2020 Audi A4 S Line BLK ED 35 Tfsi Mhev 2.0L Petrol · YS70 UMV

Tyre health dominates the mechanical narrative of this 2020 Audi A4 S‑Line – the MOT record shows a succession of serious tyre defects, from a dangerous rear‑tyre lump and exposed ply in 2025 to a front‑tyre cut that breached the ply requirement the same day the car was retested in May 2026. The most recent MOT on 25 May 2026 recorded a pass but retained advisories for a front‑tyre cut that stopped short of the ply and noted slight damage on both rear tyres, while the brake discs and inner pads were flagged as worn but still within the legal limit. The pattern indicates that tyre condition has been a recurring weak point, with brake wear emerging as a secondary, though less urgent, concern. At 38,147 mi after roughly six years of age the vehicle averages about 6,300 mi per annum, a mileage rate that sits comfortably within normal UK usage for a premium saloon. The MOT history shows no long gaps between tests, suggesting the car has been regularly inspected and any emerging faults have been recorded promptly. The mileage figure, combined with the relatively modest annual accumulation, means that wear on consumables such as brake pads, discs and tyres should be proportionate to use, but the repeated tyre issues imply that the tyres may have been subjected to harsher conditions or have suffered from uneven wear patterns that are not purely mileage‑driven. A prospective buyer should give the tyre set a thorough visual and tactile inspection. Look for any cuts that reach the cord layer, sidewall bulges, or cracking on the tread of all four tyres; feel for uneven wear that could point to alignment or suspension problems. During a test drive, listen for a thumping or vibration that intensifies over bumps, which would corroborate a rear‑tyre lump or a compromised sidewall. Verify that the steering remains straight and that there is no pull to one side, as this could indicate worn front suspension arm bushes – the MOT advisories from 2025 flagged both nearside and offside front arm pins as showing wear, albeit not yet causing excessive movement. Brake performance warrants close attention. Although the discs and inner pads were only advisory items at the latest test, they were already noted as worn in 2026, suggesting they are approaching the end of their service life. Check disc thickness with a micrometer or have a workshop confirm it meets the minimum specification, and feel the pedal for any pulsation or increased travel that could signal uneven disc wear. Finally, confirm that the parking brake holds firmly on a hill; the 2025 failure for parking‑brake efficiency indicates a component that may have been repaired but could re‑fail if the underlying mechanism was not fully restored. Addressing these specific items before purchase will give a clearer picture of the car’s roadworthiness and any imminent maintenance costs.
