Detailed Figures and Location Information

Your Audi A4 purge valve keeps fuel vapors safely stored in a carbon filter while your car is off. Once you start your engine, the purge valve opens and allows these trapped vapors to enter your engine. This not only prevents harmful vapors leaking into the atmosphere, but also improves your fuel economy. Where is the purge valve located? The position of this solenoid varies from one vehicle to another, so view an Audi A4 and sedan 1999-05 repair guide to determine the location and your purge valve and EVAP canister.

Inspect your purge valve, canister, and the rest of the EVAP system to determine the location of the leak. This system creates a vacuum, so even the smallest leak can illuminate your Check Engine Light and require sealing. From your gas cap to the canister, find the essential replacement parts you need online or at your nearest AutoZone location to keep your Audi A4 running like a dream.
