2730940948 BEMWQ Air Mass Meter for Mercedes Benz W204 V212 W211 X204 W636 W272

The BEMWQ Air Mass Meter (Part No.: 2730940948) is a high-precision Mass Air Flow (MAF) sensor designed for Mercedes-Benz vehicles. It is compatible with a broad range of models equipped with M272 and M273 engines, including the W204 (C-Class), V212/W212 (E-Class), W211 (E-Class), X204 (GLK-Class), W639 (Vito/Viano), and W221 (S-Class). Positioned in the intake tract immediately after the air filter, this sensor accurately measures the mass and density of incoming air, providing critical real-time data to the ECU for calculating the optimal air-fuel mixture .

• Exact OEM Specification:​ Manufactured to match the original equipment standard 2730940948, ensuring precise fitment, correct 5-pin connector alignment, and seamless integration with the vehicle’s air intake housing without modification .

• High-Precision Measurement:​ Utilizes calibrated sensing elements to deliver accurate and responsive airflow readings, enabling the engine control unit to maintain the ideal stoichiometric ratio for efficient combustion across all RPM ranges .

• Durable Construction:​ Built with robust housing materials and quality internal electronics designed to withstand engine bay heat, moisture, and vibrations, ensuring long-term reliability .

• Plug-and-Play Design:​ Engineered as a direct electrical and mechanical replacement, allowing for straightforward installation using existing mounting points and connectors for immediate operation .

• Restored Engine Performance:​ Eliminates common issues caused by a failing MAF sensor—such as sluggish acceleration, hesitation, rough idling, and erratic RPM fluctuations—by restoring accurate airflow data to the engine management system .

• Improved Fuel Efficiency & Emissions:​ Helps optimize fuel delivery based on real-time air intake, correcting rich or lean running conditions, which can lead to better gas mileage and reduced harmful exhaust emissions .

• Check Engine Light Resolution:​ Directly addresses common MAF-related diagnostic trouble codes (e.g., P0100-P0104 series) and sensor circuit faults, turning off the dashboard warning light and preventing the vehicle from entering reduced-power "Limp Mode" .

• Cost-Effective Maintenance Solution:​ Provides a dependable and economical alternative to OEM parts for resolving airflow measurement issues, ensuring smooth drivability and protecting the engine from improper fueling wear .
