2015 Audi A6 2.0L Diesel · PB13 MDB

A pattern of front-corner suspension, brake hose, and tyre-related advisories defines the mechanical history of this Audi A6, with the most recent test on 2026-05-08 returning a pass alongside an advisory for feathering and damage to the nearside rear tyre. Across seven recorded tests between 2019 and 2026, the vehicle has passed on every occasion except for a single failure in May 2021, which was notable for an unusual cause: all four road wheel fixings were recorded as missing on the nearside and offside front and rear wheels. Aside from that event, the trend across 2021, 2022, 2023, 2024, and 2025 was broadly stable, with the 2024 and 2025 tests both completely clear of advisories. The 2022 test, however, stands out as the most defect-laden, flagging light oil misting on both rear shock absorbers, a broken sun visor clip, smearing wiper blades, and a nearside front tyre close to the legal limit with edge cracking. The subsequent clean years suggest that several of those items were rectified, though the recurrence of tyre and brake-related advisories over the seven-year window indicates that these remain areas of recurring wear. With 142,737 miles recorded over approximately eleven years, this A6 averages around 12,976 miles per year, which sits at the higher end of typical usage for a vehicle of this age and points to substantial real-world accumulation on consumable and drivetrain components. There is a notable two-year gap between the May 2021 test and the May 2019 test, which could reflect a period off the road or simply an absence of recorded MOT data during that interval. The annual mileage implied by the consistent year-on-year testing from 2021 onwards, combined with the high overall figure, suggests that braking components, suspension bushes, and tyres have been subjected to considerably more wear than would be expected on a lower-mileage equivalent. The earlier advisory for thinning front brake pads in 2019, paired with later advisories on brake hoses, shock absorbers, and tyres, is consistent with the demands placed on a high-mileage executive saloon of this vintage. Given the recorded advisories, a prospective buyer should pay particular attention to the front suspension and braking system during any inspection. The 2023 advisory for a slightly deteriorated offside front brake hose warrants a close visual check of all four flexible brake lines for cracking, swelling under pressure, or weeping, and the pedal should feel firm without any sponginess or excessive travel on a test drive. The 2022 advisories for oil misting on both rear shock absorbers mean the offside and nearside rear dampers should be inspected for fresh oil residue on the body or piston rod, and any clonking, excessive bounce, or instability over undulating roads during the test drive would suggest the dampers have deteriorated further since that test. The 2026 advisory for feathering on the nearside rear tyre, combined with the earlier nearside front tyre edge wear, also indicates that a wheel alignment check is advisable, as uneven shoulder wear can point to worn suspension bushes or tired drop links; any knocking from the front end over bumps, vague steering, or uneven tyre wear across the axle should be investigated promptly. Finally, the structural and wheel-related history deserves specific attention. The 2021 failure caused by all four road wheel fixings being missing is unusual and points to an incident in which the wheels were either removed and not refitted correctly, or fasteners were lost; on inspection, the wheel bolts should be verified as the correct type for the vehicle, fully torqued, and free from damaged threads or rounded heads, and a check of the wheel bearing play on both sides is sensible given the mileage. The high annual mileage and the age of the vehicle also make it prudent to inspect the underbody, subframe mounting points, and suspension arms for corrosion, as these areas commonly suffer on high-mileage Audis of this generation. A thorough test drive should include firm brake applications from higher speed to confirm straight-line stability and the absence of pedal judder, together with low-speed manoeuvring to detect any clonking from the front anti-roll bar bushes or drop links, both of which are known wear items on this platform and would be consistent with the pattern observed in the MOT record.
