Factory Recommended Service Schedule

Primary Service Interval

Bentley's official service schedule for the 2023 Bentayga EWB is consistent across the lineup: once a year or every 10,000 miles, whichever comes first . In some international markets, the specified interval is 15,000 km .

The vehicle is equipped with a standard service interval indicator on the instrument cluster, which alerts the driver when scheduled maintenance is approaching .

Annual / 10,000-Mile Service Contents

At each scheduled visit, a comprehensive service is performed :

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

Progressive Service Schedule

As the vehicle accumulates mileage, additional service items become relevant:

Factory Warranty and Maintenance Plans

New Vehicle Warranty

Every new 2023 Bentley Bentayga EWB comes with comprehensive warranty coverage :

Complimentary Scheduled Maintenance

Bentayga SUV models enjoy 3 years/unlimited miles of included scheduled maintenance, with the first year of Bentley service being complimentary for the original owner . In some markets, the manufacturer may offer an optional extension to a 5-year/100,000 km maintenance plan .

Extended Warranty

Original owners can extend the factory warranty by two additional years. This extension is transferable to a private buyer and features unlimited mileage, unlimited claims value, Bentley roadside assistance, and is honored at any Bentley dealership .

Engine Oil Change Guidance

Oil Specifications

The 2023 Bentayga EWB's 4.0L twin-turbo V8 requires a premium, high-quality fully synthetic oil that meets Bentley's factory standards . Using the correct specification is critical for the longevity of the turbochargers and engine components.

Oil Change Interval

• Factory Recommendation: Every 12 months or 10,000 miles (or the local distance equivalent, e.g., 15,000 km) .
• Conservative Guidance: Some specialists recommend changing the oil more frequently, around 5,000-10,000 km (3,000-6,000 miles) or 1 year, especially for vehicles used primarily for short trips, in stop-start city driving, or in extreme climates .

A documented service history is essential. A low-mileage, well-maintained example may have a predicted residual value of approximately £88,025 after three years .

Air Filter Service

Engine Air Filter

The engine air filter protects the 4.0L twin-turbo V8 from dust and debris, preserving horsepower, torque, and fuel economy .

• Inspection: Recommended at every scheduled service .
• Replacement Interval: Typically every 15,000–30,000 miles, though more frequent checks are advised for those driving in dusty or high-pollen environments .
• Signs of a Bad Filter: Reduced acceleration, lower fuel economy, or unusual engine sounds may indicate a clogged filter .

Cabin Air Filter

The cabin air filter maintains the refined cabin atmosphere by removing pollen, dust, and roadway contaminants from the HVAC system . It is typically replaced during the annual service or when airflow is reduced.

Transmission Service

General Guidance

The 2023 Bentayga EWB is equipped with a sophisticated 8-speed automatic transmission. Unlike engine oil, transmission fluid does not have a standard mileage for all vehicles. The requirement to change the fluid depends on the specific driving conditions .

• General Recommendation: Many manufacturers suggest intervals between 30,000 and 60,000 miles for a transmission flush .
• Heavy-Use Guidance: For vehicles subjected to stop-and-go traffic, towing, or high-performance driving, more frequent service is recommended.
• Disclaimer: If shifting becomes rough, delayed, or is accompanied by unusual noises, the vehicle should be inspected immediately. Consult the owner's manual for the specific interval for your vehicle.

Battery Maintenance

The 2023 Bentayga EWB relies on a high-performance battery to power critical systems beyond just ignition, including electronics, advanced driver aids, and infotainment. A strong battery is vital for reliability and to protect complex electrical components .

• Lifespan: Battery life depends on driving patterns, climate, and accessory load; typical service intervals range from 3 to 6 years .
• Testing: Regular battery health checks during scheduled service visits are recommended to identify decline before a failure occurs .
• Replacement: The replacement process takes approximately 60–90 minutes, and often requires software reinitialization by a certified technician to ensure all systems recognize the new unit .

Brake System

Components and Wear

The 2023 Bentayga EWB demands high-performance braking components to match its luxury driving dynamics. The braking system is subject to significant stress due to the vehicle's weight and performance.

• Inspection: Brake pads, discs, and fluid condition should be inspected at every scheduled service.
• Brake Fluid: Replacement is typically recommended every 2 years, as brake fluid absorbs moisture over time and degrades braking performance.
• Rotor Wear: Front rotors handle a larger share of braking force and typically show wear sooner than rear rotors.

Suspension System

The 2023 Bentayga EWB features advanced air suspension as standard equipment, with automatic 4-corner level control and height-adjustable suspension.

Inspection and Maintenance

• Inspection: Air suspension components, including air springs, compressors, and height sensors, should be inspected at every annual service.
• Heavy-Use Guidance: For Bentayga models driven in challenging road conditions, more frequent inspections are recommended.

Long-Term Ownership Considerations

The 2023 Bentley Bentayga EWB is a vehicle that rewards diligent preventive maintenance. Key considerations for owners include:

• Specialist Care: Given the vehicle's complexity, service should be performed by certified Bentley technicians familiar with the brand's engineering .
• Service Documentation: Maintaining a comprehensive service history preserves resale value and provides documentation for warranty claims.
• Battery Maintenance: Proactive battery testing is recommended to avoid unexpected electrical issues .
• Proactive Inspections: Regular inspections by a qualified technician are recommended to identify wear issues early.
