2005 Audi A4 2.0L Diesel · KS54 APZ

This 2005 Audi A4 has demonstrated a stable roadworthiness trend over the past two years, with the most recent MOT test on 14 August 2024 confirming no defects at 145,578 miles. The sole failure in July 2024—just three days before passing—was unusually anomalous, as no specific faults were recorded, suggesting either a procedural oversight or a minor administrative issue rather than a mechanical recurrence. The absence of advisories or repeated failures across all tests implies that major systems like suspension, brakes, and emissions have not exhibited critical degradation. However, the 2024 failure does warrant scrutiny of whether the vehicle was driven between tests or if the test centre’s documentation was incomplete. The mileage progression of roughly 6,900 miles annually aligns with typical usage for a vehicle of this age, though the gap between the 2023 and 2022 tests—approximately 3,600 miles—suggests a period of lighter use or storage. The rapid accumulation of 578 miles between the failed and passed tests in 2024 is unusual and may indicate either a brief period of active driving or an error in the test centre’s mileage recording. No extended periods of inactivity are evident, which could have accelerated wear on components like suspension bushes or fluid-based systems. Given the clean MOT history, a buyer should prioritise an inspection of high-wear items that are not directly tested by the MOT but critical for longevity. Focus on the suspension—particularly rear bushes and coil springs—for signs of excessive play or corrosion, as these are common failure points in older Audi models. The braking system, including rear caliper binding (a frequent issue in this vehicle) and front disc thickness, should be checked for uneven wear or corrosion. Exhaust emissions, though not failed, may warrant a closer look for leaks or catalytic converter efficiency, especially if the vehicle has been driven sporadically. Structural integrity, particularly around wheel arches and sills, should be examined for corrosion, as this age group is prone to rust-related failures. Finally, verify the condition of the timing belt (if applicable) and associated water pump, as these are often overlooked but critical components.
