2720181382 BEMWQ Breather Hose for Mercedes Benz W204 V212 W211 X204 W636 M272

This is the BEMWQ Breather Hose (Part Number: 2720181382 / A2720181382), a vital component of the engine's Positive Crankcase Ventilation (PCV) system. It is designed for Mercedes-Benz vehicles equipped with the M272 engine, responsible for channeling crankcase blow-by gases and oil vapors back into the intake manifold for re-combustion. This process regulates internal engine pressure, reduces harmful emissions, and prevents oil leaks .

• Precision Fitment:​ Specifically engineered for Mercedes-Benz chassis models including C-Class (W204), E-Class (W211/V212), GLK-Class (X204), and Citan (W636) with M272 engines, ensuring a direct OEM-standard fit without modification .

• Durable & Oil-Resistant Construction:​ Manufactured from high-quality, reinforced rubber or specialized polymers designed to withstand harsh engine bay temperatures, constant exposure to oil vapors, and thermal cycling without becoming brittle or cracking .

• OE Specifications:​ Built to match original equipment standards in terms of inner diameter, length, bend configuration, and connector interface for seamless integration into the existing ventilation system .

• Prevents Oil Leaks & Pressure Buildup:​ Replacing a cracked, collapsed, or hardened hose helps relieve excessive crankcase pressure, preventing oil seals (such as the valve cover gasket) from blowing out and stopping oil leaks from the engine .

• Restores Engine Performance & Efficiency:​ Ensures proper crankcase breathing and vacuum control, which helps eliminate rough idling, reduce abnormal oil consumption, and prevent check engine lights caused by lean fuel mixture codes (e.g., P0171, P0174) .

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