2005 Aston Martin DB9 5.9L Petrol · AM05 TAB

The vehicle is currently roadworthy following a pass in June 2025, but the maintenance trend shows signs of recent instability regarding electronic systems. The most recent test recorded a failure at 43,568 miles due to an inoperative engine malfunction indication lamp and an active TPMS warning. While these issues were rectified to secure the subsequent pass, the appearance of these faults suggests potential sensor failure or electrical module malfunction that may require further diagnostic attention to ensure long-term reliability of the management systems. The mileage profile is exceptionally low for a 21-year-old vehicle, averaging approximately 2,075 miles per year. Between June 2022 and June 2025, the car covered 8,385 miles, indicating a consistent pattern of low-intensity use rather than high-mile wear-and-tear. This low usage often implies the vehicle has sat for extended periods, which frequently leads to the degradation of rubber-based components, dry seals, and brake fluid contamination despite the low mechanical wear expected on the engine and drivetrain. A physical inspection must prioritise on the electronic faults flagged in the 2025 failure. The tester previously noted disconnected rear brake pad limit sensors in 2022 and a discoloured front indicator in 2023, suggesting minor attention to detail regarding wiring loom and connector corrosion. Given the low mileage, the buyer should specifically inspect for brake corrosion on the discs and perished in the suspension bushings, as the alloy guards mentioned in the 2023 record prevented a full inspection of the undercarriage and structural integrity.
