Complete Guide to Land Rover Air Suspension Problems
Introduction to Air Suspension of Land Rover
Land Rover vehicles are renowned for their off-road capability, luxurious interiors, latest technology and smooth ride. One of the brilliant features that contribute to their exceptional ride quality and versatility is the Electronic Air Suspension (EAS) system.
In this article, we’ll explore the ins and outs of Land Rover air suspension, including signs of failure, common issues, and maintenance tips.
Whether you’re a seasoned Land Rover owner or new to the brand, understanding your vehicle’s air suspension can help you keep it running smoothly for years to come.
Understanding the Land Rover Air Suspension system
The Land Rover air suspension system uses air springs (also called air bags or air shocks) instead of traditional coil sprins. These air springs are filled with compressed air by an air suspension compressor, which adjusts the ride height based on driving conditions.
The system also relies on ride height sensors to monitor and maintain the correct height of the vehicle. The air suspension system is controlled by the Electronic Air Suspension (EAS) module, which ensures the vehicle stays level and provides a comfortable ride.
However, when something goes wrong, you may see a suspension fault warning light on your dashboard, indicating a problem that needs attention.
Benefits of Land Rover Air Suspension
● Adjustable air suspension improves ride comfort.
● Enhances off-road capabilities by increasing ground clearance.
● Lowers the vehicle for fuel efficiency on highways.
● Provides a smoother ride by absorbing road imperfections.
Despite these benefits, the system can develop faults over time.
The most common Land Rover air suspension issues
Signs and symptoms
If your Land Rover’s air suspension system is experiencing issues, it will likely exhibit certain warning signs. These include:
● Uneven Ride Height: If one side of the vehicle sits lower than the other, the air suspension may not be distributing pressure evenly.
● Noticeable Sagging: The vehicle may appear lower than usual, especially when parked for long periods.
● Bumpy Ride: Air suspension is designed to absorb shocks efficiently. A rough or bumpy ride could indicate a malfunction.
● Warning Lights on Dashboard: The suspension warning light may illuminate, signaling a problem with the system.
● Noisy Air Compressor: An unusually loud air compressor might be struggling to maintain proper air pressure in the suspension.
● Longer Compressor Run Times: If the air compressor takes longer than usual to fill the air bags, there may be a leak or a failing component.
The Air Compressor and Storage Tank Problems in Land Rover
The air compressor and storage tank are essential parts of the air suspension system. Some key problems associated with these components include:
● Overheating Compressor: If the air suspension system has leaks or blockages, the compressor may overwork, leading to premature failure.
● Moisture Buildup in the Storage Tank: If moisture accumulates, it can cause corrosion or freezing issues in colder temperatures.
● Blocked Air Lines: Dirt and debris can clog air lines, leading to inefficient airflow and improper suspension function.
● Compressor Relay Failure: A faulty relay can cause the compressor to run continuously or fail to start, leading to suspension issues.
Effect of Air Suspension Issues on Vehicle Performance
A failing air suspension system can significantly impact your Land Rover’s performance and safety. Here’s how:
● Reduced Ride Comfort: A malfunctioning air suspension system results in a rougher, less comfortable ride.
● Compromised Handling: Uneven suspension affects steering control and stability, making driving riskier.
● Increased Tire Wear: Uneven suspension can lead to irregular tire wear, reducing their lifespan.
● Higher Fuel Consumption: When suspension problems cause improper aerodynamics, fuel efficiency may decrease.
● Risk of Further Damage: Ignoring suspension issues can lead to additional damage to other components, such as axles and control arms.
Preventing Land Rover Air Suspension Problems
To extend the life of your air suspension system, follow these tips:
● Regularly check the system for leaks or worn parts.
● Keep the air suspension compressor clean and free of debris.
● Perform periodic diagnostic scans to detect issues early.
● Park on level ground to reduce strain on the suspension.
Benefits of Regular Maintenance
Like any mechanical system, air suspension requires proper maintenance and care to function optimally over time. Regular maintenance of your Land Rover’s air suspension system offers several benefits, including:
● Enhanced Ride Comfort: Ensures a smooth, stable, and comfortable driving experience.
● Prolonged Component Lifespan: Prevents premature wear and extends the durability of suspension parts.
● Improved Fuel Efficiency: A properly functioning system maintains optimal vehicle aerodynamics.
● Lower Repair Costs: Addressing minor issues early helps avoid expensive repairs in the future.
● Greater Vehicle Safety: Ensures stability, handling, and braking efficiency remain at peak performance.
Air Suspension Replacement vs. Repair
If your Land Rover’s air suspension system is failing frequently, you might consider a full replacement rather than repeated repairs. Here’s a cost breakdown:
● Air suspension repair cost: £300 – £500 (varies based on the issue).
● Full air suspension replacement: £1,000 – £3,000 (depend on Range Rover models).
● Air suspension kits for Land Rover can be an affordable alternative to replacing individual components.
Is an aftermarket kit a good idea?
Aftermarket air suspension kits can be a cost-effective solution. They may not offer the exact performance of OEM parts, but they can be a viable alternative if you’re on a budget.
