Common Problems This Part Can Address

• Check engine light related to airflow sensor performance
• Rough idle caused by inaccurate air measurement
• Poor throttle response from a failing MAF sensor
• Fuel mixture issues tied to incorrect intake airflow data
• Driveability concerns on a Land Rover Discovery with a worn sensor

Installation Notes and Tips

Verify the part number 0280217532 against the original sensor before installation. Inspect the intake tube, electrical connector, and surrounding air ducting for contamination or damage that could affect sensor readings. After installation, clear diagnostic trouble codes and confirm that the engine runs smoothly under idle and light acceleration.

Quality Assurance

Bosch is an original equipment manufacturer, and this sensor is built to meet the application’s airflow measurement requirements for select Land Rover Discovery models. Because Bosch notes that even a small deviation from OE specification can trigger a check engine light, accurate part matching is important for proper operation.
