GFB T9357 DV+ Diverter Valve Upgrade – BMW N20/N26 2.0 Turbo (228i, 328i, 428i, 528i, X1, X3, X4, Z4) 2011–2016

What it is

A replacement for the plastic diaphragm diverter valve on BMW's N20/N26 turbo four. The factory valve's diaphragm tears and leaks boost, especially on tuned cars; the DV+ keeps the BMW solenoid coil and replaces only the valve body and piston with billet aluminum and brass. Boost is held, throttle response sharpens, and the ECU sees exactly what it expects because the air still recirculates.

Fits

N20 and N26 engines in the F-series 2/3/4/5-series, E89 Z4, E84 X1, F25 X3 and F26 X4, roughly 2011–2016 (N26 is the SULEV version of the N20 in some US states). Check the engine code on your car; the B48 that replaced the N20 in 2016–2017 uses a different GFB part.

What's in the box

Valve housing with piston and spring, O-rings, bolts, instructions. The factory solenoid coil is reused.

Installation

Access is the only hard part: the diverter sits behind the turbo and most owners loosen the turbo heat shield or manifold to reach it. 1–2 hours with the right extensions. No coding.

Why GFB

Go Fast Bits (Australia) designed the DV+ specifically around OE electronic diverters, which is why it has become the default fix for failing BMW, VW and Ford diverter valves rather than a loud atmospheric BOV.
