2004 Mercedes-Benz ML 2.7L Diesel · YK04 AGJ

The vehicle is currently roadworthy but the maintenance history reveals a persistent trend of structural and fluid degradation. While the most recent test in September 2025 at 122,719 miles was a pass, it followed a significant failure just eleven days prior. That failure identified critical structural weaknesses, specifically significantly reduced seat belt anchorage sills on both the nearside and offside front. Although these appear to have been rectified, the recurring presence of a non-excessive oil leak and general underbody corrosion indicates a vehicle that is aging against its mileage. At 22 years old, the recorded 122,719 miles represent low usage, averaging approximately 5,500 miles per year. This low-use pattern is consistent across the decade, with only 21,000 miles covered between September 2021 and September 2025. However, the low mileage does not prevent the natural degradation of rubber components and metalwork. The record shows the vehicle has likely sat for extended periods, which often correlates with the observed corrosion on the brake pipes and suspension components despite the low distance driven. A buyer must prioritise a thorough inspection of the structural integrity, specifically the sills and mounting points, following the major failure in 2025. The tester has repeatedly flagged corroded offside front brake pipes in 2019, 2020, and 2025, suggesting a systemic issue with underbody rust that has not been fully addressed. The persistent oil leak noted in nearly every test since 2021 requires a diagnostic check to determine if it is a simple seal or a more costly failure. Furthermore, the history of broken springs and worn anti-roll bar bushes indicates the suspension system is reaching its fatigue limit and may be in need of comprehensive replacement to ensure stable handling.
