2009 Aston Martin V8 Vantage 4.7L Petrol · V8 WHG

Recurring failures regarding exhaust carbon monoxide levels define the recent testing history of this vehicle. While it passed its most recent inspection on 21 May 2026, this followed a failure the previous day for CO content exceeding manufacturer limits. A similar pattern occurred in April 2024, where the vehicle failed on both fast idle and idle CO levels before passing a day later. This suggests a persistent tendency for the engine to run rich or for the emissions system to struggle during the testing cycle. The recorded mileage of 28,963 miles is low for a seventeen year old vehicle, averaging approximately 1,704 miles per year. Such a low annual accumulation rate indicates the car has spent significant periods stationary or has been used very sparingly. Mechanically, this usage profile shifts the focus away from high-mileage wear on the drivetrain and suspension and toward the potential for degradation associated with inactivity. Given the repeated failures for exhaust carbon monoxide content, a prospective buyer should pay close attention to the engine's idling stability and throttle response. During a test drive, listen for any uneven idling or hesitation during acceleration, which could point to fuel trim issues or sensor malfunctions. Ensure the engine reaches operating temperature quickly and maintains a steady idle without hunting or surging. Because the MOT records are otherwise clear of advisories regarding the chassis, brakes, or suspension, the primary mechanical concern remains the emissions system. Verify that there are no signs of fuel leaks or exhaust leaks that could influence sensor readings. A professional diagnostic check of the engine management system would be prudent to determine if the recurring CO failures are linked to a specific component or are a result of the vehicle's low-use profile.
