2009 Audi Q7 3.0L Diesel · CU59 BWG

A recurring pattern of component wear and fluid leakage defines the mechanical profile of this Audi Q7, with recent records showing a transition from structural and suspension concerns toward ongoing lubrication and sealing issues. While the most recent test on 26 June 2026 resulted in a pass, the history reveals a trend of deteriorating rubber components and gradual wear in the braking and suspension systems. Previous years have seen specific failures and minors related to CV boot deterioration, suspension arm ball joint dust covers, and lighting malfunctions, suggesting that while the vehicle remains roadworthy, it is subject to consistent wear on its various rubber seals and mechanical linkages. The vehicle has covered 145,762 miles over its approximately 17-year lifespan, representing an average annual accumulation of roughly 8,574 miles. This usage pattern is typical for its age and indicates a consistent level of road use rather than extreme high-mileage driving or prolonged periods of inactivity. Mechanically, this level of mileage suggests that components such as the drivetrain, suspension bushings, and braking hardware are entering a phase of life where wear and tear on consumables and seals are expected to manifest more frequently in MOT advisories. Prospective buyers should pay close attention to the reported oil leak noted in June 2024, which was specifically linked to a potential prob shaft seal. During a test drive, it is essential to monitor for any signs of fluid weeping under the vehicle or any changes in engine performance that might suggest the leak is progressing. Additionally, the 2023 record highlighted severely deteriorated CV boots on both front outer drive shafts and a worn lower suspension arm ball joint dust cover. You should listen for rhythmic clicking sounds when turning the steering wheel at low speeds, which can indicate CV joint wear, and feel for any knocking or clunking noises when driving over uneven surfaces or speed bumps, which may signal issues with the suspension bushings or ball joints. The braking system has also been a frequent subject of advisories, with historical notes on worn brake discs, thinning pads, and deteriorating brake hoses. While these issues may have been addressed since their last recording, the vehicle should be tested for any pedal judder or sponginess, which could indicate uneven disc wear or compromised hydraulic integrity. Furthermore, the 2019 advisory regarding worn front subframe mounting bushes suggests that the structural mounting points for the front suspension have been under stress; any pulling to one side during braking or steering should be investigated to ensure the subframe and its associated bushings remain stable.
