2015 Mercedes-Benz ML 2.1L Diesel · A9 UGO

The vehicle most recently passed its MOT on 3 March 2026, following a minor failure regarding a non-functional offside stop lamp. Analysis of the historical data suggests a stable but reactive maintenance trend. The vehicle has a consistent pattern of failing on wear-and-tear items or minor adjustments before passing, which indicates that maintenance is often performed as a requirement for the annual test rather than through a proactive preventative schedule. While there are no indications of chronic structural failure, the frequency of minor defects suggests a need for more rigorous pre-test inspections. With 75,954 recorded miles over an eleven-year period, the vehicle has averaged approximately 6,905 miles per year. This is a moderate usage rate that typically avoids the heavy mechanical fatigue associated with high-mileage examples while also mitigating the risks of perishing components found in vehicles that have spent long periods standing. At this mileage and age, the primary mechanical concerns shift from drivetrain wear to the natural degradation of rubber and plastic components, which can harden and crack over time regardless of the distance travelled. A recurring theme in the MOT history is tyre wear and damage, with failures and advisories appearing in 2023, 2024, and 2025. This pattern suggests a potential issue with wheel alignment or a lack of regular tyre maintenance. A prospective buyer should carefully inspect the tread depth across all four tyres and look for uneven wear on the inner or outer edges, which would indicate worn suspension bushes or incorrect tracking. Furthermore, the 2023 failure for an excessively worn offside rear anti-roll bar pin or bush is a point of concern; during a test drive, listen for clunks or knocks when traversing uneven road surfaces or during low-speed cornering, as this may signal further suspension deterioration. Given the age of this Mercedes-Benz ML, attention must be paid to calendar-based maintenance not captured by the MOT. Verify the service book for evidence of transmission fluid changes and regular engine oil intervals to ensure drivetrain longevity. Inspect the brake discs for heavy surface corrosion and ensure the calipers are not binding, which can occur if the vehicle has experienced periods of inactivity. Finally, check the condition of the 12V battery and the rubber weather stripping around the doors and windows to ensure they have not perished, as this can lead to moisture ingress and subsequent electrical faults in these complex luxury SUVs.
