Bosch Mass Air Flow Sensor for Mercedes-Benz

This Bosch Mass Air Flow Sensor is a direct-fit emission control sensor for select Mercedes-Benz models. Built with a black plastic housing, it is intended to restore accurate airflow measurement for engines that rely on precise air metering. Part number 0280218190 is used across a wide range of Mercedes-Benz applications, including C-Class, E-Class, ML-Class, GL-Class, and SLK models.

Key Features

• Bosch Mass Air Flow Sensor (New) for emission control applications
• Black plastic housing for OE-style fit and placement
• Single-sensor replacement for airflow measurement issues
• Direct application coverage for multiple Mercedes-Benz platforms
• Cross-references Bosch 0280218190 for the same application

Product Details

Bosch is an original equipment manufacturer, and this Mass Air Flow Sensor is built to support accurate engine air measurement on Mercedes-Benz vehicles. When airflow readings drift outside OE specification, the engine control module can trigger a check engine light and affect drivability. The Bosch 0280218190 helps maintain the airflow signal the engine management system expects, making it a practical replacement for vehicles such as the Mercedes-Benz C300, E350, ML350, and GL450. This part number 0280218190 is also referenced for several other Mercedes-Benz sedans, coupes, and SUVs in the listed fitment range.

What It Helps Address

• Check engine light related to mass air flow sensor performance
• Rough idle caused by inaccurate airflow readings
• Hesitation or poor throttle response during acceleration
• Fuel trim issues from incorrect air metering data
• Driveability problems on Mercedes-Benz C250, E550, and SLK350 applications

Installation Notes and Tips

Verify the connector style and vehicle application before installation, especially on SLK280 and SLK350 models that list both 4-pin and 5-pin configurations. Inspect the intake tract, air filter housing, and wiring connector for contamination or damage before replacing the sensor. After installation, clear diagnostic trouble codes and confirm that live airflow data is reading normally.

Quality Assurance

Bosch supplies original equipment components, and this sensor is manufactured to OE-level specification control for the listed Mercedes-Benz applications. Bosch notes that even a small deviation from original equipment specification can illuminate the check engine light, which is why accurate sensor output matters for proper engine management.
