2018 Mercedes-Benz X 2.3L Diesel · LA13 OOT

High annual mileage and a recent significant failure pattern define the mechanical profile of this vehicle, most notably evidenced by the failure on 16 December 2025. While the vehicle secured a pass on 17 December 2025, the preceding day's test revealed critical safety issues, including dangerous tyre tread depths on both rear tyres and an inoperative engine malfunction indicator lamp. The presence of a failed engine MIL (Malfunction Indicator Lamp) is a significant point of concern, as the inability to monitor engine management faults can mask serious underlying mechanical or emissions issues. The recorded mileage of 159,655 over approximately eight years indicates a high-intensity usage pattern, averaging nearly 20,000 miles per year. This level of accumulation suggests the vehicle has likely been used for significant long-distance transit rather than short urban trips. Mechanically, this consistent high-mileage application typically accelerates the wear on consumable components and structural elements. The testing history shows a relatively stable period of passes between 2021 and 2025, but the sudden appearance of multiple failures in late 2025 suggests that component degradation is currently accelerating. Prospective buyers should focus their physical inspection on the engine management system and the rear axle area. Given the recent failure of the engine MIL, it is essential to verify that the dashboard warning lights function correctly and that no fault codes are present in the engine control unit. Furthermore, the advisory from December 2022 regarding an oil leak, while described as not excessive at the time, warrants a thorough inspection of the engine bay and undercarriage for fresh seepage. During a test drive, look for any signs of oil misting around gaskets or pooling on the undertray, and listen for any irregular engine rhythms that might indicate the previously flagged electronic faults. The tyre history, including the dangerous failures in late 2025 and the advisory for edge wear on the nearside front tyre in 2022, suggests a potential for alignment or suspension geometry issues. On a test drive, pay close attention to the steering response and stability. Check for any pulling to one side under braking or steady acceleration, and listen for knocking or clunking sounds from the suspension when driving over uneven surfaces, which could indicate worn bushes or dampers. The history of uneven tyre wear and recent tread depth failures necessitates a close inspection of the current tyre condition and the integrity of the steering and suspension linkages.
