Hello! I own my 04 Disco w/83K original miles. Had it since — I drive it little obviously. I intend to keep it. Anytime it needs anything it gets new OEM. Lately, its dash started showing the three amigos erratically on and off. My mech scanned and read it pointing to the shuttle valve switch ($85): https://www.roverparts.com/brakes/calipers-cylinders-hydraulics-vacuum/SWO500030/
Contacts at dealer and two other reputable sources at supply parts concurred.
Another source #3 at Atlantic British suggested that in the last couple of years more reports and findings pointed to not just the shuttle valve switch but more than likely also the modulator guts that needed change ($730): https://www.roverparts.com/brakes/calipers-cylinders-hydraulics-vacuum/SWO500040/
I spoke with #3 and he stated, changing the shuttle valve switch alone might work. It may fail after a few months — if it does and the lights come on again then the modulator would have to be changed, which means changing the shuttle valve switch with it yet again for $730 + labor.
My contact at LR dealer, service foreman, that had the same vehicle, said the shuttle valve switch is all that he changed on his (same vehicle) and that was it.
Attached is a screenshot of the findings. How does one make an intelligent decision as to what to change at this point?
