Detailed Description

Use this Hella mass air flow sensor to restore accurate intake air measurement on supported Audi and Volkswagen models. The sensor is specified for vehicles with OE No. 03L906461A, making it a focused replacement choice for drivers searching for a 2015-2016 Audi A3 mass air flow sensor, a 2014-2015 Volkswagen Golf MAF sensor, or a 2012-2015 Volkswagen Passat airflow sensor. The Pierburg distributed by Hella line provides an OE-referenced option for maintaining consistent engine control input.

What It Helps Address

• Incorrect airflow readings from a failing MAF sensor
• Rough idle or unstable engine operation

Installation Notes

Verify the OE number on the original sensor before ordering. Confirm connector style, housing shape, and engine application against the vehicle’s existing part, especially on Audi A4 and Volkswagen Golf platform vehicles. After installation, clear diagnostic trouble codes and perform a road test to confirm normal airflow readings.
