Forge Motorsport Dump Valve Kit for VAG 1.0 TSI/GTI FMDV18

This valve kit allows the fitment of a fast response blow off valve on the VAG 1.0 TSI/GTI engine, including the VW UP.

As the engine does not have a diverter valve fitted as standard, Forge Motorsport have developed a twin piston dump valve that not only gives you an incredibly loud sound when lifting off the throttle but it also increases the throttle response during gear changes by reducing turbo lag. It is designed to help the turbocharger maintain its rotational speed ready for when you accelerate, as well as prolonging the life of your turbo.

Due to the exposed position of the OEM boost pipe and the nature of an engines heat cycle, the plastic the OEM pipe is made from can deteriorate over time becoming brittle and susceptible to boost leaks. This kit totally replaces this plastic pipe from turbo to manifold with a silicon hose (available in a choice of colours), and everything else you need to install the valve is included in the kit together with full instructions.

• Anodised CNC machined billet couplers and components along with a tuneable CNC machined twin piston Forge Motorsport valve.
• Custom colours are available but will incur a 50% none refundable deposit and a lead time of 8-10 weeks.
• Unlike other valves on the market the Forge valve will not bring on any check engine lights. (EML) 
• The Forge silicone hoses in this kit have been designed to include an expensive inner liner of modified silicone known as Fluorosilicone. This ensures the colour of the silicon hose stays bright and vibrant and unlike our competitors will not deteriorate over time.
• Lifetime warranty.

We cannot guarantee that this product will fit with all aftermarket intakes. Please note if you have the extra spout on your inlet pipe as seen in the picture below then this part will now fit your vehicle

Please note that the 2021 Engine may have some differences due to the map sensor and turbo charger coupler difference, please study the pictures below, if your map sensor and screw type coupler look like this pictured below, FMDV9 and FMDV18 are not compatible. 

It is the customers responsibility to ensure fitment before purchasing, any returns of correctly supplied parts will be subject to a 25% re-stocking fee.

Do not use aggressive (acidic) car cleaning products, particularly traffic film remover solutions or shampoos to clean your intercooler, radiator, or oil cooler. The use of these products can damage Forge Motorsport cooling systems and invalidate your warranty. These are often found at car washes. A light, warm, soapy solution (free of harsh acidic cleaning compounds) should be used to clean you cooler and thoroughly rinsed away. We recommend that you should inspect your product on a regular basis for bent and/or crushed fins. Any bent fins should be carefully straightened to allow ambient air to pass through the core face. At the time of installing your Forge radiator, an approved coolant must be used and added to the coolant system. Be sure you never mix coolant and always use distilled water.

This warranty does not apply to any defect in the goods arising from fair wear and tear, wilful damage, accident, negligence by you or any third party, use otherwise than as recommended by the supplier, failure to follow the supplier’s instructions, or any alteration or repair carried out without the supplier’s approval.
