 The Audi EGR valve is a small component that plays a role in two separate vehicle systems to help maintain the efficient operation of your engine. The Audi EGR valve is mounted on the intake manifold in most vehicles and functions mechanically in older vehicles using a vacuum connection, while in late model vehicles it is often electronic. Its purpose is to help in the reduction of harmful vehicle emissions, and to assist in the prevention of engine knock, or detonation in the engine combustion chambers. Detonation is the explosion of fuel in the combustion chamber rather than the clean and efficient burning of the fuel that is supposed to occur, and is capable of causing a great deal of expensive damage to vital engine parts. A malfunction in the Audi EGR valve can have a detrimental impact on vehicle performance, including such symptoms as a loss of engine power, poor fuel efficiency, excessive exhaust emissions and engine ping or knocking.
 The proper function of the Audi EGR valve is not only important to vehicle performance and efficiency, it is also necessary to pass the stringent vehicle emissions inspection requirements that are in place in most areas today. The Audi EGR valve is specifically calibrated for each engine model, making it important to choose carefully when shopping for your replacement, ensuring the Audi EGR valve you choose is suited to the needs of your particular vehicle model and production year.
