This valve is for VAG vehicles equipped with the 1.4T, 1.8T & 2.0T FSI or TFSi engines, including the latest models fitted with the IHI turbo, (or 1.4T using additional fitting kit FMBGFK3) that have the electronically controlled bypass valves. It is recommended for any vehicle where the boost pressure has been increased by an ECU software upgrade and for unmodified vehicles fitted with the earlier version of the OEM valve that operate in warmer climates, as a solution to the many failures of the diaphragm that have occurred.
Our alternative is a fully engineered solution offering both significantly improved reliability. Our valve and installation kit replaces the original unit with a pressure/vacuum operated piston valve that still also retains the desirable OEM ECU control over valve actuation. This product has been thoroughly designed and tested with the expressed intent of offering improved valve response and maintaining ECU control while resulting in absolutely NO fault codes, NO check engine lights, and no adverse effects of any kind. All of the necessary components and detailed instructions are included and everything is designed to make installation as simple as possible.
This kit is supplied with an additional uprated spring (coded Yellow) that may be required if the vehicle has had a significant boost increase.
Please note: If this valve is to be installed to the 1.4 Turbo engine, it will be necessary to additionally purchase our boost sensor adaptor FMBGFK3 – please see below in Related Products. This will NOT fit the 2013 onwards CMBA and CXSB engines where the turbos are mounted at the rear of the engine bay.
