2720510177 BEMWQ Variable Timing Solenoid for Mercedes Benz W204 W211 M272

Product Introduction

This is the BEMWQ Variable Timing Solenoid (Part Number: 2720510177 / A2720510177), also widely recognized as a Camshaft Adjuster Magnet. 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 engine control unit (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 .

Product Features

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

• High-Response Coil & Durable Housing:​ Manufactured with high-quality internal coils and robust 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 resistance, flow rate, connector type, and thread specification, guaranteeing seamless integration with the existing VVT system .

Product Selling Points

• 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) .
