Range Rover Air Suspension Manual Override
The Range Rover air suspension system consists of several major components. Air bags sit in the four corners of the vehicle, and can be inflated or deflated to adjust the vehicle body's height from the wheel base. Height sensors also sit in each corner of the vehicle and detect its distance from the ground.
The air compressor and storage tank store and filter air, and the valve block routes air to different corners of the car. Lastly, the electronic control unit regulates the system's settings and allows the driver to adjust the vehicle's height.
Many of these parts are expensive to replace, and if any of these components fail, then the entire air suspension system can no longer function. A variety of other components of the air suspension system are susceptible to damage. For example, the air compressor can eventually wear out, resulting in slow pumping. When the pumping system becomes too slow, an error message will result. The valve block, which is the most expensive components of the system, can eventually start leaking or can fail to shut off air flow between the various springs. The electronic control unit can fail, causing the system to incorrectly regulate the air suspension system.
When a component of the system faults, it is usually obvious. The dashboard error light will read “EAS FAULT,” and the air springs may deflate.
Range Rover Sport Suspension Error
When this happens, the Range Rover should be taken in for a diagnostic test. Because air suspension components can be costly to replace, some Range Rover owners choose to replace the air suspension system with steel springs. This eliminates air suspension system problems, although this may not be a desirable option for Range Rover owners who take advantage of the vehicle's off-road abilities. Range Rover owners can also avoid air suspension problems with regular maintenance. Periodically draining the air tank, replacing the inlet air filter, and checking for crack, blocks, or leaks can prevent future problems.
SUSPENSION60-12DESCRIPTION AND OPERATIONThe electric motor drives a crank with an eccentric pin to which a connecting rod is attached. The connecting rod has a piston which fits in the bore of the compressor. Operation of the motor rotates the crank, moving the piston in the bore of the compressor. The compressor is attached with special bolts to the motor housing and sealed with an O- ring. The compressor has a temperature sensor located in its housing. The sensor measures the compressor temperature which is measured by the air suspension ECU.Attached to the compressor is the air dryer which contains a silicate box for removing moisture from the compressed air. Air supplied to inflate the air springs passes through the air dryer. When the air springs are deflated, the exhaust air also passes through the air dryer, removing the moisture from the unit.Attached to the end of the air dryer unit is a solenoid operated exhaust pilot valve.
