2012 Mercedes-Benz ML 3.0L Diesel · KV12 GVL

The vehicle failed the most recent 2025‑12‑04 MOT, with a headlamp aim defect and a rear prop shaft flexible coupling showing slight deterioration, indicating it is not presently roadworthy despite the oil leak being recorded as not excessive. Earlier tests from 2022 onward have been largely successful, but the recurring coupling issue and the 2024 omission of a rear wheel fixing suggest a modest worsening of suspension and structural condition rather than steady improvement. Mileage has risen from 30,027 miles in June 2015 to 117,320 miles by December 2025, averaging roughly 8,380 miles per year, which aligns with typical usage for a 14‑year‑old Mercedes‑Benz ML. A notable jump occurred between 2017 and 2020 when the odometer climbed from 45,874 to 84,672 miles, reflecting more intensive use during that three‑year span, while the subsequent yearly increments from 2020 to 2025 have been more consistent. A buyer should prioritize inspection of the rear prop shaft coupling for play or wear, verify the integrity of the rear wheel fixing bolts that were missing in the 2024 test, and examine the rear coil spring and associated bushes given the 2021 fracture and recent deterioration. Attention should also be given to the rear brake assembly, as pads were noted as possibly low in 2015, and to tyre condition, particularly the stepped edge wear recorded in 2015. Finally, confirm headlamp alignment and check for any excessive oil leakage or structural rust around the chassis and exhaust components.
