2018 Audi A6 2.0L Diesel · DF18 ABK

The vehicle maintains a passing roadworthiness status following its most recent test on 15 December 2025. However, the maintenance trend shows a shift from recurring consumable wear to structural-related concerns. While the December 2024 test recorded no defects, the 2025 advisory identifies corrosion on the rear sub-frame. This indicates that the structural integrity is beginning to show age, which requires continued monitoring to ensure it does not progress toward a failure. At 123,631 miles over eight years, this Audi A6 has covered an average of 15,454 miles per year. This high usage profile typically places significant stress on heavy-duty suspension components and drivetrain elements. The record shows consistent testing intervals with annual entries in 2022, 2023, 2024, and 2025. The frequency of tests suggests the vehicle is used regularly, but the high mileage correlates with the specific wear patterns seen in the hardware throughout the history. A physical inspection must prioritize the front suspension geometry, as the April and December 2023 tests flagged worn bushes on both the offside and nearside front lower suspension arms. Although these did not result in failure at the time, they indicate a degradation of rubber components common at high mileage. The buyer should also verify the extent of the rear sub-frame corrosion noted in the 2025 advisory to determine if it is merely surface pitting or deeper structural thinning. Tyre maintenance also shows a pattern of reactive replacement, with multiple advisories in 2022 and 2023 noting tyres reaching the legal tread depth limit or showing uneven wear. This suggests that previous owners waited until components were near failure before addressing them. The deteriorated rear registration plate noted in 2025 is a minor cosmetic defect, but the primary focus should remain on the sub-frame and the front suspension control arm bushings. Buying score: 58 Risk level: Medium.
