As a proud Range Rover owner myself, I know how frustrating it can be when the air suspension fails to raise the vehicle to the desired height.

Why my Range Rover air suspension won’t raise? It may be due to a faulty air compressor, leaking air springs, or issues with the height sensors. Diagnostic tools can help identify the issue, but professional repair service is often recommended.

If you are facing a similar issue, here’s everything you need to know to diagnose and fix the problem.

Signs and symptoms

When the Range Rover’s air suspension system fails to raise the vehicle, you may notice one or more of the following symptoms:

  • The vehicle sits lower than normal on one or both sides.
  • The suspension warning light on the dashboard is illuminated.
  • The vehicle’s suspension feels stiff and bumpy.
  • The onboard diagnostic (OBD) system displays error codes related to the suspension system.

List of possible OBD codes

Here are some of the most common OBD codes related to Range Rover air suspension issues:

  • C1A20: Pressure Increases Slowly when Filling Air Spring
  • C1A13: Pressure Does not Decrease When Venting Gallery
  • C1A10: Air Spring Front Left General Failure
  • C1A11: Air Spring Front Right General Failure
  • C1A12: Air Spring Rear Left General Failure
  • C1A13: Air Spring Rear Right General Failure

Common causes

There are several reasons why Range Rover air suspension may fail to raise the vehicle. Here are some of the most common causes:

  1. Faulty Air Springs: The air springs may develop cracks or leaks, causing air to leak out and preventing the suspension from raising the vehicle.
  2. Failed Compressor: The compressor may fail due to a broken piston ring or a faulty valve, preventing it from pumping air into the suspension system.
  3. Blown Fuse: A blown fuse in the air suspension system can cut power to the compressor, preventing it from raising the vehicle.
  4. Faulty Height Sensors: The height sensors may fail to detect the vehicle’s height accurately, resulting in the suspension system failing to raise the vehicle.
  5. Corroded Relay: A corroded relay can prevent the compressor from receiving power, preventing it from raising the vehicle.

Can it be fixed without a mechanic?

If the problem is minor and doesn’t require replacing any parts, you can fix the Range Rover air suspension issue yourself.

The first port of call is resetting your Range Rover’s air suspension.

We recommend you seek the assistance of a qualified Range Rover mechanic for safety reasons if you’re unsure of any diagnosis.

Parts you’ll need to fix it

Here are the parts you’ll need to fix the Range Rover air suspension:

  • Replacement Air Springs
  • Replacement Compressor
  • Replacement Height Sensors
  • Electrical Connectors and Wires
  • Fuses

Tools you’ll need to fix it

Here are the tools you’ll need to fix the Range Rover air suspension system:

  • Floor Jack
  • Jack Stands
  • Socket Set
  • Torque Wrench
  • Multimeter
  • Wire Stripper
  • Soldering Iron

How to fix it

Here is a step-by-step guide to fixing the air suspension system in your Range Rover:

  1. Safely raise and support the vehicle on jack stands.
  2. Remove the faulty air springs and compressor after disconnecting all electrical connections and hoses.
  3. Install the new air springs and reconnect all electrical connections and hoses.
  4. Check all the fuses related to the air suspension and replace any blown fuses.
  5. Replace any corroded relays with new ones.
  6. Test the air suspension system and ensure that the vehicle raises and lowers effectively.
  7. Revisit the OBD system, clear all suspension-related codes, and check for any new codes.

Potential other alternative causes

While the causes listed above are some of the most common, other factors may cause the air suspension to fail to raise the vehicle.

It’s essential to have the system thoroughly checked by a qualified mechanic to identify the exact cause of the issue.

FAQs

What is causing my Range Rover’s suspension warning light to come on?

The most common reasons for the suspension warning light to come on are a failed compressor, faulty air springs, or a blown fuse in the air suspension system. Other potential causes include corroded relays, faulty height sensors, and wiring issues.

Can I drive my Range Rover if the suspension won’t raise?

It’s not recommended to operate the vehicle when the suspension fails to raise. It will cause additional stress on the other components such as axle joints, wheel bearing, and steering parts.

Is a Range Rover expensive to maintain?

Yes, Range Rovers can be expensive to maintain, especially if you don’t regularly maintain them. Servicing the air suspension system is a costly affair if you need to replace parts such as the air springs and compressor.

Summary

Fixing a Range Rover air suspension that won’t raise can be a complex and time-consuming process that requires technical expertise.

However, with proper diagnosis and accurate parts, you can fix the problem and restore your vehicle’s smooth ride.
