2017 Audi A5 2.0L Diesel · BF67 YCW

The 2017 Audi A5 presents a broadly stable maintenance trend, with the most recent MOT test conducted on 10 October 2025 at 83,729 miles resulting in a clean pass and zero defects recorded. That outcome follows a straightforward failure on the same date, where the tester flagged an ABS warning lamp indicating an anti-lock braking system fault, along with both front wiper blades failing to clear the windscreen effectively. Both items were evidently rectified before the pass was issued later that day, suggesting the faults were addressed promptly rather than left to linger. The preceding tests in September 2024 at 81,463 miles and August 2023 at 80,967 miles also passed cleanly, with only one earlier failure in August 2023 for a mismatched tyre size on the nearside rear axle and a space-saver spare fitted. That tyre issue was a one-off and resolved at the retest. The mileage accumulation is consistent and unremarkable for a nine-year-old vehicle. Between the August 2023 test at 80,967 miles and the September 2024 test at 81,463 miles, the car covered just 496 miles over roughly thirteen months, indicating a period of very light use or possible standing. From September 2024 to October 2025, the car added 2,266 miles over approximately thirteen months, which remains well below the typical annual average of around 9,303 miles for its age. The overall pattern suggests this A5 has been used sparingly in recent years, which generally favours reduced wear on consumables, suspension components, and drivetrain parts, though prolonged periods of inactivity can introduce its own concerns such as brake surface corrosion, tyre flat-spotting, and stale fuel or coolant degradation. A buyer inspecting this vehicle in person should pay particular attention to the braking system, given the ABS fault that triggered the October 2025 failure. The ABS warning lamp indicates a fault within the anti-lock braking system, which could stem from a wheel speed sensor, a faulty ABS pump or control module, or wiring damage. Even though the fault was cleared for the retest, a diagnostic scan for stored ABS fault codes would confirm whether the underlying cause was properly repaired or simply reset. The condition of the brake discs and pads should also be physically inspected for uneven wear or surface corrosion, particularly if the car has been sitting for extended periods during its recent low-mileage phase. Tyre condition and matching across each axle merit a close look as well, given the August 2023 failure for a mismatched nearside rear tyre and a space-saver fitment, which suggests at least one previous owner did not maintain correct tyre specification. Beyond these flagged items, a thorough underbody inspection for corrosion, especially around suspension mounting points, subframes, and inner wing arches, is advisable on any Audi A5 of this age, as is checking the condition of suspension bushes, coil springs, and exhaust components for deterioration consistent with the vehicle's age.
