How to check air suspension on the Range Rover?
Land Rover Vogue / Land Rover Range Rover air suspensions in any case need to be poured with soapy water at the bend at the very bottom of the suspension where the rubber rolls onto the piston and see if bubbles appear. If possible, you should also check for leaks using a soap solution through pneumatic lines, which are connected to the suspension. Of course, full diagnostics and testing of the air suspension can be done at the service station.
At the service station, there is an opportunity to exclude the entire pneumatic system by disconnecting the pneumoline from the suspension which being diagnosed, connect to an external system, pump it up and leave, for example, overnight. Before this, of course, the height is measured. If, in the morning, car has «fell down», then definitely there’s problem in the suspension. If the position of the air suspension remains unchanged, then the problem is somewhere in the system.
