What is the EVAP Purge Valve?

The EVAP purge valve in your 2000 Audi A6 is a small, electronically-controlled valve that regulates the flow of fuel vapors from the fuel tank to the engine. It is typically located near the engine or the fuel tank, and it is connected to the EVAP canister through a series of hoses.
