Introduction

The 2010 Bentley Azure represents the pinnacle of British luxury motoring, powered by the legendary 6.75L twin-turbo V8 that defined Bentley for generations. As the final model year of the Azure line, this grand tourer convertible combines hand-crafted luxury with substantial performance.

Proper preventive maintenance is essential for preserving the performance, reliability, and value of this exceptional motorcar. This guide compiles factory-recommended service intervals, known technical considerations, and conservative owner guidance for the 2010 Azure. The vehicle is rear-wheel drive, and all maintenance guidance reflects this configuration.

Factory Recommended Service Schedule

Service Interval

The 2010 Bentley Azure follows a structured service schedule based on mileage or time, whichever comes first. The primary interval is annual service or every 10,000 miles (approximately 16,000 km) .

Annual / 10,000-Mile Service

Each scheduled visit includes the following baseline items :

• Engine oil and filter change with synthetic oil meeting Bentley specifications
• Tire rotation
• Replacement of the in-cabin pollen filter
• Replacement of windshield wipers and key fob battery as needed
• Thorough inspection of all vehicle mechanicals, including brake pads and discs, all fluid levels, visual inspection for leakage, and suspension component check

Following the vehicle inspection, owners are informed of any components not meeting specification, at which time they can approve any necessary repairs .

Service Schedule Progression

The Azure's service schedule typically progresses in a rotating series of service types, with the 2nd annual service being an intermediate service and the 4th annual being a major service . Service intervals are every 10,000 miles or 12 months .

Factory Warranty Coverage

Every new 2010 Bentley Azure came with :

• 3-year/unlimited mileage factory warranty covering basic, powertrain, corrosion, and roadside assistance
• Free scheduled maintenance for 36 months or 30,000 miles from the original purchase date
• Service interval warning system on the instrument cluster

Engine Oil Change Guidance

The 2010 Bentley Azure is equipped with the 6.75L twin-turbo V8, a powerhouse with substantial lubrication requirements.

Oil Capacity and Specifications

• Oil capacity: 9.0 liters with filter change
• Recommended oil: 0W-40 synthetic oil meeting Bentley specifications

Recommended Oil Change Interval

• Factory recommendation: Every 12 months or 10,000 miles
• Conservative owner guidance: Given the vehicle's age and the engine's sensitivity to oil quality, many specialists recommend more frequent changes, particularly if the car is driven infrequently

Oil Quality Notes

Regular oil changes are particularly important for the 6.75L V8. Using incorrect or infrequently changed oil can lead to significant engine issues.

Transmission Service Guidance

The 2010 Bentley Azure is a rear-wheel-drive vehicle with a 6-speed automatic transmission.

Service Schedule

Transmission oil is replaced as part of the regular annual service schedule . A transmission filter set is available as a service part for these models .

Conservative Owner Guidance

• If service history is unclear, consider having the transmission fully serviced by a specialist
• If shifting becomes rough, delayed, or accompanied by unusual noises, have the transmission inspected immediately

Spark Plug Timing

Technical Considerations

Spark plugs are typically replaced during major service intervals. Aftermarket options such as the DENSO Iridium TT and Champion Iridium plugs are available for the 2010 Azure, with some offering over 100,000 miles of service life .

The 6.75L V8 requires a full set of plugs. Service history from similar Bentley models of this era shows spark plug replacement often coinciding with major services .

Coolant Service Timing

Service Schedule

Coolant replacement is typically included in major service intervals. The cooling system capacity on the Azure is substantial, requiring 5L or more of coolant .

Coolant Type

The Azure uses a glycol-based antifreeze/coolant, typically a 50/50 mix of antifreeze and distilled water. A ready-to-use engine coolant providing protection against freezing, overheating, and corrosion is recommended .

Brake Fluid Recommendations

Service Schedule

Brake fluid is checked and replaced at scheduled intervals as part of the annual inspection.

• Conservative guidance: Flush brake fluid every 2 years to prevent moisture absorption and corrosion
• Brake fluid type: DOT 4 brake fluid is specified for these models

Hydraulic System

The Azure uses a hydraulic system for its power folding top, steering, and suspension.

Fluid Service

• Hydraulic system fluid: Regular inspection and replacement as needed
• Power folding top: Owners should note that the convertible top should be assisted when closing using the provided hand hold on the interior

Known Technical Service Bulletins (TSBs)

Several Technical Service Bulletins have been documented for the 2010 Bentley Azure, highlighting areas requiring particular attention during routine service :

Additional Maintenance Considerations

Service History Importance

Maintaining a comprehensive service history is critically important for the 2010 Azure. Well-maintained examples with full main dealer or specialist service history are significantly more desirable and valuable.

Battery Maintenance

The Azure requires proper battery maintenance. The vehicle should be kept on a trickle charger if not used weekly to maintain battery health and prevent electrical system issues. A TSB (2051562.4) specifically addresses 12V battery condition checks .

Suspension and Rubber Components

With the vehicle now over 15 years old, rubber components require regular inspection. Suspension components, including air springs, should be checked as part of routine service. A TSB (2053492.4) covers air spring fault finding .

High-Mileage Maintenance Planning

For 2010 Azure examples approaching or exceeding 75,000 miles:

1. Major service: Comprehensive inspection including all service types
2. Coolant flush: Complete system flush with fresh coolant
3. Brake fluid flush: Full hydraulic system flush
4. Transmission service: Full fluid and filter service by a specialist
5. Spark plugs: Replace if not done within the last 30,000-50,000 miles
6. Battery inspection: Check condition and replace if showing signs of age
7. Air suspension inspection: Check for signs of leakage or degradation

Long-Term Ownership Considerations

The 2010 Bentley Azure rewards diligent maintenance. As a low-production, hand-built motorcar:

• Engine misfires: The engine is known to be susceptible to poor running and misfires, as documented in TSB 2051187.1 and 2051187.3 . Regular maintenance and prompt attention to running issues are essential
• Brake noise: Brake noise is a documented area of concern (TSB 2052785.3) . Regular brake inspection is essential
• Battery maintenance: Regular battery condition checks are recommended (TSB 2051562.4)
• Specialist care: Given the vehicle's complexity, using qualified specialists familiar with the Azure is strongly recommended
• Documentation: Maintain a comprehensive service history to help preserve resale value
