The Foxwell NT520 is a powerful diagnostic tool that can be used to calibrate the air suspension system on Land Rover vehicles. If you’re experiencing issues with your air suspension, such as uneven ride height or suspension fault messages, the NT520 can help you diagnose and resolve the problem. This guide will walk you through the steps involved in using the Foxwell NT520 for Land Rover air suspension calibration.
Understanding Land Rover Air Suspension Systems
Before diving into the calibration process, it’s essential to understand the basics of Land Rover air suspension systems. Unlike conventional steel spring suspensions, air suspension utilizes adjustable air springs to control ride height and comfort. These systems offer several advantages, including:
- Adjustable Ride Height: Allowing drivers to raise or lower the vehicle based on terrain or load requirements.
- Improved Ride Quality: Air springs provide a smoother ride compared to traditional springs.
- Load Leveling: The system automatically adjusts to maintain a level ride height regardless of passenger or cargo weight.
However, air suspension systems can also encounter issues, often requiring diagnostic tools like the Foxwell NT520 for troubleshooting and calibration.
Common Land Rover Air Suspension Problems
Various factors can lead to air suspension problems in Land Rover vehicles. Some common issues include:
- Leaking Air Springs: Over time, air springs can develop leaks, causing the vehicle to sag or sit unevenly.
- Faulty Height Sensors: These sensors monitor the vehicle’s ride height and relay information to the suspension control module. Malfunctioning sensors can lead to inaccurate readings and suspension problems.
- Compressor Failure: The air compressor is responsible for pumping air into the springs. A failing compressor can result in a loss of ride height or slow suspension response.
- Electrical Issues: Wiring problems or faulty connections within the air suspension system can also trigger malfunctions.
How the Foxwell NT520 Can Help
The Foxwell NT520 is a professional-grade diagnostic scanner that offers a range of functions for Land Rover vehicles, including:
- Read and Clear Fault Codes: The NT520 can retrieve and clear diagnostic trouble codes (DTCs) related to the air suspension system.
- Live Data Monitoring: View real-time data from various sensors, including ride height sensors, pressure sensors, and the suspension control module.
- Bi-Directional Control: Perform active tests on air suspension components, such as activating the compressor or individual air springs.
- Calibration Procedures: Access and perform calibration routines for the air suspension system.

Calibrating your Land Rover’s air suspension with the Foxwell NT520 is a straightforward process. Here’s a step-by-step guide:
- Connect the NT520: Begin by connecting the Foxwell NT520 to your vehicle’s OBD-II port. The port is usually located under the dashboard on the driver’s side.
- Power on the Device: Turn on the ignition but do not start the engine. This will power up the NT520 and establish communication with your Land Rover’s onboard computer.
- Select Land Rover Software: Navigate through the NT520’s menu and select the appropriate software for your specific Land Rover model.
- Choose Air Suspension System: From the list of available systems, select “Air Suspension” or a similar option.
- Initiate Calibration Procedure: Locate and select the “Calibration” or “Reset” function within the air suspension menu.
- Follow On-Screen Instructions: The NT520 will guide you through the calibration process, which may involve specific steps such as adjusting ride height or driving the vehicle a short distance.
- Complete Calibration: Once the calibration process is complete, the NT520 will confirm the successful reset. You can then clear any stored fault codes.
Note: The exact calibration procedure may vary slightly depending on the specific Land Rover model and year. Always refer to the NT520 user manual and your vehicle’s service information for detailed instructions.
Tips for Successful Calibration
- Ensure Level Ground: Park your Land Rover on a flat, level surface before initiating the calibration process.
- Disable Suspension Settings: If your Land Rover allows for adjustable suspension settings, such as “Comfort” or “Sport” modes, disable them before calibration.
- Avoid Interruptions: Do not interrupt the calibration process once it has begun. Ensure the vehicle’s battery has sufficient charge.
- Consult a Professional: If you encounter any difficulties or are unsure about any step, consult a qualified Land Rover technician or a reputable automotive repair shop.
