Forge Motorsport - Vacuum Diverter Valve upgrade for VAG 2.0T FSI / Gen 1 TSI
This valve is for VAG vehicles equipped with the 2.0T FSI, TSI or TFSi engines that have electronically controlled bypass valves.
This valve 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.
The Forge Motorsport alternative is a fully engineered solution offering both significantly improved reliability as well as valve related boost response. This 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.
