2017 Audi A6 2.0L Diesel · CV67 YHA

The Audi A6 in question presents a clean MOT history over the past four tests, with the most recent September 2025 inspection at 170,532 miles showing no defects—an outcome that suggests the vehicle has maintained stable roadworthiness under regular testing conditions. The absence of advisories or failures across all four records indicates no recurring mechanical issues, suspension wear, or structural concerns were identified by the tester. This consistency implies the car has either been well-maintained by its previous owner or, if neglected, has thus far avoided the common failure points that plague many high-mileage Audis, such as brake binding, suspension bush deterioration, or exhaust emissions drift. That said, the lack of advisories does not preclude hidden wear; a buyer should treat this as a baseline rather than an exhaustive mechanical clearance. The mileage accumulation is notably aggressive for a nine-year-old vehicle, averaging around 18,948 miles per year—a figure that sits well above the UK’s average for its age group. The jump from 95,444 miles in August 2021 to 124,683 miles in September 2022 (a 29,239-mile increase in just over a year) suggests either intensive use or a period of high annual mileage, which would accelerate wear on consumables like tyres, brake pads, and clutch components. The most recent 16,349-mile gap between September 2024 and September 2025 aligns more closely with typical annual mileage, but the cumulative total remains high. This pattern raises the likelihood of elevated wear on drivetrain elements, such as the dual-mass flywheel or timing belt, particularly if servicing intervals were extended. Given the clean MOT history, a prospective buyer should prioritise a thorough pre-purchase inspection focusing on components not routinely checked during standard MOT tests. The suspension—specifically the coil springs, anti-roll bars, and bushings—should be scrutinised for fatigue cracks or excessive play, as high mileage increases the risk of silent failure. Brake system integrity is critical; while the MOT records show no issues, binding calipers, uneven pad wear, or corroded brake lines could have been overlooked. The exhaust system, including the catalytic converter and DPF (if fitted), warrants inspection for blockages or leaks, as emissions compliance was not flagged but could still be compromised. Structural corrosion, particularly around wheel arches, sills, and suspension mounts, should be checked for early signs of rust penetration, which is more likely in a high-mileage vehicle with variable usage patterns. Finally, fluid levels—brake, coolant, and differential oils—should be verified, as neglect in these areas often precedes catastrophic failure in Audis of this age.
