2017 Audi A4 1.4L Petrol · AV67 OGA

The most recent MOT tests on this 2017 Audi A4, conducted just over a year ago on 28 May 2025, reveal a concerning pattern of repeated failures despite identical mileage readings. The vehicle passed one test at 59,499 miles before failing the subsequent one on the same day, a scenario that strongly suggests either a test centre error or a critical component that was just at the threshold of failure. Given the absence of recorded defects in any of the previous tests—including the 2024 and 2023 cycles—this abrupt failure indicates a sudden deterioration in a major system, likely brakes, suspension, or emissions. The lack of advisories or partial passes in prior records implies that no prior owner addressed a developing issue before it reached a critical state. The recorded mileage progression of 6,611 miles per year over the past nine years aligns with typical usage for this vehicle’s age, though the abrupt jump from 54,103 miles in June 2024 to 59,499 miles by May 2025—an increase of 5,396 miles in just over a year—suggests either a period of heavier use or a delay in MOT testing. The identical mileage readings for both the 2025 pass and fail further imply the odometer was not tampered with, but the sudden failure at the same mileage points to a component nearing its serviceable limit. There are no gaps in testing that would indicate neglect, though the repeated failure at the same mileage is unusual and warrants scrutiny. Given the lack of recorded defects in prior MOTs, the most likely candidates for the 2025 failure are the braking system or suspension components, as these are common failure points at this mileage. A buyer should prioritise a thorough inspection of the rear brake calipers and discs—binding brakes were a frequent cause of MOT failures in this class—alongside the suspension bushes and coil springs for excessive wear or corrosion. The absence of advisories in earlier tests also raises the possibility of a minor but critical failure in the exhaust emissions system, such as a failing catalytic converter or oxygen sensor, which could explain the sudden failure without prior warning. Structural integrity should also be checked, particularly around the wheel arches and sills, where corrosion can compromise safety without immediate MOT failure. Given the vehicle’s age and the abrupt failure pattern, independent verification of the brakes and suspension is essential.
