The 2008 Aston Martin DB9 Volante represents a pinnacle of open-top grand touring, powered by a hand-built 5.9L V12 engine.

The manufacturer recommends a structured maintenance schedule divided into 10,000-mile (16,000 km) or 12-month intervals, whichever comes first . The 2008 DB9 is covered by a 3-year, unlimited mileage vehicle warranty from first registration . It is the owner's responsibility to ensure the vehicle is maintained correctly and in accordance with the manufacturer's service schedules.

Factory Service Schedule

Primary Service Interval Overview

The 2008 DB9 follows a structured annual service schedule. The service schedule is built around 10,000-mile (16,000 km) or 12-month intervals .

131-Point Inspection

At each major service, technicians perform a complete factory 131-point maintenance procedure covering all major vehicle systems including engine, transmission, fuel system, cooling system, suspension, brakes, and electrical systems .

Service Indication Warning

The vehicle features a service interval warning that alerts the owner when scheduled maintenance is due .

Brake Fluid Service

Brake fluid is hygroscopic—it absorbs moisture over time, which lowers its boiling point and compromises braking performance.

Factory Schedule:

• Replacement Interval: Every 12 months
• Check Interval: Weekly or during every annual service
• Fluid Specification: DOT 4 brake fluid
• System Capacity: Between Min. and Max. marks on the reservoir

Owner Guidance: A documented 15,000-mile DB9 Volante had its brake fluid changed in May 2024 . The brake fluid level should be checked regularly. If the brake fluid level is low, the dashboard brake warning light will come on .

Engine Oil Change Guidance

The 5.9L V12 requires regular synthetic oil changes at every 10,000-mile / 12-month service .

Key Specifications:

• Change Interval: Every 10,000 miles / 12 months
• Oil Type: High-performance synthetic oil as specified in the owner's manual
• Oil Filter: Replace with every oil change

Owner Guidance: Check the engine oil level every fourth fuel tank fill or weekly—whichever is the soonest . Running the engine with oil below the lower mark or above the upper mark can cause serious engine damage.

Suspension components are wear items that may require attention at higher mileages. A documented 50,000-mile example had its offside rear damper and nearside front damper replaced in August 2025 .
