2015 Mercedes-Benz A-Class 1.5L Diesel · FV64 ONB

The vehicle’s most recent MOT test on 2026-03-05 confirms it remains roadworthy, having passed without defects at 110,907 miles. However, the record reveals an inconsistent pattern: two consecutive failures in March 2024 and 2025, both at nearly identical mileages (98,103 and 104,640), followed by immediate retests that passed. This suggests either a brief but critical issue resolved before the retest or a test centre error in initial assessment. The final pass in March 2026, just four months ago, indicates no ongoing major failures, but the earlier instability warrants closer scrutiny of components prone to intermittent faults. The mileage progression shows a steady average of around 10,082 miles per year, typical for a vehicle of this age. There are no prolonged gaps or abrupt spikes, though the two retests in 2024 and 2025—each separated by just one day—highlight a potential rush to compliance rather than proactive maintenance. The lack of advisories in any test suggests no recurring minor issues were documented, but the failures themselves imply a focus on high-priority systems during those retests. Given the earlier failures, a buyer should prioritise an inspection of the brake system, particularly rear calipers or binding points, as these are common causes of sudden MOT failures. The suspension—especially rear bushes and coil springs—should be checked for uneven wear or corrosion, as these components often exhibit intermittent faults. Exhaust emissions were not flagged, but a recent check of the DPF or catalytic converter would be prudent if the vehicle has diesel particulate filters. Structural integrity, particularly around wheel arches and sills, should also be assessed for corrosion, given the car’s age and typical exposure risks. The absence of advisories does not guarantee these areas are flawless, but it does indicate they were not severe enough to fail a test.
