2012 Audi Q7 3.0L Diesel · ML12 GHB

Recurring oil leakage and suspension component wear represent the primary mechanical concerns for this Audi Q7, despite a relatively stable testing history. The most recent MOT on 08 July 2023 resulted in a pass, but it carried advisories for a front oil leak and an offside front tyre worn close to the legal limit or worn on the edge. This oil leak advisory was previously noted in February 2020, indicating a persistent issue that has not been rectified through the testing cycle. While the vehicle has maintained a consistent pass rate since 2017, the reappearance of fluid leaks and the presence of suspension play in previous years suggest a pattern of wear on seals and bushings that requires close monitoring. The vehicle has covered 149,017 miles over its approximately 14-year lifespan, averaging roughly 10,644 miles per year. This usage profile is consistent with typical long-term road use for a large SUV of this age. Such mileage levels generally imply a standard progression of wear across heavy-duty components, including the drivetrain, suspension linkages, and braking systems. Because the mileage has been accumulated steadily rather than in short, intense bursts or through long periods of inactivity, the mechanical wear is likely distributed across the vehicle's major assemblies, though it necessitates a thorough inspection of all rubber components and fluid-retaining seals. Prospective buyers should pay particular attention to the reported oil leak to determine if it is a minor seepage or a more significant failure of a gasket or seal. During a test drive, look for any evidence of oil misting on the underside of the engine or transmission, and listen for any rhythmic tapping or unusual engine noise that could indicate oil pressure issues. The 2017 advisory regarding play in the offside front inner suspension arm bush should also be investigated. On the road, this may manifest as a knocking or clunking sound when driving over uneven surfaces or bumps, or a slight wandering sensation through the steering wheel when navigating straight sections of road. The tyre advisory from the 2023 test indicates potential issues with wheel alignment or uneven tread wear. It is essential to inspect the current condition of all four tyres for similar edge wear, which could point to underlying geometry problems such as worn tie rod ends or incorrect camber settings. Additionally, given the 2020 failure regarding headlamp aim and seat adjustment mechanisms, ensure that all lighting is correctly calibrated and that the driver's seat functions smoothly without hesitation. Any signs of fluid weeping around the front suspension or steering rack should be treated as a high priority during a physical inspection.
