2016 Audi Q3 2.0L Diesel · LS66 XAW

The vehicle remains roadworthy, though the maintenance trend shows a transition from pristine records to emerging degradation. While the car passed four consecutive tests between 2021 and 2024 without defects, the recent inspection on 25 October 2025 at 66,364 miles identified corrosion on both the nearside and offside rear suspension arms. Although these were not classified as seriously weakened, they mark the onset of structural oxidation that was absent in the previous four years. The mileage pattern is remarkably consistent with a low-use profile, averaging approximately 6,600 miles per annum. Between the October 2021 test at 49,700 miles and the October 2025 test at 66,364 miles, the vehicle covered 16,664 miles. This steady rate of accumulation suggests the car has not been subjected to high-stress environments, though the low mileage often accelerates the degradation of rubber components and metal brackets due to inactivity rather than wear. A buyer should prioritise a physical inspection of the rear suspension assembly to assess the depth of the corrosion on the arms. Since the tester flagged rust on both sides simultaneously, it is necessary to determine if this is surface-level or if structural integrity is beginning to fail. Attention should also be paid to the suspension bushes and brake lines, as low-mileage vehicles of this age often suffer from perished rubber components that become brittle over time despite the low driving distance.
