2018 Audi A6 2.0L Diesel · SB18 AEF

The 2018 Audi A6 in question presents a clean MOT history over the past two years, with the most recent test on 26 October 2024 at 114,525 miles showing no defects—an outcome repeated in the September 2023 and April 2022 tests at 96,244 and 80,292 miles , respectively. This consistency suggests the vehicle has been maintained to a high standard, with no recurring advisories or failures to indicate neglect or systemic issues. The absence of defects across three consecutive MOTs, particularly on critical areas like brakes, suspension, or structural integrity, implies that major components have either been well-maintained or are inherently robust for its age. However, the lack of recorded advisories could also reflect a tester’s leniency or a vehicle that has been prepped for inspection, so a buyer should verify whether any components—such as suspension bushes, brake fluid condition, or coil springs—have been recently replaced. The mileage accumulation is notably aggressive for an eight-year-old vehicle, averaging 14,316 miles per year , which is well above the UK average and suggests either commercial use, frequent long-distance driving, or a history of rapid resale. The gap between the April 2022 and September 2023 tests ( 15,952 miles in 17 months ) and the subsequent 18,281 miles in just 13 months by October 2024 further underscores this trend. Such high mileage increases wear on consumables like tyres, brake pads, and clutch components, while also accelerating fatigue in suspension elements and drivetrain seals. The fact that no defects were recorded despite this heavy usage may indicate either meticulous maintenance or a vehicle that has been driven in a way that avoids harsh conditions—though this cannot be confirmed without service records. Given the clean MOT history, a buyer should prioritise a thorough inspection of high-wear areas that may not have been scrutinised during testing. Pay particular attention to the rear suspension , as Audi A6 models of this era have been prone to coil spring sagging or binding rear calipers—issues that can go unnoticed in a basic MOT but lead to uneven tyre wear or brake drag. The brake system should be checked for fluid condition, pad thickness, and disc warping, especially given the elevated mileage. Exhaust emissions may also warrant closer inspection, as high-mileage Audis can develop leaks or catalytic converter inefficiency over time. Finally, while the MOT records show no corrosion-related failures, a full underbody check for structural rust —particularly around wheel arches, sills, and suspension mounts—is essential, as this can compromise safety without immediate visual signs.
