What is the role of the diverter valve in an Audi 80?

I am learning about the engine components in an Audi 80 and I came across the diverter valve. What is its specific purpose and how does it work?

The diverter valve in an Audi 80 is responsible for redirecting excess boost pressure back into the intake system, preventing damage to the turbocharger.

This valve also helps improve the gas mileage of the car, as it helps regulate the amount of air and fuel being used by the engine.

To make sure your diverter valve is functioning properly, check for any leaks or cracks and replace if necessary. It's also important to regularly clean and maintain the valve to prevent build-up and damage.
