What is the function of an Audi mass air flow sensor?

I recently purchased an Audi A4 and I've been hearing about the mass air flow sensor. Can someone explain what it does and why it's important in the car's performance?

The function of an Audi mass air flow sensor is to measure and monitor the amount of air flowing into the engine. This information is then used by the car's computer to determine the correct air to fuel ratio for efficient combustion. It is a crucial component in maintaining the overall performance of the car.

The Audi mass air flow sensor is responsible for detecting any changes in the airflow in the engine. It then sends this data to the car's computer, which adjusts the fuel injection and ignition timing accordingly for optimal performance. Without a functioning mass air flow sensor, your car's engine may experience issues such as poor fuel economy and decreased power.
