Audi VW Camshaft Adjuster Solenoid - Genuine VW Audi 03H906455

Product Information

An Engine Variable Valve Timing (VVT) Solenoid is an essential component of an engine's variable valve timing system. It controls the flow of oil to the VVT system, which adjusts the timing of the opening and closing of the engine's intake and exhaust valves. This adjustment allows for optimal engine performance, improved fuel efficiency, and reduced emissions by enabling the engine to operate more efficiently across different RPM ranges.

• Check Engine Light: A malfunctioning VVT solenoid often triggers the Check Engine light. Diagnostic trouble codes (DTCs) related to the VVT system may be stored in the vehicle's onboard diagnostics, indicating an issue with the solenoid or related components
• Poor Engine Performance: If the VVT solenoid is failing, it can cause the engine to experience poor acceleration, hesitation, or overall reduced power. This is often due to incorrect valve timing affecting the engine's ability to breathe properly
• Rough Idling: A faulty VVT solenoid can result in unstable or rough idling, as the engine may struggle to maintain a consistent RPM due to improper valve timing adjustments

You may not realize this, but the parts that make up your VAG are not necessarily manufactured by VAG. No cause for concern, as VAG designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for VAG for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine VAG parts box and find an OEM branded part inside, simply with the addition of a VAG logo.
