2015 Audi A6 2.0L Diesel · G13 GSD

The 2015 Audi A6 presents a clean MOT history over the past three years, with the most recent test on 17 October 2025 at 156,433 miles passing without defects—a trend that has remained stable since 2022 , when the last recorded test also showed no issues. The absence of advisories or failures in this period suggests the vehicle has been well maintained in critical areas, including brakes, suspension, and structural integrity. No recurring faults indicate neglect, though the duplicate 17 October 2023 entry (one pass, one fail) is unusual and may warrant clarification from the seller—whether it was a test error or a minor oversight resolved before retesting. Mileage accumulation has been aggressive, with 14,221 miles per year over the past decade, which is high for a vehicle of this age. The gap between 136,297 miles (2022) and 156,433 miles (2025) —a 20,136-mile jump in three years —implies consistent, heavy use, likely accelerating wear on consumables like tyres, brake pads, and suspension bushes. The lack of MOT failures despite this suggests either meticulous servicing or a history of replacing worn components preemptively. However, a buyer should verify if major services (e.g., brake fluid changes, coil spring inspections) align with Audi’s recommended intervals, as high mileage increases the risk of hidden fatigue in components like ball joints or wheel bearings. Given the clean MOT history, priority inspections should focus on brake system health , particularly the rear calipers and discs, which are prone to binding or corrosion over time. The suspension—including control arm bushes, coil springs, and track rod ends —should be checked for excessive wear or leaks, as high mileage can lead to premature failure. Exhaust emissions may also warrant a closer look, given the vehicle’s age, though the MOT records show no prior concerns. Structural corrosion, especially around wheel arches and sills, should be examined, as Audi’s aluminium-intensive construction can mask rust until it becomes critical. Finally, the servicing history —if available—should confirm whether oil changes, filter replacements, and fluid top-ups have been adhered to, as these are critical to preventing long-term engine and drivetrain issues.
