Product Details

The 7.22184.68.0 mass air flow sensor measures incoming air for the engine management system so the vehicle can calculate fuel delivery and airflow-related adjustments. For Audi R8 and Audi A8 Quattro models listed above, this sensor is matched to OE No. 420133471 and should be selected by exact application rather than by appearance alone. If you are replacing a failing Audi R8 mass air flow sensor or sourcing a 7.22184.68.0 replacement for an Audi A8 Quattro, verify the OE number before ordering.

Common Issues This Part May Address

• Incorrect airflow readings stored by the engine control system
• Rough idle caused by inaccurate air measurement
• Driveability concerns related to air-fuel calculation errors
• Check engine light conditions tied to the mass air flow circuit
• Poor throttle response from a worn or contaminated sensor

Installation Notes and Tips

Confirm the OE number 420133471 and compare the existing sensor before installation. Inspect the intake tract, connectors, and sealing surfaces for contamination or damage, and clear any diagnostic trouble codes after replacement. Because fitment is specific, use the vehicle year and model listing for Audi R8 and Audi A8 Quattro applications rather than relying on a universal match.

Quality Assurance

Hella and Pierburg distributed by Hella identify this as a cataloged replacement sensor for the listed OE application. Part number 7.22184.68.0 is provided for precise identification and fitment verification.
