Land Rover & Range Rover Diagnostics: Common Faults and Warning Lights
Is your Land Rover displaying a dashboard warning light, losing power or developing an intermittent fault? Modern Land Rover and Range Rover vehicles rely on complex electronic systems, making accurate diagnosis essential before carrying out repairs.
At APB Trading, we provide specialist Land Rover diagnostics and repairs from our workshop in Hartlebury, near Kidderminster, Worcestershire. Our team investigates engine, gearbox, suspension, braking and electrical faults across the Land Rover range.
What Does a Land Rover Diagnostic Test Check?
A Land Rover diagnostic test uses specialist equipment to identify fault codes, examine live vehicle data and investigate problems affecting electronic and mechanical systems.
At APB Trading, we use Autologic diagnostic equipment alongside mechanical and electrical testing to help identify the underlying cause of a fault.
Importantly, a fault code doesn’t always identify the component responsible. Further investigation may be necessary to establish the correct repair rather than simply clearing a warning light or replacing parts unnecessarily.
Common Land Rover and Range Rover Faults
Engine Management Warning Lights
An illuminated engine management light can indicate problems with sensors, fuel delivery, emissions systems or engine performance.
Common symptoms include reduced power, rough idling, increased fuel consumption and difficulty starting.
If the warning light is flashing or the engine is running badly, stop driving when safe and seek professional advice.
Air Suspension Problems
Air suspension faults are common reasons for diagnostic enquiries on Land Rover Discovery and Range Rover models.
Symptoms can include:
- Suspension warning messages
- Vehicle sitting lower on one side
- Suspension failing to raise or lower
- Vehicle dropping overnight
Potential causes include air leaks, compressor problems, faulty height sensors and electrical issues.
Automatic Gearbox and Transmission Faults
Range Rover and Land Rover automatic gearbox problems may cause jerky gear changes, hesitation, transmission warnings or restricted performance.
These symptoms can result from electronic faults, transmission-fluid problems or mechanical wear.
APB Trading provides gearbox diagnostics and repairs in-house, helping identify the problem before recommending the appropriate work.
ABS and Electronic Braking Faults
ABS, traction control, hill descent control and stability system warnings can sometimes appear together.
A faulty sensor or electronic component may trigger several warning messages, making specialist diagnostic testing particularly useful.
If braking performance is affected, avoid driving the vehicle until it has been assessed.
DPF and Emissions Faults
Diesel Land Rover models can develop diesel particulate filter (DPF) and emissions-related problems.
Warning signs include reduced power, increased fuel consumption, DPF warnings and unsuccessful regeneration cycles.
Diagnostic testing helps establish whether the problem involves the DPF itself, a sensor or another engine-related component.
Electrical and Intermittent Problems
Electrical faults can cause multiple warning lights, starting difficulties, battery problems or intermittent failures.
These issues can be difficult to identify without suitable diagnostic equipment and experience working with Land Rover electronic systems.
Why Choose a Land Rover Diagnostic Specialist?
Land Rover and Range Rover vehicles have sophisticated electronic systems that may require manufacturer-specific diagnostic procedures.
A basic fault-code reader can provide useful information, but it may not access every system or identify the underlying problem.
At APB Trading, our experience with Land Rover vehicles allows us to combine specialist diagnostic testing with mechanical and electrical investigation. We also provide comprehensive Land Rover servicing and repairs at our Hartlebury workshop.
We can also carry out the necessary repairs at our workshop, avoiding the need to arrange separate diagnostic and repair appointments.

Frequently Asked Questions
How much does a Land Rover diagnostic test cost?
The cost depends on the fault and the investigation required. Some issues can be identified quickly, while intermittent electrical or mechanical problems may require additional testing. Contact APB Trading for diagnostic pricing.
Can I drive my Range Rover with an engine management light on?
It depends on the warning and the vehicle’s behaviour. A flashing warning light, significant loss of power or unusual engine operation requires immediate attention. Stop safely and seek professional advice. Even if the vehicle drives normally, the fault should be investigated.
Why is my Land Rover showing several warning lights?
Several warnings can sometimes originate from one underlying problem, such as a faulty sensor, low battery voltage or an electronic communication fault. Diagnostic testing can help identify the cause.
Can diagnostics identify Range Rover gearbox problems?
Yes. Diagnostic testing can identify transmission fault codes and examine operating data. However, some mechanical gearbox problems require additional inspection because they may not generate a fault code.
Why does my Land Rover keep showing a suspension fault?
Possible causes include air leaks, compressor problems, faulty height sensors or electrical faults. If the vehicle is sitting unevenly or struggling to raise, a specialist inspection can help identify the problem.
