2015 Mercedes-Benz A-Class 2.1L Diesel · LA15 AFJ

The most recent MOT test on August 8, 2025, confirms this 2015 Mercedes-Benz A-Class remains roadworthy at 91,634 miles, with no defects or advisories recorded. The absence of failures or repeated issues over the past three consecutive tests suggests the vehicle has been maintained consistently within legal limits, though the single failed test in August 2024—just eight miles before passing—indicates a narrow margin for error. No structural or safety-critical components were flagged in any of the five recorded tests, which is notable given the vehicle’s age and mileage. That said, the lack of advisories or minor faults in recent years could imply either diligent servicing or deferred maintenance on wear items. The mileage progression shows a steady accumulation of approximately 6,900 miles annually, which aligns with typical usage for a vehicle of this age. There are no abrupt jumps or prolonged periods of inactivity between tests, though the gap between the 2022 and 2023 tests (8,158 miles in 12 months) is slightly higher than the average. The repeated August testing dates suggest the vehicle was likely kept within the 12-month MOT cycle, though the 2024 failure—despite minimal mileage difference—may warrant scrutiny of whether the tester focused on specific high-wear areas. Given the clean MOT history, an in-person inspection should prioritise the suspension system, particularly the rear coil springs and bushes, as these are common failure points in this model at this mileage. The brakes, though never failed, should be checked for uneven wear or binding calipers, especially if the vehicle has been driven hard or exposed to heavy loads. Tyre condition remains critical; failing twice on tread depth in the past would be expected, so verify current tread depth and uniformity. Finally, examine the underbody for corrosion around the sills, wheel arches, and exhaust system, as this is a frequent issue in A-Class models of this vintage. The absence of advisories does not preclude these areas from requiring attention.
