2012 Audi A8 3.0L Diesel · OU12 XBG

The vehicle remains roadworthy, but the maintenance history indicates a trend of developing mechanical wear and deferred minor repairs. The most recent test in July 2025 at 136,487 miles identified a front oil leak and wear on both nearside and offside front upper suspension arm bushes. While the vehicle passed, these advisories suggest the suspension geometry is reaching the end of its functional life and the engine seals require monitoring to prevent the leak from becoming a significant failure. The mileage data appears highly inconsistent, suggesting either odometer discrepancies or significant usage fluctuations. Between July 2022 and July 2024, the vehicle covered 91,336 miles in just two years, which is far above average for a luxury saloon of this age. Conversely, the record shows a drop to 136,487 miles in 2025 after having 168,730 miles in 2024, which is a chronological impossibility. Assuming the current figure of 136,487 miles is the accurate baseline, the high-intensity usage period likely placed considerable strain on the complex drivetrain and air suspension components. A buyer must prioritise a physical inspection of the front suspension system due to the recurring bush wear noted in 2025. The previous failure in 2023 for inner tyre tread depth, combined with edge wear in 2024, indicates persistent alignment issues or worn components that remain unresolved. The front oil leak identified in the latest test should be traced to determine if it is a simple cover gasket or a more costly seal failure. Additionally, the nearside windscreen should be checked for spreading cracks that could compromise structural integrity under pressure.
