2018 Audi A3 1.5L Petrol · RO51 ACO

The 2018 Audi A3 shows a stable roadworthiness trend over the past three MOT cycles, with the most recent test on 14 April 2025 at 68,431 miles passing without any defects. The absence of advisories or failings in the last two tests suggests the vehicle has remained within regulatory compliance for major systems, though the repeated failures at identical mileages in 2023 and 2024 warrant closer scrutiny. The 2025 test’s clean pass indicates no unresolved issues from prior cycles, but the pattern of two consecutive failures at the same mileage—53,309 and 61,429—implies either a recurring minor fault or administrative oversight rather than a critical mechanical failure. The recorded mileage of 68,431 miles over eight years aligns with typical usage for this age, averaging around 8,554 miles annually. There are no significant gaps or abrupt spikes in mileage between tests, though the near-identical mileages for the 2024 and 2023 failures (53,309 and 61,429) suggest either a test date mix-up or a fault that resurfaced at predictable intervals. The lack of intermediate MOTs or service records means there’s no evidence of proactive maintenance between tests, which could mask underlying wear in suspension components, brake systems, or drivetrain elements. Given the repeated failures at identical mileages, a buyer should prioritise an independent inspection of the brake system, particularly the rear calipers and pads, as binding brakes were likely the cause. The suspension—including coil springs, bushes, and dampers—should be checked for uneven wear or corrosion, especially if the vehicle has experienced wet or salted roads. Structural integrity of the chassis and subframe should also be assessed for signs of rust or deformation, particularly around wheel arches and underbody panels. The absence of defects in the last two tests does not guarantee these areas are sound, so visual and functional checks are essential.
