GFB BMW

DV+ Diverter Valves - piston-style upgrades that replace the internals or the complete assembly of the factory diverter valve, retaining the OE electronic control and quiet recirculating operation.

Integrated Solenoid Versions - complete valve units supplied with the solenoid built in for the relevant BMW applications.

Replacement Parts - GFB also lists DV+ plunger, piston and spring service items in its universal range if you need to service an existing valve.

BMW applications are identified by both chassis code and engine code. Common chassis codes in this range include F20 (1 Series), F22 (2 Series), F30 (3 Series), F32 (4 Series), E70 (X5M) and E71 (X6M). Engine codes listed include N13, N20 and N55.

Check your build plate or VIN for the chassis code, and confirm the engine code, as a single chassis may have been offered with more than one turbo engine. Where a product title lists several makes, the same valve is used across those platforms.

Diverter valve replacement typically involves accessing the valve on the turbocharger or intake plumbing, disconnecting the electrical plug, and transferring or replacing the assembly. Basic hand tools and a torque wrench are usually required, and some models need intake components removed for access.

Installation by a qualified professional workshop is recommended. Follow the instructions supplied with the product and check for boost leaks after fitting.

Will a DV+ make a blow-off noise? No. The DV+ is a recirculating valve and retains factory-quiet operation.

Does the factory solenoid stay in place? On most applications yes; some part numbers are supplied with an integrated solenoid instead. Check the product title.

Do I need a tune? These valves are designed as direct replacements and do not require a tune, though they suit tuned cars running higher boost.
