2009 Mercedes-Benz GL 3.0L Diesel · YC59 XJD

The most recent MOT test on 2025-10-29 confirms the vehicle remains roadworthy, with no defects recorded at 173,952 miles. This marks the fourth consecutive pass in the last two years, suggesting a stable maintenance pattern without recurring failures. The absence of advisories or defects in the latest test indicates the vehicle has not experienced any critical mechanical or safety-related issues since the previous inspection just nine months prior. However, the 2024-01-05 failure—though without recorded defects—stands out as an anomaly, as it occurred just three days before the subsequent pass at 160,221 miles, implying either a minor oversight or a temporary procedural issue rather than a persistent problem. The mileage progression shows consistent usage, averaging roughly 10,230 miles annually, which aligns with typical expectations for a vehicle of this age. There are no prolonged gaps in service or abrupt spikes that would indicate neglect or heavy intermittent use. The interval between tests remains standard, with the most recent pass occurring just under a year ago, well within the DVSA’s recommended 12-month cycle. This regularity suggests the vehicle has been kept in active circulation without prolonged periods of inactivity, which could otherwise accelerate wear on components like suspension bushes or fuel system seals. Given the clean MOT history, a buyer should prioritise an in-person inspection of high-wear areas that are not directly tested in the MOT but are critical for long-term reliability. The suspension—particularly the rear coil springs and bushes—should be examined for excessive sagging or cracking, as these components are prone to fatigue at this mileage. Brake systems, including rear calipers and discs, warrant close scrutiny, as binding or uneven wear can develop without triggering a fail. Structural integrity, especially around the wheel arches and sills, must be checked for corrosion, as Mercedes-Benz models of this era are susceptible to rust-related failures. Additionally, the fuel system, including injectors and fuel lines, should be inspected for leaks or clogging, as these issues often manifest intermittently and may not always appear in a standard MOT.
