Remedy ABS Shuttle Valve Fault codes: the "tres amigos." Kit replaces the shuttle valve switches with the genuine WABCO part, plus the shuttle valve plunger seals, and new type retaining clips.
Our kit addresses brake fluid leaks into the switches ... the cause, not just the symptom. In our workshop we offer an unprecedented two-year warranty, and just fitting the cheaper Rover shuttle valve switch (SVS) kit everyone sells is not adequate. Hence, our solution: tried and tested.
Much less common, there is another tres-amigos cause to test for, while installing this kit: The instruction information provided with this kit explains how to do this. There is a circuit board, within the modulator between the shuttle valve switches themselves, and the main harness connector to the modulator. If intermittent through the modulator board, our kit will not repair that aspect. The poor connection is generally a cracked solder-joint on the board in the solenoid block, and it must be located and repaired. Alternatively the whole block can be replaced (Land Rover SWO500040, per TSB LTB00060), as so many are doing these days, with their blinders on, ignoring the obvious brake fluid leaks. Find a very good explanation here, of how to repair the old part, noting that the solder joints at the other end of the SVS proboscus also fail ... and can also be repaired. Again, our kit will not repair this circuit board: it only addresses the normal common problem causing the three amber warning lights.
But shuttle valve seals usually begin to leak at around 70k miles anyway. No magic -- face reality. We suggest changing them at the 60k Service. When removed for service, always test the modulator board for continuity too, and repair as necessary. This FW66 kit is for codes 1,6; 11,4; 11,1. If changing only the seals, and the switches are still good, you will not need this whole kit, click here for seal and clip kit alone.
Do as we do at Falconworks: Do it once. Do it right. Kit fits all Land Rover Discovery Series II (we are told it also fits Hummer with WABCO modulator). Includes genuine SVS pack, valve seals, valve seal retainers, and instructions.
