Service Interval Summary

Service Documentation

The official owner's manual is a critical document to have with the vehicle. It details important operational instructions and maintenance schedules .

Engine Oil Service

Specifications

The 2005 DB9 Volante is powered by a 5.9L V12 engine factory-rated at 450 hp and 420 lb-ft of torque . While the exact oil capacity for the 2005 model year is not universally specified, it is estimated to be around 10.4–11.0 liters (this is not the 13.1-liter capacity used in later AM11 engines).

Oil Change Interval

The factory-recommended oil and filter change should be performed at the initial 1,000-mile service and subsequently every 12 months or 10,000 miles . A 2005 DB9 Volante with 29k miles had an oil change performed in 2024, highlighting the importance of regular service .

Owner Oil Level Check

Check the engine oil level regularly. Running the engine with oil below the lower mark or above the upper mark can cause serious engine damage.

Brake Fluid Service

Replacement Interval

The factory service schedule indicates brake and clutch fluid replacement at the 20,000-mile / 24-month interval . A documented 2005 DB9 Volante with 29k miles had a brake fluid flush performed in 2024 . This safety-critical service should not be deferred, as brake fluid absorbs moisture over time, reducing its boiling point and potentially leading to brake fade under hard use.

Transmission Service

Automatic Transmission

The 2005 DB9 Volante is primarily equipped with a six-speed ZF Touchtronic automatic transaxle with a limited-slip differential . The gearbox is controlled via buttons on the dashboard and can be shifted manually through steering wheel-mounted paddle shifters .

Manual Transmission (Rare Option)

A 6-speed manual transmission was available as a rare option on the DB9 Volante. Manuals tend to be more desirable for enthusiasts but require additional maintenance considerations . Around 15,000 miles between clutch changes is considered normal for manual DB9s . Check for crunching or resistance when changing into second gear, as this may indicate hard use .

Cooling System Service

The cooling system should be inspected at each regular service interval. A documented 2005 DB9 Volante had its front engine resealed and the drive belt replaced in October 2022, at approximately 29k miles .

Volante-Specific Care

Convertible Roof Mechanism

The DB9 Volante's electric soft top is a complex mechanism requiring regular attention:

• Inspect roof operation during each service .
• Check for tears in the fabric .
• Ensure drains are clear to prevent water ingress.
• Fixing the top can be a labour-intensive job to rectify .

Body and Chassis

The DB9 features a mix of aluminum and composite body panels installed over an extruded aluminum spaceframe . While corrosion is less of a concern than with steel-bodied cars, regular inspection of suspension components and subframe bolts is important.

Extended Maintenance Guidance

For long-term ownership planning, the following additional maintenance items should be considered:

Note: Always verify exact intervals for your specific model in the official owner's manual or service book.

The DB9 features a timing chain rather than a timing belt and does not require scheduled replacement.

Common Issues to Monitor

Ignition Coil Packs

Some owners have reported issues with faulty coil packs. A misfire or hesitation when accelerating are the warning signs to watch for . A 2005 DB9 Volante had its ignition coils replaced in 2022 .

Recalls

• Battery-supply cable recall: A recall regarding a battery-supply cable that could short circuit on the passenger seat affected cars built in the early part of 2007 .
• Parking brake recall: There was a recall on early examples for an issue with the parking brake not engaging .
• Subframe and suspension recalls: Two separate recalls were carried out regarding issues with the subframe-assembly bolts and front suspension-arm cam bolts .

Running Costs

The DB9 is a costly car to run. Rear tyres tend to wear out more quickly than fronts, and brake pads require regular replacement . Fuel consumption is approximately 13 mpg city / 18 mpg highway.
