Range Rover air suspension faults and sagging

Which cars are affected?

This page covers Range Rover and Land Rover models fitted with air suspension. Not every model or version has it, so if you are not sure whether yours does, put the registration in the enquiry form and we will check.

For other work on these cars, see our Land Rover and Range Rover specialist page.

What are the symptoms?

• a “Suspension fault” message on the dashboard
• the car limited to a maximum of 30 mph
• the car sagging overnight
• a noisy compressor

When you book, tell us which message you saw, which corner drops and how long the car had been parked when you noticed.

What causes it?

Air suspension holds the car up on air springs, fed by a compressor through pipes and a valve block, with height sensors telling the system where the car sits. If air escapes, or the system cannot reach or read the right height, the car drops or the fault message appears.

The message does not tell you which part has failed. A sagging car points to a leak, but the leak can be in a spring or a pipe, and a noisy compressor does not by itself prove the compressor is the part at fault. We find out by testing, not by guessing.

How do you confirm the fault before fitting parts?

A fault code is not a repair, and a low car is not a diagnosis. Before we quote for any parts, we:

• read the fault codes stored by the suspension system with our diagnostic equipment
• leak-test the air springs and pipes, with leak-detection spray or a pressure-decay test
• check the compressor’s pressure readings and how long it has been running
• check the valve block
• read the height-sensor data

We then show you what we found and send a written price. No part is fitted until you give us your written approval.

What does the repair involve?

We replace the part the tests prove faulty, not the whole system.

• Leak. We replace the leaking air spring or strut, or repair the leak the test finds.
• Compressor. We replace it only when the tests prove it faulty.
• Ride height. After the repair we calibrate the ride height with our diagnostic equipment.

Air suspension work is done in-house. Once the work is done, we check that the car holds its height and the message has cleared, and verify the repair, including a road test where appropriate.

How long does an air suspension repair take?

It depends on what the tests find, on which part has failed, and some parts may need ordering.

Before any work starts, you get a written price and a promised time for your next update. If the car needs to stay with us, ask about a courtesy car when you book.

Is there a recall for Range Rover air suspension?

Whether a recall applies depends on the individual car, so check your registration on gov.uk. Recall work is done by Land Rover’s network, not by us.
