2720510177 BEMWQ Variable Timing Solenoid for Mercedes Benz W204 W211 M272

This is the BEMWQ Variable Timing Solenoid (Part Number: 2720510177 / A2720510177), also widely known as a Camshaft Adjusting Magnet or Oil Control Valve (OCV). It is a critical actuator for the Variable Valve Timing (VVT) system in Mercedes-Benz vehicles equipped with the M272 engine. This solenoid regulates the flow of engine oil to the camshaft adjuster, allowing the ECU to precisely advance or retard the valve timing. This dynamic adjustment optimizes engine performance, fuel efficiency, and emissions control across varying RPMs and loads.

• Precision Fitment:​ Specifically engineered for Mercedes-Benz chassis models including C-Class (W204) and E-Class (W211) with M272 engines, ensuring a direct OEM-standard fit without modification.

• High-Response Electromagnetic Coil:​ Manufactured with high-quality internal coils and durable housing materials designed to withstand harsh engine bay oil temperatures and pressure, ensuring fast and accurate response to ECU signals.

• OE Specifications:​ Built to match original equipment standards in terms of electrical specifications (typically 12V, 2-pin), flow rate, connector type, and thread specification, guaranteeing seamless integration with the existing VVT system.

• Restores Engine Performance & Smoothness:​ Replacing a faulty, sticky, or electrically failed solenoid eliminates symptoms such as rough idling, hesitation during acceleration, reduced power, and poor fuel economy, restoring the engine's original drivability.

• Clears Fault Codes & Warning Lights:​ Effectively resolves common VVT-related diagnostic trouble codes (such as P0016, P0017, or camshaft correlation errors) and turns off the Check Engine Light (CEL) caused by timing misalignment.

• Direct Plug-and-Play Installation:​ Matches the factory solenoid's exact dimensions and connector design, allowing for a straightforward, hassle-free replacement process for both professional mechanics and DIY enthusiasts (typically involving unplugging the electrical connector and removing one mounting bolt).
