Installation Instructions for GFB DV+ TMS valve (part # T9351)

Locate factory diverter valve solenoid. It will
either be mounted directly on the turbo
compressor cover, or can be mounted
remotely on cars like the Golf R

Unclip the wiring connector from the top of the
solenoid coil – note there is a small locking tab
that needs to be pulled in the same direction (as
indicated by the arrow opposite) as you pull the
connector to release it

Unscrew the 3 mounting screws and remove the
factory valve from the car
Now separate the factory valve mechanism from the solenoid coil, and install the GFB valve mechanism onto the
factory solenoid as follows:

Pull on the plastic “basket”
(revision D) or the diaphragm
shroud (revision G), the whole
assembly will pop off leaving the
bare solenoid coil. Keep the
yellow o-ring

Install the GFB parts onto the solenoid as shown below, using a little engine oil on the outside of the
piston. Make sure to use the GFB supplied spring inside the solenoid coil – the only factory parts you re-
use are the solenoid coil and the yellow o-ring:

Fit the valve/solenoid assembly to the car in the factory location using the supplied longer bolts, and re-
connect the wiring loom
