2015 Mercedes-Benz A-Class 2.1L Diesel · SW04 TTW

The most recent MOT test on July 25, 2025, at 112,626 miles confirms the vehicle remains roadworthy under current UK standards, though the history reveals a critical suspension failure in August 2023 that was only rectified after a second attempt. The near-identical mileage at both the failure (101,352 miles) and subsequent retest (101,369 miles) suggests the rear coil springs were replaced promptly, but the recurrence of brake pad wear in the same cycle (August 2023) indicates a pattern of deferred maintenance. The absence of defects in the last two tests (2024 and 2025) suggests the vehicle has been kept in stable condition since the suspension was addressed, though the 2023 failure remains a red flag for structural integrity. The mileage progression shows a consistent annual average of around 10,200 miles, which is typical for a vehicle of this age and class. There are no extended gaps between tests that might imply neglect, nor any sudden spikes that would suggest aggressive driving. The 2022 to 2023 interval (93,144 to 101,352 miles) aligns with the expected 12-month cycle, though the failure in August 2023—just three days before the retest—highlights a period where the vehicle was likely driven with compromised suspension. The most recent test in July 2025, just under a year after the last, confirms the vehicle has been maintained within the legal window, but the 2023 incident warrants scrutiny. A buyer should prioritise an immediate inspection of the rear suspension components, particularly the coil springs and associated mounting points, to confirm the 2023 repairs were permanent and that no corrosion or fatigue has developed since. The front brake pads were noted as wearing thin in August 2023, so verifying their current thickness and checking for uneven wear—potentially caused by binding calipers or misaligned wheels—is essential. Given the fractured springs were a major failure, the structural integrity of the rear subframe and body mounts should also be examined for signs of stress or misalignment. Finally, the absence of advisories in recent tests does not guarantee future reliability, so a thorough check of fluid levels (brakes, power steering, coolant) and wear items (tyres, wiper blades) is advisable to ensure no deferred maintenance has accumulated.
