Information
Variable Valve Timing Solenoid (VVT)
The Variable Valve Timing (VVT) solenoid (also called a camshaft adjustment valve or oil control solenoid) controls oil flow to the camshaft system, adjusting valve timing in response to engine speed, load, and driving conditions. By continuously optimising camshaft position, it enhances engine efficiency, performance, and emissions. Designed to exacting standards, it delivers smoother idle, improved torque and fuel economy, and reliable long-term operation with a precise, direct fit.
Sold each, 2 required per vehicle.
Fits:
Porsche 996 C2 3.6L 09/01 - 2005 (for engine code M96.03)
Porsche 996 C4 3.6L 09/01 - 2005 (for engine code M96.03)
Porsche 996 C4S 3.6L 09/01 - 2005 (for engine code M96.03)
Porsche 997.1 C2 / C4 3.6L 2005 (up to engine number 695 08637)
Porsche 997.1 C2S / C4S 3.8L 2005 (up to engine number 685 11779)
Porsche 997.1 Turbo 2007 - 2009
Porsche 997.2 GT2 RS 2011 - 2013
Diagram ref no 40
Core Functions:
• Regulates the flow of pressurized oil to the camshaft phaser or actuator.
• Adjusts valve timing dynamically to match engine speed, load, and throttle input.
• Optimizes power delivery, fuel consumption, and emission control.
• Ensures smooth idle and responsive acceleration.
• Helps reduce exhaust emissions and improve combustion stability.
When working correctly, it keeps the engine running at peak precision, balancing performance and efficiency seamlessly.
Over time, the variable valve timing solenoid can degrade due to contamination, wear, or electrical faults. Common causes include:
• Oil contamination or sludge buildup blocking the internal oil control passages.
• Low oil quality or irregular oil changes, which reduce hydraulic efficiency.
• Electrical faults within the solenoid connector or wiring harness.
• Mechanical sticking of the plunger or valve spool, preventing proper timing adjustment.
• Prolonged engine overheating causing internal seal failure.
Failure Symptoms:
Check Engine Light (CEL) or camshaft timing fault codes. Rough idle or engine stalling. Reduced power, sluggish acceleration, or poor fuel economy. Rattling noise from the timing area. Higher emissions or failed MOT/inspection.
Replacing a worn or faulty VVT solenoid restores your engine’s optimal performance and efficiency.
Key Benefits of Replacement:
• Restores precise valve timing for consistent torque and smooth power delivery.
• Improves fuel economy by optimizing combustion under all loads.
• Eliminates rough idle and hesitation during acceleration.
• Prevents costly engine damage caused by improper timing or lubrication.
• Reduces emissions and ensures compliance with modern environmental standards.
• Ensures long-term reliability and consistency under demanding driving conditions.
A fresh VVT solenoid returns your vehicle to the refined performance level it was designed to deliver, ensuring precision control and reliability mile after mile.
Advantages at a Glance:
• Precision oil flow control for accurate camshaft timing
• Improved engine performance and throttle response
• Smoother idle and reduced vibration
• Enhanced fuel efficiency and reduced emissions
• Durable construction with long lifespan
• Plug-and-play compatibility for quick installation
• Developed to deliver original-quality performance at excellent value
