2004 Audi A8 3.9L Diesel · OY04 CDK

The vehicle most recently passed its MOT on 12 May 2026 with no defects recorded. An analysis of the historical data indicates a stable maintenance trend, characterized by a consistent series of passes over the last several years. While there were intermittent advisories regarding tyre condition and steering components between 2023 and 2024, the absence of defects in the two most recent inspections suggests that the vehicle is currently being maintained to a satisfactory standard for roadworthiness. With a recorded mileage of 79,693 miles over a twenty-two year period, this Audi A8 has been used sparingly, averaging approximately 3,622 miles per year. While low mileage typically implies reduced wear on the engine and gearbox internals, it often introduces risks associated with prolonged periods of inactivity. For a luxury saloon of this vintage, low usage can lead to the degradation of rubber seals, the perishing of tyres, and the accumulation of corrosion on brake components due to a lack of regular heat cycles. Prospective buyers should pay close attention to the tyre condition, as the 2024 MOT specifically flagged perishing and cracking across all tyres. You must verify if a full set of replacements was fitted; if not, inspect the sidewalls for fine cracks and check the date stamps, as aged rubber loses grip and structural integrity regardless of tread depth. Additionally, the 2023 advisory for play in the nearside front track rod end should be investigated. During a test drive, listen for any clunking sounds when turning the wheel at low speeds or feel for any instability or vagueness in the steering response. Given the low annual mileage, a thorough physical inspection of the chassis and braking system is essential. Check the brake discs for heavy surface corrosion or evidence of binding calipers, which often occurs when a vehicle stands for extended periods. You should also examine the engine and gearbox area for any residual oil leaks, referencing the 2019 advisory, and verify that the 12V battery is healthy and not nearing the end of its life. Finally, ensure the service history reflects calendar-based fluid changes rather than just mileage-based intervals, as brake fluid and engine oil degrade over time regardless of the distance travelled.
