Yes, that dreaded light comes on when there’s an issue with your car’s suspension. That system is responsible for ensuring a smooth ride, no matter the terrain.

Read on to see what exactly the suspension warning light means, possible OBD codes, common causes, and how to fix it.

What models are affected?

Signs and symptoms

The suspension warning light appears on your dashboard when there’s a fault detected in your car’s suspension system.

This fault can range from a minor sensor issue to an entire collapsed suspension system, so it’s essential to understand the warning light’s color:

  • Amber/Yellow: when the light is yellow, it means your suspension system is faulty but still operational. You can drive as long as you’re careful and get the system checked soon.
  • Red: when the light is red, it means your suspension system has a severe fault that requires immediate attention. Typically, you will also experience reduced ride height or a rough ride.

List of possible OBD codes

When you see the suspension warning light, it’s best to use an OBD (On-Board Diagnostics) scanner to diagnose the fault.

Here are some of the most common OBD codes associated with the Range Rover Sport suspension warning light:

  • C1A13: Pressure does not decrease when venting gallery.
  • C1A20: Pressure does not increase when filling gallery.
  • C1A00: Control module.
  • C1131-14: Pressure does not decrease when venting gallery.
  • U0416: Invalid Data Received From Vehicle Dynamics Control Module.

Common causes

The suspension system is a complex one, and several factors can trigger the suspension warning light.

Some of the common causes include:

1. Faulty air struts

These are essential components of the suspension system responsible for adjusting the vehicle’s height and maintaining a smooth ride.

Over time, these air struts may experience leaks or become faulty, triggering the suspension warning light.

2. Dead battery

The Range Rover Sport relies on its battery to power several other systems, including the suspension system.

A dead battery or electrical fault can trigger the suspension warning light.

3. Damaged wiring

Over time, the harness responsible for conveying power to the suspension system may experience physical damage, leading to electrical faults and triggering the warning light.

Can it be fixed without a mechanic?

Depending on the severity of the fault, you may be able to fix the suspension warning light issue yourself.

For instance, if a dead battery causes a fault, you only need to jump-start the vehicle to clear the warning light.

However, some more severe faults require a mechanic’s attention, especially those caused by faulty air struts or damaged wiring.

Parts you’ll need to fix it

If the fault requires parts replacement, here are some essential components you might need:

  • Air strut
  • Wiring harness
  • Height sensor
  • Control module

Tools you’ll need to fix it

To diagnose and fix the suspension warning light issue, you’ll need some critical tools, including:

  • OBD Scanner
  • Jack and jack stands
  • Wheel chocks
  • Socket set
  • Screwdrivers
  • Multimeter
  • Wiring diagram

How to fix it

Depending on the root cause of the suspension warning light issue, here are some general steps to fix it:

  1. Use an OBD scanner to identify the specific fault code.
  2. If the fault is caused by a dead battery or electrical fault, jump-start the vehicle and clear the code with the OBD scanner.
  3. If the issue is caused by faulty air struts, replace the air strut with a new one.
  4. If the fault is due to a damaged wiring harness, follow the wiring diagram to locate the damaged wire and replace it.

Potential alternative causes

While the above covers common causes of suspension warning lights, it’s worth mentioning that sometimes, the fault may not be directly related to the suspension system.

Other factors may cause it, such as:

  • Damaged ABS sensor
  • Blocked suspension vents
  • Worn-out tires
  • Control module failures
