2010 Audi A8 4.1L Diesel · KU60 AFO

Structural integrity and chassis modifications represent the primary mechanical concerns for this vehicle, specifically regarding the sub-frames. While the most recent test on 28 November 2025 resulted in a pass with a minor side repeater fault and a tyre advisory, the history reveals a period of significant structural instability. In 2023 and 2024, the vehicle failed due to a seriously weakened front sub-frame and an unsafe welded modification to the rear sub-frame, alongside chronic corrosion. With 157,231 recorded miles over sixteen years, the vehicle has averaged approximately 9,827 miles per year, which is typical for its age. This consistent usage suggests a steady accumulation of wear on drivetrain components and suspension linkages. The transition from clean passes between 2020 and 2022 to multiple major failures in 2023 and 2024 indicates that the vehicle reached a critical threshold of wear and corrosion during this period. Particular attention must be paid to the quality of the repairs performed on the front and rear sub-frames. Because the records explicitly mention unsafe welded modifications and serious corrosion, a physical inspection of the chassis is necessary to ensure the structural repairs meet safety standards. During a test drive, listen for metallic knocks or clunks when traversing uneven surfaces, which could indicate remaining issues with the suspension arm ball joints or bushes that were flagged in previous failures. The most recent advisory regarding the nearside front tyre wearing on the inner edge suggests a potential alignment issue or worn suspension geometry. Check for a steering pull or an off-centre steering wheel when driving in a straight line. Additionally, verify the operation of the front passenger door internal release and the integrity of the exhaust system, as these were previous major failure points that require confirmation of permanent rectification.
