Detailed Description

Built under Bosch’s Mass Air Flow Sensor (New) product line, this sensor is engineered to match original equipment function and calibration requirements. The Bosch 0280218390 measures incoming air so the engine control system can calculate fuel delivery accurately, which is important for drivability, idle quality, and emissions performance. It is a direct replacement for vehicles such as the 2006-2010 Volkswagen Beetle, 2005-2008 Volkswagen Jetta, 2010 Volkswagen Jetta, 2004-2006 Volkswagen Phaeton, and 2003-2006 Porsche Cayenne. This part also cross-references 07C906461 and 95560612300 for the same application.

Common Issues This Part May Resolve

• Rough idle caused by inaccurate airflow readings
• Hesitation or poor throttle response during acceleration
• Check engine light related to mass air flow sensor performance
• Incorrect fuel trim from faulty air metering data
• Emissions test failure tied to sensor signal problems

Installation Notes and Tips

Before installation, confirm connector style, flange mounting, and inlet/outlet diameter match the original sensor on the vehicle. Inspect the intake tract for leaks, contamination, or damaged wiring, since those conditions can affect sensor readings. For best results, install the Bosch 0280218390 on the listed Volkswagen and Porsche applications using the original mounting points and verify all connections are secure after replacement.
