2020 Audi A6 2.0L Diesel · H28 RDJ

A single dangerous defect punctuates an otherwise clean record for this A6: in August 2023 the car failed its MOT because the nearside rear tyre had ply or cords exposed, a serious structural failure of the tyre carcass that rendered the car unroadworthy until rectified. The same test day also recorded a minor windscreen defect and an advisory for rear brake pads wearing thin, and the car passed on retest that same day, indicating the tyre was replaced promptly. Since then the trajectory has improved markedly, with clean passes in August 2024 and most recently on 12 September 2025 with no defects or advisories recorded whatsoever, suggesting the earlier wear items were addressed and nothing new has emerged. The recorded mileage of 58,832 miles over roughly six years equates to about 9,800 miles per year, which is entirely typical for a car of this age and type. The annual test dates show consistent year-on-year use with no gaps in the testing record and no periods where the car appears to have stood unused for extended spells. This steady, moderate accumulation is consistent with normal mixed driving rather than either heavy motorway use or prolonged storage, so wear on consumables such as tyres, brakes and suspension components should be broadly proportionate to the odometer reading. The exposed-cord tyre failure deserves attention beyond the simple fact of its rectification. Cords showing through on a single rear tyre can result from simple wear to the legal limit and beyond, but on a car of this mileage it is worth checking whether uneven rear tyre wear persists, since it can point to rear suspension geometry issues or worn bushes on this multi-link axle. On a test drive, listen for any droning or humming from the rear that could indicate unevenly worn tyre shoulders, and check the tread depth across the full width of both rear tyres for inner or outer edge wear. The 2023 advisory for rear brake pads wearing thin was not repeated in 2024 or 2025, which is consistent with the pads having been replaced, but a buyer should still verify the condition of the rear discs and pads directly, feeling for any judder through the pedal under braking and listening for scraping or squeal. The windscreen minor defect from 2023 should also be checked to confirm any chip or crack was repaired rather than left to spread, as an unnoticed chip in the driver's line of sight can become an MOT failure. Overall the recent record is clean, but a pre-purchase inspection of the rear tyres, brakes and suspension bushes would confirm that the 2023 issues have not recurred.
