2017 Audi A4 2.0L Diesel · JC55 ATC

The 2017 Audi A4’s most recent MOT history demonstrates a stable but unusual pattern, with a single failure in July 2025—despite no recorded defects—followed by an immediate pass the next day at identical mileage. This suggests either a minor administrative oversight or a test centre error, as no mechanical issues were logged. The preceding tests, spanning from February 2023 to July 2024, all passed without fail, indicating no consistent underlying problems during those intervals. The lack of advisories or recurring faults implies the vehicle has not suffered from persistent issues like suspension deterioration, excessive brake wear, or structural corrosion. However, the abrupt failure and re-test warrant scrutiny of whether the vehicle was driven between those dates, as the mileage remained unchanged. Mileage progression reveals a consistent annual average of approximately 9,350 miles, which aligns with typical usage for a vehicle of this age. The gap between the 2023 February and August tests—covering 3,436 miles in just six weeks—stands out as unusually rapid, potentially indicating either intensive use or a period of frequent short trips. Conversely, the 11-month span between the 2024 and 2025 tests, with only 10,820 miles accumulated, suggests a quieter period. While this pattern does not inherently signal neglect, it does imply the vehicle was not stored long-term, which could affect components like battery health or fluid degradation. Given the clean MOT record, a buyer should prioritise an in-person inspection of high-wear items that are not directly tested under MOT standards. Focus on the suspension, particularly the condition of rear bushes and coil springs, as these often degrade incrementally without immediate failure. The brakes, while never flagged, should be examined for uneven wear or binding calipers, especially if the vehicle was driven through heavy traffic during the rapid mileage period. Structural integrity is less of a concern here, but a thorough check for corrosion around wheel arches, sills, and the subframe is advisable, particularly given the vehicle’s age. Finally, verify the integrity of the exhaust system for leaks or damage, as emissions-related failures are not always captured in MOT reports.
