The BMW EGR valve is a component in two vehicle systems, providing essential functions in both to help keep your vehicle operating at its most efficient. The BMW EGR valve is located on the intake manifold in most vehicles. In older model vehicles it uses a vacuum connection to operate, while in newer vehicles it is usually electronic. The BMW EGR valve is designed to help in the reduction of harmful vehicle emissions, and to assist with the prevention of detonation in the engine combustion process. Detonation is caused by an inefficient burn of fuel in the engine, resulting in an explosion rather than the clean and efficient burning of fuel that yields the best engine performance. Detonation can be very damaging to vital engine parts, often leading to expensive repairs. If the BMW EGR valve has malfunctioned, it can affect the performance of the vehicle, causing such symptoms as a loss of engine power, excessive exhaust emissions, engine ping or knock, and poor fuel mileage. The BMW EGR valve not only contributes to the efficient performance of the vehicle, but also is crucial to meeting the tough vehicle emission standards that are enforced in most states. The BMW EGR valve is specifically calibrated for each engine model, making it important to be sure that you choose the right one for your specific vehicle model and year of production to ensure the best performance and efficiency.
