Land Rover Variable Timing Solenoid - Genuine Land Rover LR045390

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

About Genuine Land Rover

The same parts Land Rover used to build your vehicle are sold as replacement parts under the “Genuine Land Rover” brand. These are manufactured under Land Rover’s direction, guaranteeing top quality. As you’d expect, they also carry a premium price and are sold exclusively through the Land Rover dealership network.

Genuine Land Rover parts trace their origins back to the earliest days of the brand in 1948, when Rover engineers built the first Series I using robust, serviceable components designed for durability in harsh environments. Over the decades, Land Rover established partnerships with leading European suppliers to ensure consistent quality and performance. This tradition continues today, with Genuine Land Rover parts representing the official replacement components engineered to the same specifications as those used on the production line.

What many owners don’t realize is that Land Rover doesn’t manufacture most of these parts themselves. Instead, they design the components, contract trusted suppliers to produce them, and then verify the quality. Many of these suppliers have partnered with Land Rover for decades. In the industry, they’re known as OEMs (Original Equipment Manufacturers)—brands you probably recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. It’s not unusual to open a Genuine Land Rover box and find one of these brands inside—just re-badged with a Land Rover logo.

On our site, look for OE tags on product pages to quickly spot parts that come straight from the original manufacturers. Choosing these can save you a significant amount compared to buying them in Genuine packaging. For more details on how to identify OE and OEM parts, check out our OE Academy.
