2018 Audi A6 4.0L Petrol · PL67 CFO

The most recent MOT, carried out on 6 October 2025, was passed with no recorded defects, and the three preceding annual tests (2024, 2023 and 2022) also returned clean passes. This uninterrupted sequence of defect‑free results suggests a consistently stable maintenance regime and no emerging mechanical issues that have been flagged by the official DVSA inspections. The absence of advisories across four consecutive years indicates that the vehicle’s major systems – brakes, suspension, emissions and safety‑critical components – have remained within acceptable limits at the time of each test. At 52,336 mi on an eight‑year‑old 2018 Audi A6 the average annual mileage works out at roughly 6,500 mi per year, which is well below the UK average for a vehicle of this age. Such relatively low utilisation can be a positive sign for wear‑related items such as clutch plates, gearbox bearings and tyre tread, yet it also raises the possibility of prolonged periods of inactivity. Extended standing can lead to rubber perishing, battery sulphation and the development of surface rust on brake discs and suspension joints, all of which are time‑dependent rather than mileage‑dependent. Prospective buyers should give particular attention to the condition of the tyres, inspecting the tread depth and, more importantly, the sidewalls for any signs of cracking, hardening or dry‑rot that can develop even on low‑mileage tyres after several years on the shelf. The 12‑volt battery should be load‑tested, as a vehicle that has spent time idle is prone to reduced cranking power and possible electrolyte stratification. All fluid reservoirs – engine oil, coolant, brake fluid and power‑steering fluid – should be examined for colour, level and any evidence of contamination; fluids typically require replacement on a calendar basis (oil every 12‑15 months, brake fluid every two years) regardless of mileage. Finally, a thorough visual and functional check of the braking system is advisable: look for surface rust on the discs, verify that the pads have sufficient material, and listen for any squeal or shudder when applying the brakes. The suspension should be examined for worn bushings, cracked mounts or leaking dampers, especially since age‑related degradation can manifest as clunking over bumps or uneven tyre wear. Confirm that the service booklet shows regular oil changes, timing‑belt or chain service (if applicable) and that any manufacturer‑specified time‑based interventions – such as spark‑plug replacement or coolant flush – have been performed. A short test drive listening for abnormal noises, checking steering feel and confirming smooth gear shifts will round out the assessment before committing to purchase.
