How to Enhance the Reliability of a Land Rover Discovery’s Air Suspension System?

The Land Rover Discovery, a vehicle in the luxury SUV category, is touted for its unrivaled prowess both on and off the road. A notable feature that makes the ride smooth and comfortable is the air suspension system. It plays a crucial role in maintaining the vehicle’s height and ensuring a premium ride regardless of the terrain. However, like any other mechanical part, the air suspension system can develop issues. This article will carry you through the necessary steps to enhance the reliability of your Land Rover Discovery’s air suspension system.

Understanding the Air Suspension System

Before diving into the ways to improve the system’s reliability, it’s essential to first comprehend what the air suspension system is and how it functions. Found in the Rover series, this system uses air bags filled with pressurized air in place of traditional coil springs. The system is designed to adjust the ride height based on the vehicle’s speed and the terrain, providing superior comfort and exceptional ground clearance when needed.

When the vehicle is at high speeds, the system lowers the ride height to improve stability and aerodynamics. On rough terrains, it raises the vehicle to increase clearance and prevent damage to the undercarriage. The air suspension system offers improved handling and more refined ride quality compared to traditional suspension systems.

The air suspension system is made up of various components, including air bags, air compressor, height sensors, and control module. They work together to adjust the ride height and hardness of the suspension. The air bags are usually located at the rear of the vehicle, replacing the coil springs in the suspension.

Identifying Common Problems with the Air Suspension

A well-maintained air suspension system can offer you years of trouble-free service. However, some common issues might appear over time due to wear and tear or lack of proper maintenance. Recognizing these problems early can help you address them promptly and avoid costly repairs.

One common problem with the air suspension system is air leaks. This can lead to the system failing to maintain the desired height, affecting the ride quality. Air leaks often occur in the air bags due to their location and exposure to road debris and harsh weather conditions.

Another issue is the failure of the air compressor. The air compressor is responsible for supplying the pressurized air to the bags. If it’s not working properly, the vehicle’s ride height might not adjust as needed, causing poor ride quality and handling issues.

Faulty height sensors can also cause problems. They send data to the control module about the vehicle’s height and the road conditions. If they fail, the system might not adjust the ride height appropriately, which can affect the vehicle’s performance and comfort.

Regular Maintenance for the Air Suspension System

Regular maintenance is crucial to keep your air suspension system running smoothly. It not only helps prevent issues but also extends the lifespan of the system. The maintenance process involves inspecting the various parts of the system, checking for leaks, and ensuring the system is functioning as it should.

Begin by checking the air bags for any visible signs of damage or wear. Also, check the compressor for any signs of overheating or excessive noise, which could indicate a problem. The height sensors should also be inspected and cleaned regularly to ensure they’re providing accurate readings.

In addition to these checks, the system should be serviced by professionals at regular intervals. They can identify any potential issues and rectify them before they cause more serious problems. Regular service can also keep the system calibrated, ensuring it responds properly under different driving conditions.

Upgrading the Air Suspension System

Upgrading the air suspension system with high-quality accessories and parts can enhance its reliability and performance. There are various upgrades available, such as high-performance air compressors, air bags, and control modules. These upgrades provide enhanced durability and improved performance, making the system more reliable and efficient.

For instance, you might want to consider upgrading the air bags. High-quality air bags offer improved durability and can withstand harsh conditions better than standard ones. As for the compressor, consider a high-performance model that can deliver pressurized air more efficiently.

In conclusion, maintaining the reliability of your Land Rover Discovery’s air suspension system involves understanding the system, identifying common problems, performing regular maintenance, and considering upgrades. With proper care and maintenance, your vehicle can continue to offer the exceptional ride quality and performance that the Land Rover Discovery series is known for.

Using the Right Parts Catalog for the Air Suspension System

To ensure the longevity and optimal performance of your Land Rover Discovery’s air suspension system, it’s critical to use the right parts. A reliable parts catalog like the Atlantic British can be a valuable resource for this. The catalog provides a wide range of high-quality parts for your Rover series, including the Rover Discovery and Rover Range.

The parts catalog offers specific details about each part, including its function, compatibility, and installation process. This makes it easier for you to select the right parts for your air suspension system. Whether it’s the air bags, the air compressor, height sensors, or the control module, ensure that the parts you choose fit your vehicle model and meet the recommended standards.

When using the parts catalog, pay particular attention to the air bags. These are a key component of the air suspension system and are often subject to wear and tear. The Atlantic British offers high-quality air bags that are designed to last and withstand harsh driving conditions.

The Roverlog News Blog and Shop Overland are other excellent resources for finding quality parts and accessories for your Rover Discovery. They offer a comprehensive selection of parts, including those for the air suspension system, and provide helpful tips and information on maintaining your vehicle.

Transitioning from Air Suspension to Coil Suspension

Despite the advantages of air suspension, some Land Rover owners may prefer the traditional coil suspension for its simplicity and lower maintenance costs. If you’re considering making the switch, it’s important to understand what it entails and the potential impact on your vehicle’s performance.

Coil suspension systems use metal springs to absorb the shock of uneven terrains. While this system offers a rugged and durable option, it may not provide the same level of ride comfort and adaptability as the air suspension system.

Transitioning from air to coil suspension involves replacing the air bags, air compressor, and other air suspension components with coil springs and shock absorbers. Though it may initially seem like a daunting task, kits are available to simplify the process. These kits come with clear instructions and all the necessary parts for the conversion, making it a relatively straightforward process.

However, keep in mind that making this change may alter the ride quality and handling characteristics of your Rover Discovery. It’s recommended to consult with a professional or a reliable Land Rover forum before making the decision.


The air suspension system of your Land Rover Discovery plays a pivotal role in maintaining a comfortable and smooth ride. Enhancing the reliability of this system involves understanding its components, identifying common issues, carrying out regular maintenance, choosing quality parts from a trusted parts catalog like the Atlantic British, and considering upgrades. While transitioning to a coil suspension system is an option, it is crucial to weigh the pros and cons before making such a decision. By following these measures, you can ensure that your vehicle continues to deliver the exceptional performance and ride quality that the Discovery series is renowned for. Whether navigating rough terrains or cruising at high speeds on the highway, a well-maintained suspension system ensures your Rover Discovery is always ready for the journey.
