The 2006–2009 Range Rover L322 combines a powerful V8 drivetrain, air suspension and extensive electronic systems in a luxury SUV that can still be rewarding to own many years later. However, age, mileage and maintenance history increasingly matter on these vehicles.

For owners, the important question isn’t simply whether an older L322 is reliable. It’s which systems need closer attention as the vehicle ages.

Air suspension faults, cooling-system problems, electrical issues and worn suspension components are among the areas worth monitoring. Dubai’s high temperatures can make the condition of cooling, electrical and rubber components particularly important.

Here are the main areas owners of 2006–2009 Range Rover L322 models should check.

Is the 2006–2009 Range Rover L322 Reliable?

A well-maintained L322 can continue to provide strong performance and comfort, but condition matters more than mileage alone.

By this age, deterioration of hoses, seals, bushes, electrical connections and suspension components can create problems even on vehicles that have covered relatively modest mileage.

Maintenance history therefore matters. An L322 with documented preventive maintenance and properly diagnosed repairs can be a very different ownership proposition from one that has received only basic servicing.

Owners should pay particular attention to:

• Air suspension operation
• Cooling-system condition
• Battery and charging-system health
• Fluid leaks
• Suspension bushes and joints
• Engine warning lights
• Transmission behaviour
• Unusual noises during cold starts and driving

Finding deterioration before it causes a secondary failure is especially important on an ageing luxury SUV.

1. Air Suspension Problems

The L322’s electronic air suspension is one of the features responsible for its ride quality and adjustable ride height. As the system ages, however, air leaks and component wear can affect its ability to maintain the correct height.

Potential trouble areas include air struts, air lines, valve components, height sensors and the suspension compressor.

Signs of L322 Air Suspension Trouble

Watch for:

• One corner sitting lower than the others
• Vehicle height dropping after being parked
• Slow suspension raising
• Compressor operating frequently
• Suspension warning messages
• Vehicle remaining at an incorrect ride height
• Uneven ride height from side to side

A vehicle that sinks while parked doesn’t automatically need a new compressor. A leak elsewhere in the system can force the compressor to work more frequently, so replacing components without diagnosing the source of pressure loss can lead to unnecessary repairs.

A proper inspection should determine where the system is losing pressure and why before parts are replaced.

2. Cooling System Problems and Coolant Leaks

Cooling-system condition deserves particular attention on an older L322, especially in Dubai.

Hoses, seals, connections, the thermostat, water pump and other cooling-system components should be inspected for deterioration or leakage as the vehicle ages.

Small coolant losses shouldn’t simply be topped up repeatedly. A gradual leak can eventually reduce the system’s ability to control engine temperature.

Warning Signs That Shouldn’t Be Ignored

Arrange an inspection if you notice:

• Falling coolant level
• Coolant underneath the vehicle
• Sweet coolant smell after driving
• Temperature increasing above normal
• Cooling fan running unusually hard
• Visible residue around hoses or connections
• Repeated low-coolant warnings

If the engine begins overheating, continuing to drive can turn a cooling-system repair into a much more serious engine problem.

The cause of the temperature increase should therefore be diagnosed rather than assuming that replacing a single component will solve it.

3. Age-Related Electrical Problems

The L322 contains numerous interconnected electronic systems controlling everything from engine management and suspension to comfort and infotainment functions.

On an ageing vehicle, an apparently unrelated collection of warning messages can sometimes originate from a common electrical problem.

Possible symptoms include:

• Intermittent dashboard warnings
• Slow or difficult starting
• Infotainment problems
• Central locking faults
• Suspension warnings
• Battery discharge
• Electrical features working intermittently
• Multiple warning lights appearing together

Why Battery Condition Matters

Before diagnosing several electronic modules individually, battery voltage and charging-system performance should be checked.

Modern vehicle electronics depend on stable voltage. A weak battery or charging problem can sometimes produce multiple faults that appear more serious than the underlying issue.

