Bosch 0280217515 Mass Air Flow Sensor

Bosch Mass Air Flow Sensor for Mercedes-Benz

The Bosch Mass Air Flow Sensor, part number 0280217515, measures incoming air so the engine control system can calculate fuel delivery accurately. This new Bosch sensor is a direct-fit emission control replacement for select Mercedes-Benz models, including C-Class, E-Class, CLK-Class, ML-Class, SLK-Class, and S-Class applications.

Bosch’s original-equipment background matters here: the sensor is built to OE-level specifications, and even a small deviation from the factory air-flow signal can trigger a check engine light. If you are servicing a Mercedes-Benz C240, C320, or E320 and need a precise air metering solution, 0280217515 is the part to verify.

Key Features

• Bosch Mass Air Flow Sensor, new replacement unit
• Part number 0280217515 for OE-style fitment verification
• Black plastic housing
• Measures intake air for accurate engine management
• Emission control sensor for select Mercedes-Benz vehicles
• Cross-reference: this part cross-references 1120940048 for the same application

Detailed Description

This Bosch Mass Air Flow Sensor is used to monitor the volume of air entering the engine so the vehicle’s control module can maintain proper air-fuel balance. It is a practical replacement for Mercedes-Benz models that rely on a precise MAF signal to support drivability, fuel control, and emissions performance. The Bosch 0280217515 is commonly selected for Mercedes-Benz C240, C320, E320, CLK320, ML320, ML350, SLK320, SLK32 AMG, C32 AMG, C280, and S350 service needs.

Because the sensor signal is critical, a worn or inaccurate unit can contribute to fault codes and drivability complaints. Using the correct Bosch 0280217515 replacement helps restore the airflow reading the engine management system expects.

What It Helps Address

• Check engine light related to mass air flow sensor performance
• Rough idle caused by incorrect air measurement
• Hesitation or poor throttle response
• Fuel trim issues from inaccurate airflow data
• Emissions-related faults on Mercedes-Benz air metering systems
