Valve Block solenoid fault Diagnosis
Common fault with Range Rover air suspension valve solenoids is they stop distributing the air pressure to the individual air struts/air bags controlled by the air suspension system ecu or you may get a corner of the vehicle sinking down overnight ,their are usually 1 main valve block solenoid located under the driver passenger floor next to the air receiver air tank and the remaining 2 cross link valve solenoids located near the front and back rear suspension ! their are diagrams in the gallery pictures illustrating the positioning of these solenoid units on L322 Range Rover models 2002 – 2004/5 . A common reason why these solenoids fail is that the orings become deformed/flattened in their seated positions due to continued use over many years of service which allows vital air pressure to escape pass the individual solenoids also the lack of servicing of the air suspension compressor air dryer chamber filtration allows the filtration media to break down like a sugar like substance thus passing through into the valve block solenoids themselves causing damage to orings and the functionality of the electrical parts of the valve solenoids themselves. These individual valve block solenoids have to stay sealed all the time until they are requested to distribute air ,they also allow the vehicle to lower when instructed by opening valve solenoids together with the air suspension compressor exhaust valve to allow the air to exit the system thus lowering the vehicle ! any leaks in this circuit can cause a suspension system failure resulting in dashboard messages being illuminated ! Please checkout the gallery pictures illustrating the valve blocks themselves and the orings/seals within them for reference only.
