Factory Recommended Service Schedule

Primary Service Interval

Bentley's official service schedule for the 2014 Flying Spur is clear and consistent: maintenance is required once a year, or every 10,000 miles (approximately 16,000 km), whichever comes first . A 15,000 km interval is also referenced in some sources . This foundational requirement applies to all 2014 Flying Spur variants, including the W12 Mulliner specification models .

The vehicle is equipped with a standard service interval warning system on the instrument cluster that alerts the driver when scheduled maintenance is approaching.

Annual / 16,000 km Service Contents

At each scheduled visit, the following baseline items are recommended based on documented service records and specialist practice:

• Engine Oil & Filter: Replaced with Bentley-specification fully synthetic oil. A documented 2014 Flying Spur with 45,000 miles had its oil changed in July 2025 .
• Tire Rotation: All four tires rotated for even wear.
• Cabin Pollen Filter: Replaced. Documented examples show cabin air filter replacement performed between 2023 and 2024 .
• Engine Air Filter: Inspected and replaced as needed. Documented examples show engine air filter replacement performed between 2023 and 2024 .
• Windshield Wipers: Replaced as needed.
• Key Fob Battery: Replaced.
• Brake System: Comprehensive inspection of brake pads and discs. A documented 2014 Flying Spur with 45,000 miles had front brake pads and rotors replaced in September 2024 .
• Fluid Levels: All vehicle systems checked and topped up .
• Leakage Inspection: Visual inspection for fluid leaks.
• Suspension: Comprehensive inspection of all components, including the self-levelling air suspension system .
• Diagnostic Scan: Full vehicle systems check.

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

Brake Fluid Service

Fluid Type and Service Interval: The 2014 Flying Spur uses DOT-4 brake fluid .

• Inspection: Brake fluid level and condition should be inspected at every scheduled service (16,000 km / 12 months) .
• Replacement: Bentley recommends changing the brake fluid every 2 years (32,000 km / 24 months) to optimise braking performance .

DOT-4 fluid has a dry boiling point of 260°C and a wet boiling point of 180°C, providing excellent protection against high-temperature vapour lock and corrosion . A documented 2014 Flying Spur with 25,000 miles had its brake fluid changed in July 2025 .

Transmission Service

Service Considerations: The question of how often to change transmission fluid depends on several factors. Some modern transmissions are designed to never need a fluid change unless there is a leak or another problem, while others have a regular maintenance interval . It is important to follow Bentley guidelines on transmission maintenance .

Warning Signs: If shifting becomes rough, delayed, or is accompanied by unusual noises or lurching, have the transmission inspected immediately by a Bentley service center. A transmission rebuild can be a significant expense .

Spark Plug Timing

Replacement Interval: Spark plugs are a significant service item on the W12 engine. A documented 2014 Flying Spur with 48,391 miles had a full service including a spark plug change in June 2018 . This indicates that spark plug replacement is typically performed at major service intervals. Documented examples also show spark plugs being replaced between 2023 and 2024 .

Air Filter Service

Engine Air Filter: The engine air filter should be inspected at every oil change or annual service. Replacement intervals depend on driving conditions; urban or dusty environments shorten filter life . A documented 2014 Flying Spur with 45,000 miles had its engine air filter replaced between 2023 and 2024 .

Cabin Air Filter: The cabin pollen filter should be replaced during routine service to maintain cabin air quality. Documented examples show cabin air filter replacement performed between 2023 and 2024 .

Coolant Service

Replacement Interval: The cooling system is checked at every annual service for condition and proper protection levels. A documented 2014 Flying Spur with 25,000 miles had its coolant replaced in July 2025 . Coolant replacement is typically recommended at 5-7 years or according to the manufacturer's schedule. Using the correct coolant is essential for preventing corrosion and maintaining proper heat transfer in the high-performance W12 engine.

Service Documentation

Maintaining a comprehensive service history is critical for preserving the vehicle's resale value. The official instruction manual for the 2014 Flying Spur (part number 4W0 012 006 DQ) provides the definitive maintenance schedule and should be kept in the vehicle . A complete service history from a recognised Bentley specialist carries significant weight in the market .

A well-documented 2014 Flying Spur example shows the following service pattern :

• 1,987 miles - Bentley Surrey (Running-in service)
• 9,234 miles - Bentley Surrey
• 18,766 miles - Bentley Surrey
• 27,447 miles - Bentley Manchester
• 35,621 miles - Bentley Manchester
• 48,391 miles - Pescara International (Full service including brake fluid and spark plug change)

Long-Term Ownership Considerations

The 2014 Bentley Flying Spur rewards diligent and proactive maintenance. Key considerations for owners include:

Specialist Care

Given the vehicle's complexity, service should be performed by certified Bentley technicians or independent specialists with the right equipment and genuine parts. Bentley Atlanta recommends using OEM parts and following manufacturer service intervals to preserve vehicle health and resale value .

Brake Rotor Life

Rotor life depends on driving style and conditions; typical life ranges from 30,000 to 70,000 miles on high-performance luxury cars . Regular inspections help catch wear early and protect expensive brake components and pads .

Extended Warranty

Bentley's Certified Pre-Owned warranty program provides coverage for vehicles up to 10 years old with unlimited mileage, following a 180-point inspection.

Driving Habits and Storage

The Flying Spur benefits from regular use. For vehicles not used regularly, a trickle charger is recommended to maintain the advanced electrical systems. The manufacturer's recommended service schedule is the best way to prevent significant issues and expensive repairs.
