2005 Mercedes-Benz ML 2.7L Diesel · SF05 EFN

The vehicle presents a concerning maintenance history that suggests a pattern of reactive rather than proactive care. While the Mercedes ML technically passed its most recent test in March 2023 at 132,738 miles, the failure just two weeks prior reveals significant neglect of the suspension system. The 2023 failure flagged multiple critical issues including worn anti-roll bar bushes, track rod end play, and suspension arm ball joints. The transition from a multi-point failure to a pass over just eight miles indicates that the owner only addressed mechanical faults when legally compelled by the MOT tester. At 21 years old, the recorded mileage of 132,738 miles represents an average of approximately 6,300 miles per year, which is consistent with low-use patterns. However, the data shows a significant gap in testing between December 2021 and February 2023, during which the vehicle covered only 1,663 miles. This low annual mileage often correlates with the degradation of rubber-based components, as evidenced by the recurring issues with split CV boots and brake hose corrosion that appeared across the 2020 and 2021 records. The lack of frequent inspections during these periods likely allowed minor wear to escalate into the mechanical failures. A buyer must conduct a thorough physical inspection of the front-end geometry and underbody components. The persistent central front oil leak noted in 2023 requires close monitoring to ensure it does not indicate a failing front main seal or pump housing. Given the history of corrosion on brake hose ferrules and steering pipes, the integrity of all hydraulic lines should be checked for perished rubber or internal structural rot. Furthermore, the previous failure of a fractured offside rear coil spring in 2020 and the repeated wear on anti-roll bar components suggest the suspension system is nearing the end of its service life and may require further expensive investment to maintain roadworthiness.
