2018 Audi A6 2.0L Diesel · AF68 EXU

Structural integrity and braking system components present the primary mechanical risks for this vehicle, following a recent failure in February 2026 due to dangerously worn front brake pads. This latest test outcome follows a pattern of significant component degradation, most notably the February 2025 failure regarding serious corrosion on the nearside rear lower coil spring mounting. While the vehicle has secured passes since these specific defects were addressed, the recurrence of issues involving both the braking system and suspension mounting points indicates a history of mechanical wear that requires close scrutiny. The recorded mileage of 74,548 miles over approximately eight years represents a typical usage pattern of roughly 9,300 miles per year. This level of annual accumulation is consistent with standard long-distance or mixed-use driving and does not suggest the extreme high-mileage wear associated with heavy commercial use, nor does it indicate the potential for component seizure or fluid degradation often found in vehicles subjected to long periods of inactivity. The mileage progression appears steady, which generally implies a consistent level of mechanical demand on the drivetrain and consumables. A prospective buyer should focus heavily on the suspension and braking systems during a physical inspection and test drive. Given the previous failure of the nearside rear lower coil spring mounting due to corrosion, it is essential to inspect the rear subframe and all surrounding suspension linkages for any signs of advancing rust or structural weakening. On the road, listen for any dull knocks, clunks, or metallic banging when driving over uneven surfaces or speed bumps, as these could indicate that the previously addressed corrosion has affected adjacent components or that the repair was not comprehensive. Regarding the braking system, the recent failure for thin front brake pads and the advisory for a nearside rear tyre worn on the edge suggest that wheel alignment and braking component life should be verified. During a test drive, check for any steering pull under braking or uneven tyre wear across the tread surface, which could point to geometry issues. Additionally, monitor the brake pedal for any unusual vibrations, judder, or changes in bite, ensuring that the recent replacement of the front pads has resulted in consistent and responsive stopping power across all four wheels.
