2017 Audi A3 1.4L Petrol · KF66 DXG

The 2017 Audi A3 presents a broadly stable maintenance picture, though the most recent MOT on 26 August 2025 at 83,804 miles flagged two advisories that warrant attention. The tester noted a slight leak from the nearside rear shock absorber and recorded the offside rear tyre at the legal wear limit. Neither defect prevented a pass, but together they suggest the car is entering a phase where ageing suspension components and consumable wear are beginning to surface. The trend since 2022 shows a clean bill of health for three consecutive years, followed by these minor advisories at the latest test, indicating a gradual shift from defect-free to early-stage wear rather than any sudden mechanical deterioration. The mileage progression is consistent and well-documented. Between the failed test on 25 August 2022 at 54,389 miles and the most recent pass on 26 August 2025 at 83,804 miles, the car accumulated 29,415 miles over three years, averaging roughly 9,800 miles per year. This sits slightly above the overall lifetime average of 9,312 miles per year and points to sustained regular use rather than long periods of inactivity. No anomalous gaps or sudden jumps appear in the record, and the annual MOT pattern each August suggests a disciplined approach to compliance. The nearside rear shock absorber leak is the most mechanically significant finding. A slight leak today can progress to reduced damping performance, uneven tyre wear, and compromised handling if left unaddressed. A buyer should have the rear suspension inspected for damper condition, coil spring integrity, and the condition of top mounts and bushes. The offside rear tyre at the wear limit is a straightforward consumable issue, but it is worth checking whether the nearside rear and both front tyres show even wear, as uneven patterns can point to alignment or suspension geometry problems. Beyond the flagged items, a pre-purchase inspection should focus on the structural underside of the car. At nine years old, subframe mounting points, suspension arm bushes, and brake line condition are all areas where corrosion or fatigue can develop, particularly if the car has been used on salted roads. The brake system deserves close scrutiny given the rear tyre wear pattern; binding calipers or uneven pad wear could explain asymmetric tyre degradation. An exhaust emissions check and a visual inspection of the catalytic converter and DPF system, where fitted, would round out a thorough assessment of this otherwise well-maintained example.
