Range Rovers are known for their off-road capabilities, and the Range Rover air suspension system makes it possible for the vehicle to navigate a variety of different terrains. However, these air suspension systems tend to wear out over time, leading to potentially expensive repairs. The Range Rover’s air suspension system consists of a number of different components, all of which must be in working order.
Background, range rover sport suspension failure
In 1993, the conventional coil spring suspension system was replaced by air suspension on some Range Rover models. The air suspension system improved the Range Rover’s ability to negotiate off-road terrain by allowing the vehicle’s height from the ground to be adjusted. In 1995 air suspension became standard on all Range Rover models. Electronic Air Suspension System (EAS) software inflates or deflates the air springs based on car speed and terrain.
Major components: calibrate range rover sport air suspension
The Range Rover’s air suspension system consists of several major components. Airbags are positioned at all four corners of the vehicle and can be inflated or deflated to adjust the vehicle’s body height from the wheelbase. Height sensors are also placed at 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 directs air to different corners of the car. Finally, the electronic control unit regulates the settings of the system and allows the driver to adjust the height of the vehicle. Many of these parts are expensive to replace, and if any of these components fail, the entire air suspension system can no longer function.
Problems with air bags: range rover sport air suspension problems
Damaged airbags are a common problem on Range Rovers. Air bags can develop leaks at the top and bottom when they are old, or they can spontaneously explode when punctured. Slow air bag leaks can overload the air compressor pump. Bags often start leaking at 100,000 miles or after six years in most climates.
Sensor problems: how to unlock range rover air suspension system
Faulty air suspension sensors are another common problem. Range Rover’s air suspension sensors can become damaged due to inclement weather or when pushed beyond their limits. Any sensor failure can make it impossible to level the vehicle. Also, a disconnected sensor can cause the suspension to get stuck at a height.
