2017 Audi A5 2.0L Diesel · H24 BAS

The most recent MOT, carried out on 31 October 2025, was passed but recorded three advisories: the off‑side front and rear tyres were close to the legal tread limit and the near‑side front lower suspension arm pin or bush showed wear. Over the last six years the vehicle has moved from a clean record in 2020 to a serious rear coil‑spring mounting failure in 2022, a dangerous tyre tread deficiency in 2023 and a series of tyre‑wear advisories thereafter. The pattern shows that major structural faults have been addressed, yet tyre and suspension wear are recurring, indicating a maintenance trend that is currently stable but still requires vigilant attention to wear items. At 146,298 mi the 2017 Audi A5 averages roughly 16 250 mi per annum, well above the typical 8‑10 000 mi for a vehicle of this class. Such a high annual mileage accelerates wear on the engine’s timing chain, oil pump and turbocharger, while also placing additional load on the suspension bushings, rear coil‑spring mounts and brake components. The mileage suggests the car has been driven regularly rather than stored, which is favourable for mechanical health but also means consumables are likely approaching the end of their service lives. A prospective buyer should give the tyres a thorough visual and tactile inspection. Verify that the tread depth on all four wheels exceeds 1.6 mm, look for sidewall cracking or perishing that can arise from age even if tread appears adequate, and check for any embedded objects such as the previously noted nail. While on the road, listen for a hollow or clunking noise when passing bumps, which may indicate the near‑side front lower arm bush is nearing the limit of its serviceable wear, and feel for any steering wander or vibration that could point to deteriorated rear coil‑spring mounts or misaligned suspension geometry. The brake discs, previously flagged as pitted, should be examined for deep scoring or uneven wear; a pulsating pedal or shudder when applying the brakes would confirm the need for resurfacing or replacement. Given the vehicle’s age and mileage, the buyer should also confirm the condition of time‑sensitive items. Test the 12‑volt battery for cranking voltage and check for any signs of acid leakage; a battery older than four years often loses capacity under high‑load driving. Inspect all fluid reservoirs – engine oil, coolant, brake fluid and gearbox oil – for correct levels, colour and any particulate contamination, and ask for evidence of interval changes in the service book. Look for corrosion on the floor pan, wheel arches and under‑body panels, especially around the rear suspension mounting points that suffered a major failure in 2022. Finally, ensure the service history documents regular oil changes, timing‑chain or belt inspections (if applicable), and any corrective work undertaken after the MOT failures, as these records will be essential to gauge the long‑term reliability of this high‑mileage executive coupe.
