GFB VW & Audi

DV+ diverter valves, including versions with an integrated solenoid, replace the factory bypass valve using the original electronics. VTA (vent-to-atmosphere) diverter valves are offered for owners who want an audible release, while DVX Sound Adjustable valves allow the noise level to be varied. The range also includes boost taps for Golf and 1.2/1.4 TSI applications, Hybrid, Respons, Mach 2 and Deceptor Pro II blow-off valves for older 25mm Bosch-style fitments, lightweight crank pulleys and small service items such as springs, plungers and blanking plates.

VAG models are best identified by chassis or platform code rather than model year alone. Look for codes such as Golf Mk4 through Mk8 (including 1K/5K), Audi A3/S3 (8L/8P/8V), A1 (8X), A4 (B5/B6/B7/B9), TT/TTS (8N/8J/8S), Q2 (GA), Q3 (8U/F3), S4/RS4 and S5/RS5 (B9), A6/S6 and A7/S7 (C8), Skoda Octavia (1Z/Mk2/Mk3/5E) and Fabia (5J). Engine family matters too, with many valves listed for EA113 or EA888 units and separate parts for 1.2/1.4 TSI and twin-charged engines. Check the exact codes in the product title against your build plate before ordering.

Most diverter valves are a direct swap for the factory unit and reuse the standard wiring plug where the product description says so, while VTA and boost tap products may require hose routing or plumbing changes. Typical tools include metric sockets and Torx bits, hose clamps and, for pulley work, the correct crank pulley tooling and belt. Installation by a professional workshop is recommended, particularly for pulley, wastegate and boost control products, and any change to boost behaviour should be checked by a qualified tuner.

Will a DV+ keep my factory solenoid function? DV+ valves are designed to work with the original electronic control, and some versions are supplied with an integrated solenoid where the platform requires it.

Will a vent-to-atmosphere valve suit my car? VTA valves release air outside the intake tract, which suits some setups better than others; check the product listing for the platforms GFB lists it against.

How do I confirm fitment? Match the chassis code and engine family shown in the product title to your vehicle, and contact us if your variant is not listed.
