Factory Recommended Service Schedule

Primary Service Interval

Bentley's official service schedule for the 2018 Bentayga is clear and consistent: every 12 months or 16,000 km (approximately 10,000 miles), whichever comes first . This interval applies across the entire 2018 Bentayga range, including the W12, V8, and Diesel variants.

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 typically performed :

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

Factory Warranty and Maintenance Plans

New Vehicle Warranty

Every new 2018 Bentley Bentayga 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 .

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 .

Bentley also offers a Certified Pre-Owned warranty program following a 180-point inspection, which provides coverage for a minimum of one year with no mileage restrictions .

Engine Oil Change Guidance

Oil Specifications

The 2018 Bentayga's engines require high-quality synthetic oil meeting Volkswagen Group specifications. The 16,000 km (10,000-mile) oil change interval assumes an approved synthetic oil product has been used .

Engine Capacities by Variant

Oil Change Interval

• Factory recommendation: Every 12 months or 16,000 km (10,000 miles)
• Conservative owner guidance: For vehicles used primarily in stop-start city driving, short trips, or extreme temperature conditions, specialists recommend more frequent changes. Even if the mileage is low, an oil change should never be delayed beyond 12 months, as synthetic oil can break down over time.

Air Filter Service

The engine air filter protects the W12, V8, or Diesel engine from dust and debris, preserving horsepower and fuel economy. A clogged air filter restricts airflow, causing the engine to consume more fuel and potentially leading to reduced performance.

• Inspection: Recommended at every service
• Replacement interval: Varies with driving conditions; Bentley Atlanta recommends more frequent checks for dusty or high-performance driving
• Importance: Regular replacement maintains peak power, fuel economy, and turbocharger health

Transmission Service

Transmission Specifications

The 2018 Bentayga is equipped with an eight-speed automatic transmission . Transmission fluid level and condition are typically checked at scheduled services. A full transmission fluid and filter service may be recommended at higher mileages depending on driving conditions.

Warning Signs

If shifting becomes rough, delayed, or accompanied by unusual noises or lurching, have the transmission inspected immediately.

Brake System

Brake Components

The 2018 Bentayga features substantial braking systems engineered for confident stopping despite the vehicle's considerable mass. Brake pads and discs should be inspected at every scheduled service . Due to the vehicle's weight and performance capability, brake components may wear more quickly than on lighter vehicles.

Brake Fluid

Brake fluid absorbs moisture over time and requires periodic replacement to maintain optimal braking performance. A conservative approach is to flush brake fluid every 2 years regardless of mileage.

Long-Term Ownership Considerations

The 2018 Bentley Bentayga is a vehicle that rewards diligent preventive maintenance. Key considerations for owners:

• Specialist care: Given the vehicle's complexity, service should be performed by certified Bentley technicians or specialists familiar with the brand's engineering.
• Service documentation: Maintaining a comprehensive service history preserves resale value and provides documentation for warranty claims.
• Battery maintenance: The Bentayga's advanced electrical systems require proper battery maintenance; trickle charging is recommended for vehicles not used weekly.
• Air filter maintenance: Regular inspection and replacement of the engine air filter is essential for maintaining the performance of the turbocharged engine .
