2010 Mercedes-Benz ML 3.5L Diesel · B6 MWG

The most recent MOT history for this 2010 Mercedes-Benz ML reveals a concerning pattern of instability in the final months of 2025, despite otherwise consistent pass rates. The vehicle failed on 2025-04-23 at 177,964 miles before narrowly passing the subsequent test on 2025-04-24—both at identical mileage—with no recorded defects or advisories. This abrupt reversal suggests either a last-minute correction of an undocumented issue or a procedural anomaly, though the absence of specific fault codes leaves the cause speculative. Earlier tests in 2024 and 2023 show no failures or advisories, indicating a stable roadworthiness trend for the preceding three years. However, the repeated failure in April 2023—paired with a simultaneous pass at the same mileage—mirrors the 2025 pattern, raising questions about whether critical components were overlooked or temporarily bypassed during inspection. The recorded mileage progression of approximately 11,123 miles annually aligns with typical usage for a vehicle of this age, though the lack of intermediate tests between 2023 and 2024 creates a notable gap. The jump from 156,798 miles in April 2023 to 167,721 miles in April 2024 represents roughly 10,923 miles in a single year, which, while not extreme, suggests the vehicle was actively driven rather than stored. The identical mileage at both the failed and passed tests in April 2023 and 2025 implies either a rapid correction of a minor issue or potential mileage manipulation, though the latter cannot be confirmed without further evidence. The overall pattern does not indicate extreme neglect, but the irregularities warrant scrutiny of maintenance records beyond the MOT history. Given the lack of specific defect codes in the MOT records, a buyer should prioritise an independent inspection of high-wear components that often evade standard testing. The repeated failures at identical mileages in 2023 and 2025 may hint at recurring issues with suspension integrity, particularly the rear bushes or coil springs, which are prone to gradual degradation in high-mileage Mercedes-Benz models. Binding brakes or worn brake discs—common in vehicles with aggressive braking habits—could also explain the failures, though the absence of advisories suggests these may have been addressed between tests. Structural corrosion, particularly around the wheel arches, subframe, or sills, should be examined closely, as this is a critical failure point for vehicles of this age and mileage. Additionally, the exhaust system and emissions controls, which are frequently overlooked in MOT passes, may require verification to ensure compliance with current regulations.