Proper diagnosis should therefore begin with the basics: battery condition, charging output, fault-code scanning and inspection of relevant wiring or connections.

Replacing electronic modules solely because a fault code mentions them can become unnecessarily expensive.

4. Suspension Bush and Front-End Wear

The L322 is a large, heavy SUV. Over time, suspension bushes, joints and related components can wear and affect how the vehicle feels on the road.

Common symptoms of suspension wear can include:

• Knocking over bumps
• Steering vibration
• Uneven tyre wear
• Loose or vague steering
• Vehicle pulling to one side
• Reduced stability during braking
• Clunks when changing direction

Air suspension and mechanical suspension wear should be treated as separate diagnostic areas. A Range Rover can maintain its correct ride height while still having worn bushes or joints.

A physical suspension inspection can identify excessive movement before it causes additional tyre wear or affects alignment.

5. 4.2 Supercharged and 4.4 V8 Engine Issues

The 2006–2009 petrol L322 range included naturally aspirated 4.4-litre V8 and 4.2-litre supercharged V8 configurations.

Rather than assuming every warning light indicates major internal engine damage, diagnosis should begin with the vehicle’s symptoms, stored fault codes, fluid condition and maintenance history.

Owners should pay attention to:

• Oil or coolant leaks
• Rough idle
• Unusual engine noises
• Loss of power
• Check-engine warnings
• Misfires
• Abnormal exhaust smoke
• Increasing oil or coolant consumption
• Unusual supercharger noise on applicable models

With an older V8, leaks that initially appear minor can become more significant with time. Identifying the actual source is preferable to replacing multiple seals or components based only on where fluid becomes visible underneath the engine.

The 4.2 Supercharged model also adds supercharger-related hardware, making unusual noises or changes in boost and engine performance worth investigating rather than ignoring.

6. Transmission and Drivetrain Behaviour

Transmission behaviour should also be evaluated when inspecting or maintaining an older L322.

Watch for:

• Delayed engagement
• Harsh gear changes
• Shuddering
• Hesitation during acceleration
• Transmission warning messages
• Unusual drivetrain noises
• Fluid leaks

Not every shift-quality problem automatically means that the complete transmission requires replacement or rebuilding. Electronic faults, fluid condition and other drivetrain components can sometimes produce overlapping symptoms.

Diagnostic scanning and a road test are therefore important before deciding on a major transmission repair.

What Should You Inspect on a 2006–2009 L322?

If you already own an L322 — or you’re considering buying one — a comprehensive inspection should go beyond a basic engine check.

A useful inspection should cover:

Area	What to Check
Air suspension	Ride height, leaks, compressor operation and warning messages
Cooling system	Coolant level, leaks, hoses and operating temperature
Engine	Fluid leaks, noises, misfires and stored fault codes
Electrical system	Battery, charging performance and electronic faults
Mechanical suspension	Bushes, joints, steering play and tyre wear
Transmission	Shift quality, engagement and stored faults
Brakes	Pad/disc condition and braking behaviour
Underbody	Fluid leaks, damaged components and deterioration

For a vehicle purchase, a pre-purchase inspection can be particularly valuable. Clearing a warning light shortly before a sale doesn’t necessarily mean that the underlying fault has been repaired, so diagnostic history and the vehicle’s physical condition should be considered together.

Maintaining an Older Range Rover L322 in Dubai

Dubai places additional demands on an ageing vehicle.

High ambient temperatures increase the importance of cooling-system performance, while prolonged heat can accelerate deterioration of rubber and plastic components. Air-conditioning performance is also considerably more important locally than it may be in milder climates.

For an older L322, preventive maintenance should therefore include regular attention to:

• Cooling-system condition
• Engine and transmission fluid leaks
• Battery and charging performance
• AC performance
• Suspension components
• Tyres and alignment
• Rubber hoses and seals

Preventive inspection is usually more useful than waiting for a warning message or breakdown before investigating an ageing component.
