Go Fast Bits GFB DV+ (DV Plus) Piston Turbo Diverter/Bypass Valve - BMW 5 Series F10 520i 184hp 2011-2018 N20 | Recirculation Boost Control/Compressor Bypass | Blow-Off Valve Alternative | Direct-Fit Upgrade for Faster Spool & Response

DV+ Bypass Valve Upgrade for BMW 5 Series F10 520i 184hp 2011 to 2018

Want factory-smooth driveability with stronger boost control and none of the whooshy theatrics? This GFB DV+ upgrade replaces the fragile OE boost bypass unit on the 2.0 turbo 520i with a robust, precision piston assembly that keeps the car quiet, responsive and consistent.

What you will feel

• Crisper accelerator feel and quicker turbo recovery between shifts
• Stronger boost retention to help reduce loss of pressure under load
• A reliable solution to common leak issues found on many stock valves
• Durable metal internals engineered for longevity
• Uses the car’s original control strategy, so no warning lights or mapping required
• Recirculates air back into the intake for OEM-level refinement and no extra noise

We have fitted this upgrade ourselves and customer feedback has been excellent. It tightens the way the car picks up and holds pressure, making everyday driving feel more immediate and consistent without adding unnecessary sound.

Compatibility

BMW 5 Series F10 Saloon 520i 184hp, model years 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018.

Why this upgrade works

The DV+ swaps out the factory diaphragm-style unit on the compressor housing for a piston-based design that resists leaking and heat soak. By retaining the original electronic control and recirculating path, it integrates seamlessly while delivering firmer sealing, quicker response and dependable boost management.
