Thread: Range Rover Sport Suspension Issue

The heavier front could be lower than the rear due to pressures having equalised if the system exhaust (compressor exhaust or exhaust pilot valve) is blocked, rather than a blockage on the rear valve block.

Should be able to disconnect the gallery to compressor hose then and when "lowering" it'll just vent the gallery to ambient. That'll tell you if it's the exhaust valve or something else (not that I can think of anything else it could be). If you can drop the car then plugging it all back in should allow it to raise to normal height. You could then pull the fuse and wait for the service kit.
