Spotting Symptoms of a Mini Cooper S Diverter Valve Failure

Mini Cooper S Diverter Valve Failure Symptoms are a set of problems that can arise from the malfunction of a diverter valve. The diverter valve is an important part of the engine, as it acts as a switch to direct air flow between the intake manifold and the turbocharger. When this valve becomes faulty, or begins to wear out, it can cause a variety of symptoms that can range from decreased performance to complete engine failure. Common symptoms include poor fuel economy, sluggish acceleration, rough idle, hesitation or “flat spots” in acceleration and power loss. Additionally, you may hear whistling or hissing noises coming from the engine bay as air is escaping through the faulty valve. If left unchecked, this fault can lead to engine failure due to overworking of the turbocharger and other parts of the exhaust system. If you suspect your Mini Cooper has a diverter valve problem then it is recommended you take your vehicle to a qualified mechanic for further inspection and repair.
