2009 Audi A5 2.7L Diesel · BA55 ABY

The Audi A5 presents a highly stable maintenance trend, demonstrating consistent mechanical reliability across its recent history. The most recent MOT test on 8 May 2025 at 142,757 miles passed without a single defect, mirroring the clean bills of health recorded in 2024, 2023, and 2021. This unbroken sequence of zero-advisory, zero-defect passes indicates a vehicle that has remained fundamentally sound, with no recurring mechanical or structural issues surfacing under scrutiny. However, with the current date in July 2026, the vehicle is now overdue for its annual assessment, meaning a fresh evaluation is required to verify its present condition. The mileage accumulation aligns closely with typical usage for a vehicle of this age, averaging roughly 8,400 miles annually. Analysing the intervals reveals a notable gap between the November 2021 test at 101,479 miles and the April 2023 test at 103,981 miles, suggesting a period of very light use or potential stationary storage over those seventeen months. Following this lull, the car covered 12,155 miles between April 2023 and April 2024, before a substantial jump of 26,621 miles occurred between April 2024 and May 2025. This recent spike in usage points to a shift toward regular, heavier driving rather than short local trips. Despite the pristine MOT record, the absence of recorded defects does not eliminate the need for a physical inspection of typical age-related wear components. A buyer should thoroughly examine the condition of the suspension bushes and coil springs, as high-mileage Audis frequently suffer from premature deterioration in these areas that might not always trigger a test failure. The brake discs and calipers require close scrutiny for corrosion or binding, particularly given the period of potential standing suggested by the 2021-2023 mileage gap. Inspecting the exhaust system for leaks and checking the structural integrity of the underbody for corrosion will confirm whether the recent high-intensity usage has inflicted any underlying stress on the drivetrain or chassis.
