GFB T9380 DV+ – Optimized Diverter Valve for New-Generation VW & Audi Models

The GFB T9380 is a fully integrated diverter valve designed specifically for late-model Volkswagen and Audi vehicles. Unlike earlier models, recent OEM diverter valves cannot be modified or retrofitted with traditional DV+ components, which is why GFB engineered the T9380 as a complete, compact replacement.

Thanks to its low-profile, solenoid-integrated design, the T9380 installs easily without clearance issues—even in tight engine bays—and delivers the standout DV+ benefits:

• Sharper throttle response
• Faster boost recovery after gearshifts or throttle modulation
• Improved boost holding and reduced leakage
• Exceptional reliability, backed by GFB’s Lifetime Warranty

Why Upgrade? – OEM vs. GFB DV+ T9380

Even though the latest OEM diverter valves are more reliable than previous versions, they still suffer from limitations:

• Plastic construction leads to unreliable boost sealing
• Binary open/close operation causes power delivery disruptions during throttle adjustments
• Remote mounting on plastic pipes results in large leaks—up to 28L/min at 1 Bar (tested on a VW Mk8 Golf R)

How the T9380 Solves These Issues:

• Machined integral piston seat ensures a reliable seal, even on uneven plastic surfaces
• “Pilot actuation” system allows for progressive piston movement, smoothing throttle transitions
• Durable metal components and Viton face seals offer superior long-term performance

The result is a smoother, faster, and more reliable boost control solution that enhances both drivability and performance. Precision-built by GFB and protected under their Lifetime Warranty, the T9380 DV+ is the ultimate diverter valve upgrade for your late-model VW or Audi.
