Located on the underside of each fuel rail, this valve is a safety device that releases fuel pressure when it exceeds a specified limit. Originally from the RS4 and R8, this Genuine VW/Audi fuel pressure regulating valve has a higher opening pressure (140 bar vs. 130 bar stock), making it a popular upgrade for 2.0T FSI owners running bigger turbo applications that need increased fueling headroom. A faulty valve can cause fuel rail pressure issues or fuel line leaks. Priced each.
