:

• Functions as the VVT oil control valve (OCV) and camshaft adjuster solenoid
• Hydraulic drive type — uses engine oil pressure to actuate cam phaser
• M21 threaded housing with 1.0 mm thread pitch
• Installs directly on the engine camshaft
• Direct OE replacement — no modifications required
• OEM Reference: 06J 109 257 Q
• Supersedes / Cross-Reference: 06J109257M, 06J109257G

A failed or clogged VVT oil control valve can trigger a check engine light and may cause symptoms such as rough idle, engine hesitation, pinging under acceleration, or poor fuel economy. Replacing a faulty unit with a quality aftermarket solenoid like this Metzger unit restores proper variable cam timing function and helps return engine performance to factory specification.
