Pierburg Diverter Valve

The Pierburg Diverter Valve, with an OEM part number of 06H145710C and MPN 7.02901.05.0, is a crucial component for maintaining optimal turbocharger performance in a wide range of Volkswagen and Audi vehicles. This updated 'C' version features a revised diaphragm-based design, intended to be more robust than previous revisions, such as the 06H145710J. Factory diverter valves are known to fail, sometimes as early as 20,000 miles, leading to symptoms like boost leaks under hard acceleration or strange noises after gear changes. Replacing a faulty valve with this genuine Pierburg part can restore lost boost and ensure proper turbo function. This diverter valve is manufactured in Germany and is a direct-fit replacement for many Audi and Volkswagen models equipped with 1.8T, 2.0T (including Gen 1, Gen 2, and Gen3 TSI engines), and 2.5T engines. Specific fitment includes models such as the Arteon, Atlas, Beetle, CC, Golf (V, VI, VII), Jetta (V, VI, VII), Passat B7, and Tiguan. However, it is important to note that specific engine codes may apply; for example, it fits the Golf V and Jetta V 2.0T models only if they are equipped with the CCTA or CBFA engine code. Always verify compatibility using the vehicle selector or by checking your existing part number before ordering, as some listings indicate the part is VIN specific.
