What It Helps Address

• Hesitation during acceleration
• Stalling or rough running
• Poor fuel economy
• Poor engine performance
• Intermittent airflow sensor faults caused by worn solder joints or damaged internal components

Installation Notes and Tips

Before replacing the sensor, inspect the air filter, intake tract, connectors, and wiring for dirt, debris, looseness, cracks, or damage. Moisture intrusion, shorted wiring, over-voltage, air intake obstructions, and oil or fuel fumes can contribute to sensor failure. If the engine reacts when the unit is lightly tapped, the sensor may be faulty and should be replaced.

For best results, verify the part number and confirm the BMW application before installation. The bolt-on design and included housing support direct replacement on the listed vehicles.

Quality Assurance

Each Cardone remanufactured Mass Air Flow Sensor is tested with automated computer equipment and validated on vehicle to confirm form, fit, durability, and performance requirements. The remanufacturing process is designed to deliver reliable electrical connections and consistent operation across demanding temperature conditions.
