GFB DV+ Diverter ValveGFBs DV+ solution couldnt be simpler keep what works and replace what doesnt. GFB expands the DV+ range with a direct fit solution for the weak factory diverter valve used on many European vehicles. The solenoid coil itself from the factory fitted valve is great (the ECU opens it faster than any pneumatic valve so why replace it?), but the weak point however is the valve mechanism itself. So GFBs DV+ solves this problem by replacing just the valve
