2720160134 BEMWQ Auto Ventilation Valve for Mercedes Benz W204 W211 X204 M272

This is the BEMWQ Auto Ventilation Valve (Part Number: 2720160134 / A2720160134), a core component of the engine's Crankcase Ventilation (PCV) system. It is designed for Mercedes-Benz vehicles equipped with the M272 engine, responsible for regulating crankcase pressure and directing blow-by gases and oil vapors back into the intake manifold for re-combustion, thereby reducing emissions and maintaining engine seal integrity.

• Precision Fitment:​ Specifically engineered for Mercedes-Benz chassis models including C-Class (W204), E-Class (W211), and GLK-Class (X204) with M272 engines, ensuring a direct, OE-standard fit without modification.

• Durable & Heat-Resistant Construction:​ Manufactured from high-quality, reinforced materials (such as high-grade plastic or polymer composites) designed to withstand harsh engine bay temperatures, oil exposure, and constant thermal cycling.

• OE Specifications:​ Built to match original equipment standards in terms of port sizing, diaphragm response, and flow control characteristics to ensure seamless integration and accurate pressure regulation.

• Prevents Oil Leaks & Pressure Buildup:​ Replacing a stuck, clogged, or failed valve helps relieve excessive crankcase pressure, preventing oil seals (like the valve cover gasket) from blowing out and stopping oil leaks.

• Restores Engine Performance:​ Ensures proper crankcase breathing and vacuum control, which helps eliminate rough idling, reduce abnormal oil consumption, and prevent carbon buildup in the intake manifold.

• Simple & Accurate Replacement:​ Matches the original mounting points and connector design exactly, allowing for a straightforward, hassle-free installation for both professional mechanics and DIY enthusiasts.
