2018 Mercedes-Benz X 2.3L Diesel · LL10 SEB

A trend of emerging wear on braking components and a newly noted engine oil leak defines the current mechanical state of this vehicle, following a period of clean test results. While it passed its latest inspection on 28 October 2025, the shift from a defect-free 2024 record to multiple advisories suggests an increase in component degradation. The history indicates a pattern of brake pad depletion across both axles over the last few years, now culminating in the pitting and scoring of the front discs. Recorded mileage stands at 74,607 miles over approximately eight years, averaging roughly 9,326 miles per annum. This represents a typical usage profile for this vehicle type, suggesting consistent road use rather than prolonged periods of inactivity or extreme high-mileage stress. Mechanically, this level of accumulation typically coincides with the expected wear cycle for friction materials and seals, which aligns with the current advisories recorded in the DVSA history. Attention must be paid to the braking system, specifically the front discs and pads flagged in the latest test. During a test drive, the buyer should feel for any pedal judder or vibration under braking, which would indicate that the pitting or scoring of the discs has progressed. The history of thin pads on both the rear in 2023 and the front in 2025 indicates that the braking consumables are reaching the end of their service life and will likely require replacement. The oil leak noted in the October 2025 test requires a physical inspection of the engine bay and underbody. While recorded as not excessive, the buyer should look for fresh oil residue around the gaskets and sump. During the test drive, check for any smell of burning oil when the engine reaches operating temperature, which occurs when leaking fluid contacts the exhaust manifold. Verification of the leak source is essential to determine if it is a minor seepage or a defect requiring more significant mechanical intervention.
