Description

The Bosch Fuel Pressure Regulator, part number 0-280-160-575, is engineered to precisely control fuel pressure within your vehicle's fuel lines. It functions by bypassing excess fuel back to the return system once a set pressure of 4 Bar (approximately 58 psi) is achieved, ensuring optimal fuel delivery. This component is specifically noted for its common use in performance applications, often called for in certain software programs for 1.8T engines. Constructed from durable stainless steel, this regulator is built to withstand demanding conditions. It replaces OE part numbers such as 078133534C and is a direct replacement part. A failing fuel pressure regulator can manifest in various drivability issues, including incorrect fuel mixture (running too rich or too lean), difficulty building fuel pressure, or inconsistent pressure levels, all of which can impact engine performance and longevity. This regulator is compatible with a wide array of Audi and Volkswagen models, including various A4, A6, A8, S4, S6, TT, Golf, Jetta, Passat, and Corrado configurations spanning several engine types such as 1.8T, 2.7T, V6 variants, and more. However, it is crucial to utilize the vehicle selector tool to confirm exact fitment for your specific year, make, model, and submodel.
