2015 Audi A6 3.0L Diesel · YF65 FVV

The most recent MOT, carried out on 31 October 2025, was passed with no recorded defects, and the preceding three annual tests (December 2024, August 2023 and April 2022) also returned clean passes. This unbroken string of defect‑free results suggests a stable maintenance pattern, with no evidence of recurring failures or deteriorating components over the last four years. While a clean MOT does not guarantee flawless condition, it does indicate that the vehicle has been kept within the statutory safety parameters and that any major wear items have either been serviced or have not yet reached the failure thresholds. At 153,354 miles on a 2015 model, the Audi A6 averages roughly 13,900 miles per year, considerably above the UK average of 8‑10 k miles for a vehicle of this age. Such a mileage level points to a relatively high‑use duty cycle, which accelerates wear on consumables such as brake pads, discs, clutch components, suspension bushings and engine bearings. The absence of any MOT‑recorded defects may simply reflect timely servicing, but the cumulative mileage still warrants a thorough inspection of wear‑prone items, especially given the potential for hidden fatigue in the chassis and drivetrain that only becomes apparent under load. A prospective buyer should give particular attention to the condition of the tyres, checking for sidewall cracking, tread depth below 3 mm, and any uneven wear patterns that could indicate mis‑aligned suspension or worn camber/caster bushes. The 12‑volt battery, now approaching a decade of service, should be load‑tested for cranking voltage and inspected for electrolyte level or swelling, as age‑related degradation can lead to intermittent starting issues. Brake discs should be examined for surface rust, scoring or glazing, and pads measured for remaining thickness; any shudder or pulsation when braking at speed would suggest disc warping or uneven pad wear. Likewise, the suspension should be probed for play in the front control arm bushings, rear coil springs and anti‑roll bar links, listening for clunks over bumps that would indicate deteriorated rubber or worn metal joints. Finally, verify that time‑based fluid changes have been observed: engine oil and filter should have been replaced at least every 10‑15 k miles, and the gearbox oil (especially if it is a DSG) typically requires service around 40‑60 k miles or every four years. Coolant, brake fluid and power‑steering fluid also have calendar limits and should be fresh to prevent corrosion and moisture ingress. A review of the service book for stamped entries, especially for major services such as timing‑belt or chain replacement (if applicable) and any recorded DPF regeneration or fault codes, will give further confidence that the high mileage has been managed responsibly. A comprehensive test‑drive, listening for abnormal noises from the engine, transmission and rear differential, and checking for any warning lights, will round out the assessment before committing to purchase.
