2009 Audi A4 2.0L Diesel · CK59 BOF

The vehicle presents a concerning maintenance profile characterized by a trend of worsening structural and mechanical degradation. While it passed its most recent test in July 2025 at 114,569 miles, this followed a significant failure just twenty-nine days prior at 114,549 miles. The July failure revealed critical issues, including excessive corrosion on the offside front vehicle structure affecting strength, indicating that the vehicle is reaching a stage where structural integrity is a reactive rather than a preventative concern. At 17 years old, the recorded mileage of 114,569 miles represents an average of approximately 6,700 miles per year, which is consistent with low-use domestic patterns. However, the data shows a notable two-year gap between the September 2021 test at 100,164 miles and the August 2023 test at 108,922 miles. This period of relative inactivity, combined with the age of the vehicle, likely contributed to the accelerated surface corrosion and the degradation of rubber components noted in the later records. A buyer must prioritise a thorough physical inspection of the offside front chassis mounting area. The July 2025 failure flagged structural corrosion within 30cm of the inner wing, and despite the subsequent pass, this type of oxidation often progresses if not treated. The rear subframe has been noted as corroded since 2025, and while not yet seriously weakened, the recurring mention of rust requires close monitoring to ensure it does not lead to a structural failure. The vehicle also shows a history of neglect regarding wear items. Upper suspension arm bushes and coil springs have appeared in the multiple 2025 tests, while recurring inner tyre wear on both front and rear across several years suggests a persistent misalignment. The front brake pads were noted as thin in the latest 2025 record, indicating that basic consumable maintenance is performed only at the point of failure rather than on a scheduled basis.
