Displayed a suspension warning and bounced while driving.
We reattached a dislodged compressor pressure line, restored inflation, and confirmed normal operation on a road test. An overnight check then revealed leaking front air struts; replacement and ball-joint inspection were recommended.
A suspension warning light and an unusually bouncy ride brought this 2009 Land Rover Range Rover Sport HSE to Charlie’s Foreign Car.
Our inspection confirmed the customer’s concern: the air suspension was completely collapsed. As the vehicle entered the shop, the technician could hear air escaping near the suspension compressor.
That sound led to the first finding—but an overnight check would reveal another problem requiring attention.
A warning light, low ride height, or poor ride quality can have several possible causes:
Electrical supplies, fuses, relays, and fitting security also deserve consideration. Air-suspension specialist Arnott includes these areas in its compressor diagnostic checklist and emphasizes checking that air lines are seated to the proper depth.
Charlie’s Foreign Car removed the compressor cover and checked the accessible connections. The pressure line from the pump had become dislodged.
The compressor appeared to have been replaced recently, and the other connections appeared secure. The technician suspected that the pressure line had not been seated properly in its ferrule—the fitting component that helps retain the line—during assembly.
That remained the technician’s assessment rather than a confirmed explanation of how the line became detached.
Charlie’s Foreign Car reattached the air line and allowed the suspension to inflate.
The technician then performed a road test and confirmed that the suspension operated normally. Reconnecting the line restored the system’s ability to raise the vehicle during that test.
The technician also documented a condition to monitor: if the line becomes detached again, the compressor would require replacement because of a suspected faulty ferrule connection.
The successful road test was an important result, but it was not the end of the inspection.
After the vehicle sat overnight, Charlie’s Foreign Car found that the front air struts were leaking. When the engine started, the system automatically corrected the vehicle’s level.
That automatic correction did not mean the leaks had resolved. It showed that the system could raise the vehicle again despite the pressure loss found during the overnight check.
Air leaks can also increase compressor workload as the system tries to maintain pressure, making the remaining leaks important to address.
Based on the overnight findings, Charlie’s Foreign Car recommended:
A four-wheel alignment was also listed in the service information. The supplied notes do not confirm completion of the front-strut replacement, ball-joint inspection, or alignment.
This Range Rover had a disconnected compressor pressure line and leaking front air struts. Reattaching the line restored normal suspension operation on the road test, while the overnight inspection identified the remaining pressure-loss concern.
If your Range Rover sits low, develops a bouncy ride, or displays a suspension warning, contact Charlie’s Foreign Car to schedule an inspection.
