Diverter Valve

The Bosch diverter valve (also known as a bypass valve or turbo recirculation valve) is engineered as a direct replacement for the original component in various VW and Audi models equipped with 1.8T and 2.7T engines. Part number 06A145710N, this genuine VW Audi part is manufactured under the direction of VAG, ensuring excellent quality and performance consistent with factory specifications. This diverter valve plays a crucial role in managing turbocharger boost pressure. It recirculates excess air back into the intake system when the throttle closes, preventing compressor surge and protecting the turbocharger from damage. Replacing a faulty or worn diverter valve is essential for maintaining optimal engine performance, throttle response, and turbocharger longevity. The part is made in Germany and is considered a genuine VAG part, often manufactured by original equipment manufacturers (OEMs) like Bosch, which VAG entrusts with producing components for their vehicles. It is compatible with a wide range of Volkswagen Passat, Beetle, and Audi TT models from the late 1990s through the mid-2000s, specifically those with the 1.8L L4 or 2.7T engines. Comprehensive fitment details are available to confirm compatibility with your specific vehicle configuration.
