2015 Audi A6 3.0L Diesel · DA65 ADV

The 2015 Audi A6 remains roadworthy with a clean pass at the October 2025 test (17,461 miles), though the maintenance trend is worsening on tyre condition. The tester flagged nearside and offside front tyres worn bold on the inner edge and a cracking nearside rear tyre, all dated 2015 units. These faults build on identical inner-edge front wear noted at the October 2024 test (13,180 miles), showing a recurring pattern of neglected rubber and possible alignment neglect rather than a one-off. Recorded mileage is exceptionally low for an eleven-year-old car, averaging roughly 1,587 miles per year. The history shows the car stood almost unused between March 2021 (4,627 miles) and May 2023 (5,984 miles), then gained 7,196 miles in the year to October 2024 and a further 4,281 by October 2025. Such low, sporadic use with long idle periods explains the original 2015 tyres still fitted in 2025 and raises the risk of perished rubber and seized suspension components from standing. A buyer should inspect all four tyres in person and replace the 2015 set regardless of tread, given the cracking and ten-year age. The repeated inner-edge front wear points to worn suspension bushes or incorrect tracking, so a four-wheel alignment and front arm inspection is warranted. Check brake calipers and discs for binding or corrosion after the long storage, and examine subframes and sills for structural rust where moisture trapped during idle periods.
