2017 Audi A5 3.0L Petrol · DX17 MYF

The 2026-06-18 verdict establishes that the vehicle is roadworthy, but the maintenance history indicates a clear deterioration trend rather than stability. The most recent test on 2025-11-07 passed at 63,175 miles, yet this was preceded by three failed tests in 2023, 2022, and 2024, where the engine exhaust carbon monoxide emissions exceeded manufacturer and default limits. This sequence of failures suggests that basic upkeep was skipped or neglected during the 2023–2024 period, leading to a progressive loss of mechanical integrity over the last two years. The mileage pattern reveals a significant gap in data, with the 2024-10-23 test at 57,356 miles being the only completed record before the 2023-09-16 failure. This lack of a full 2023-09-05 test at 54,111 miles is notable as it falls within the typical 7,000-mile annual wear zone, suggesting the vehicle may have been driven at a higher frequency or for longer durations than expected during that month. While the 2025-11-07 test at 63,175 miles is the only fully documented test, the cumulative wear from the three prior failures points to a structural risk that is not currently resolved. Consequently, the buyer must inspect the vehicle personally for binding rear brakes, suspension bushings, and exhaust emissions, as the history indicates a pattern of consumable wear and potential structural issues that require immediate professional assessment.
