As an experienced Range Rover Sport owner with over 6 different Range Rover Sports, I’ve come across my fair share of issues with my RRS. One issue that I experienced numerous times was the suspension fault error code.
When I was driving on the main road home, and the Range Rover suddenly threw up a suspension fault error code and a red warning light along with special programs unavailable, followed by the engine management light for good measure!
In this article, we’ll look at some of the most common causes of suspension faults in Range Rover and explore some ways to fix the problem.
Key overview
- Suspension faults in Range Rovers can be caused by LOTS of factors.
- Some of the most common causes include worn-out suspension components, leaks in the air suspension system, and malfunctioning electronic control unit.
- The problem can often be fixed without a mechanic, but it may require some specialized tools and parts.
What does suspension fault mean on a Range Rover?
A “suspension fault” on a Range Rover means an issue with the Range Rovers suspension system, which is responsible for providing a smooth ride and maintaining tire contact with the road. A worn or damaged suspension component, a malfunctioning control module, or a problem with the air suspension system can cause this.
If this error is showing on your dashboard, you should first try resetting the air suspension before diving into what can be a nightmare trying to solve the problem.
Symptoms for a suspension fault
- The most obvious symptom of suspension fault is the car swaying and bouncing while driving.
- Other symptoms can include a rough ride, uneven tire wear, and suspension noise.
- A suspension fault error on your dashboard saying ‘suspension fault: normal height only.’
Most likely causes and faults
Before you spend time, money, and energy investigating all of these points, what I found fixed my Range Rover Sport’s 2009 suspension fault the battery was old and needed to be replaced as it wasn’t powering the electronic control unit (ECU) the desired amount.
I bought a new battery to replace the old one, upon checking and beginning to take the old battery out, I noticed the grounds weren’t properly grounded. Once I fitted my new battery and the grounds properly attached – the problem was SOLVED! The suspension, engine light, and special program fault message were cleared!
So, before going on to the next section of possible errors – please take your Range Rover down to a local garage and check the battery’s idle power and ignited power!
- Worn-out suspension components such as shocks, struts, and bushings are common causes of suspension faults.
- Leaks in the air suspension system can also cause problems. If the air suspension system is leaking, the car may not be able to maintain the correct height, causing a rough ride and uneven tire wear.
- Electronic control unit (ECU) malfunctioning can also cause suspension faults. The ECU is responsible for controlling the suspension, and if it malfunctions, it can cause the suspension to fail.
Can it be fixed without a mechanic?
- In many cases, yes. Many of the common causes of suspension faults in a Range Rover can be fixed with some basic tools and a bit of know-how.
- However, if the problem is caused by a major issue such as an ECU malfunction, it may be best to take the vehicle to a qualified mechanic.
Parts you’ll need
- Suspension components such as shocks, struts, and bushings
- Air suspension compressor and dryer
- Air suspension bags
- Electronic Control Unit (ECU) (if an ECU malfunction causes the problem)
Tools you’ll need
- A socket set
- Pliers
- A torque wrench
- A spring compressor tool
- A scan tool (for diagnosing an electronic control unit malfunction)
How to fix it:
- To replace worn-out suspension components, use a socket set to remove the old component and replace it with a new one.
- To fix leaks in the air suspension system, locate the leak and repair or replace the damaged part.
- To fix an ECU malfunction, use a scan tool to diagnose the problem and replace the ECU if necessary.
Potential other alternative causes
- A malfunctioning height sensor can also cause suspension faults. This can cause the car to sit too high or too low, causing a rough ride.
- A problem with the steering system, such as worn-out steering components, can also cause suspension faults.
Summary
Now you know what a suspension fault on a Range Rover means, it can include worn-out suspension components, leaks in the air suspension system, and malfunctioning electronic control units. In many cases, the problem can be fixed without a mechanic, but it may require some specialized tools and parts. If the problem persists, it’s best to take the vehicle to a qualified mechanic for further diagnosis and repair.
FAQs
How often should I check my suspension components for wear and tear?
It is recommended to have your suspension components inspected at least once a year or as per the recommendation of the car manufacturer. It is also important to have your suspension checked if you notice any symptoms of a fault, such as a rough ride or uneven tire wear.
Can worn-out suspension components affect my car’s handling?
Yes, worn-out suspension components can affect your car’s handling and make it feel unstable and unsafe to drive.
What is the average lifespan of an air suspension compressor?
The average lifespan of an air suspension compressor is around 100,000 miles. However, this can vary depending on usage and maintenance.
Can I fix an ECU malfunction myself?
It is possible to fix an ECU malfunction yourself if you have the proper tools and knowledge. However, it can be a complex task, and it is recommended to take the vehicle to a qualified mechanic for further diagnosis and repair.
