2016 Audi A4 S Line TDI 2.0L Heavy oil · MIW 10

The most recent DVSA roadworthiness test for this 2016 Audi A4 S Line TDI was conducted on 13 September 2025, and the vehicle passed with no defects or advisories recorded against it. Looking back across the available five-year MOT history, the car has achieved an unbroken run of clean passes at every annual test from 2021 through to 2025, with no advisory items logged at any stage. This pattern is a strong indicator that the vehicle has been conscientiously maintained, and the absence of recurring wear-related advisories on components such as suspension bushes, coil springs, brake discs, or underbody corrosion suggests that underlying structural and mechanical condition remains sound. The consistency of the test results demonstrates a stable maintenance trend rather than any deterioration. With 110,544 miles recorded over a ten-year life, this A4 is averaging approximately 11,054 miles per year, which sits squarely within typical usage parameters for a vehicle of this age and class. There are no extended gaps between MOT tests that would suggest prolonged standing, nor is there any evidence of unusually rapid mileage accumulation that would point to fleet or high-intensity commercial use. This level of annual mileage is generally favourable for a diesel-powered executive saloon, as it implies regular fluid circulation, consistent warm-up cycles for the engine and turbocharger, and steady use of consumables such as brakes, tyres, and clutch components. However, buyers should still treat the odometer reading as an indication of cumulative wear across two-axle driveline and chassis components, particularly given that the vehicle is now entering its second decade of service. Given the clean MOT record, physical inspection should focus on age-related degradation that an annual roadworthiness test does not always fully capture. Tyres should be examined closely for sidewall perishing and cracking caused by ten years of UV exposure and ozone attack, even if the tread depth remains legal, as aged rubber can lose grip and integrity before it wears out. The 12V battery is now well beyond its typical service life and should be load tested or replaced preventatively, particularly as a weak battery can cause electrical gremlins and starting issues in the diesel powertrain. Brake discs, especially on a vehicle that may have spent time standing between journeys, are susceptible to corrosion and surface pitting; on a test drive, listen for any juddering under braking and check for binding calipers that can cause uneven pad wear or pull to one side. Fluid servicing is another critical area for a ten-year-old diesel of this mileage. Diesel fuel systems are sensitive to water contamination and particulate build-up, so it is worth confirming that the fuel filter has been replaced at the recommended intervals and that the injectors have been kept clean. Engine oil, coolant, brake fluid, and automatic or dual-clutch transmission fluid all degrade on a calendar basis as well as through use, so full service history evidence in the form of stamped service book entries or digital records should be requested and verified. On a road test, pay particular attention to any hesitation, misfire, or excessive smoke from the exhaust, unusual turbo whistle or boost irregularities, and any clunks or knocking from the suspension over speed humps, all of which would warrant further specialist inspection before purchase.
