Overview

The Forge Motorsport FMDV1 is a dump valve designed for the 2015-on 1.2 and 1.4 TSI engines. This valve replaces the factory setup to provide the traditional dump valve noise during gear changes and when releasing the throttle. The kit includes a silicone hose, available in multiple colors, to replace the turbo-to-manifold pipe, along with all necessary installation hardware and instructions.
Show original supplier description
The Forge Motorsport FMDV1 is a dump valve engineered for the 2015-onward 1.2 and 1.4 TSI engines, commonly found in a range of VAG vehicles including Skoda Fabia, Skoda Octavia, VW Golf, VW Polo, Audi A1, Audi A3, Seat Ibiza, and Seat Leon. This aftermarket valve replaces the factory-diverter valve system to introduce the distinct dump valve sound during gear shifts and when the accelerator is released. Unlike other aftermarket solutions, the FMDV1 is designed to not trigger check engine lights (EML), ensuring seamless integration with the vehicle's electronics and maintaining original driving behavior. This hose is constructed with a Flurosilicone inner liner, making it resistant to modern coolants (including O.A.T.) and oil mist, exceeding the performance and durability of stock hoses. However, compatibility with all aftermarket intake systems cannot be guaranteed. A blanking plug is included for vehicles that do not have a secondary breather. Important fitment notes: This FMDV1 kit is specifically for models that do not have a standard turbo-mounted diverter valve. Vehicles equipped with a factory turbo-mounted diverter valve will require a different kit (part number FMDVA1TSI and FMDVATSI). Additionally, this valve setup will not fit the VW Golf GTE. Forge Motorsport provides a lifetime warranty on this product, ensuring long-term reliability and performance.
