2016 Audi A5 S Line TDI Quattro 2.0L Heavy oil · OW16 CFM

The most recent MOT on 9 July 2026 recorded a full pass with no advisory or failure items, and the preceding five tests dating back to November 2020 also returned clean passes. This uninterrupted record of successful examinations indicates a stable maintenance pattern, with no evidence of deteriorating components or recurring faults emerging during the statutory checks. The absence of advisories suggests that any routine servicing required by the manufacturer has been kept up to date, or at least that any deficiencies have not yet reached the MOT threshold. At ten years old the Audi A5 S Line TDI Quattro has logged 86 367 miles, which works out to an average of roughly 8 600 miles per annum. That figure sits comfortably within the normal UK usage envelope for a premium executive saloon and does not point to any periods of extreme short‑term mileage spikes. The relatively moderate annual run‑rate reduces the likelihood of accelerated wear on high‑stress items such as the clutch, DSG gearbox and the quattro front‑rear differentials, but it does mean the vehicle has been in service long enough for age‑related degradation of rubber and fluid media to become a factor. For a prospective buyer the principal checks should focus on time‑based wear rather than mileage‑driven failure. Inspect the tyre sidewalls for cracking, dry rot or age‑related hardening; the tyre manufacture date should be no more than six years old, irrespective of tread depth. Examine the 12‑volt battery terminals for corrosion and have the battery load‑tested, as a ten‑year‑old unit may be approaching the end of its service life. Verify that the engine oil, coolant, brake fluid and DSG (dual‑clutch) transmission fluid have been changed in accordance with Audi’s service schedule – the timing belt on the 2.0 TDI typically requires replacement at 60 000 miles or six years, so confirmation of that job is essential. Look for any signs of oil or coolant leaks around the oil pan, valve cover gaskets and the front‑rear differential seals, and check that the exhaust system is free of rust or perforations that could affect emissions compliance. During a test drive listen for any clunking or knocking from the suspension bushings, control arm pivots and the quattro centre differential, and feel for any vibration or shudder when applying the brakes, which could indicate warped discs or sticking calipers after long periods of inactivity. Observe the steering response for play or a loose feel that might betray worn tie‑rod ends or a deteriorating rack. Finally, confirm that the service book contains stamps for the major intervals, especially the timing‑belt change and DSG fluid service, as these are the most cost‑intensive items that, if overdue, will impact both reliability and resale value.
