2013 Mercedes-Benz ML 2.1L Diesel · AO12 ADE

The vehicle presents a marginal roadworthiness status where the maintenance trend shows a concerning shift toward mechanical neglect. While the vehicle passed its November 2025 test at 137,207 miles, it followed a significant failure just five days prior at 137,140 miles. The recurring presence of a deteriorated nearside front CV boot and failing tyre components indicates a failure to address critical safety defects promptly. The persistence of a coolant warning light during the most recent test suggests an ongoing cooling system issue that remains unaddressed despite the MOT pass status. The mileage accumulation is consistent with the vehicle's age, averaging approximately 10,500 miles per year over its thirteen-year life. Between October 2024 and October 2025, the vehicle covered roughly 7,700 miles, representing a steady usage pattern. However, the transition from a clean record in 2022 at 109,511 miles to multiple failures in 2025 suggests that as the vehicle has reached this higher mileage threshold, components are only being serviced at the point of failure rather than through proactive preventative maintenance. A buyer must conduct a thorough inspection of the front drivetrain and cooling system. The repeated failure of the nearside front CV boot necessitates a close look at the drive shaft itself for internal damage, as grease leakage often leads to joint seizure. The central oil leak from the transfer box noted in 2023 and 2024 must be verified to ensure it has not escalated into a high-volume seal failure. Furthermore, the persistent coolant light demands a pressure test of the cooling system to rule out a head gasket or thermostat failure, which poses a risk of overheating if left ignored.
