2018 Mercedes-Benz Sprinter 2.1L Diesel · RF68 FSZ

The most recent MOT test conducted in December 2025 resulted in a pass, although it introduced minor defects regarding the windscreen and registration plate lamp, alongside a notable advisory. Looking at the overall maintenance trend, the vehicle appears relatively stable, having maintained clean MOT records for several years following a significant failure in 2022. That previous failure, involving the NOx sensor and the Malfunction Indicator Lamp, suggests that the engine management and emissions systems required substantial repair to meet legal standards. The recent emergence of a suspension advisory indicates that the vehicle is now entering a phase where mechanical wear is becoming more evident. The recorded mileage of 125,023 miles over an eight-year period represents a high annual usage rate of approximately 15,600 miles. This level of utilization is typical for a commercial workhorse but implies that the drivetrain and chassis components have been subjected to significant stress. High-mileage vehicles of this type often face accelerated wear on heavy-duty consumables, including clutch assemblies, brake components, and various suspension bushings. Buyers should be prepared for the possibility of upcoming maintenance requirements for parts that are traditionally subject to fatigue after exceeding the 100,000-mile threshold. A primary area of concern for a prospective buyer is the advisory regarding the nearside front lower suspension arm ball joint exhibiting slight play. During your test drive, pay close attention to the steering response and listen for any metallic clunking or knocking sounds when driving over speed bumps or uneven road surfaces. Excessive play in a ball joint can lead to imprecise steering, increased vibration through the steering wheel, and accelerated, uneven wear on the front tyres. It is advisable to have a qualified mechanic inspect the condition of the ball joint and the integrity of the surrounding suspension arms to determine if immediate replacement is necessary to prevent a future MOT failure. Additionally, given the history of emissions-related failures, you must verify that the engine management system is operating correctly. Ensure that no warning lights, specifically the engine management light, illuminate on the dashboard during operation or after the engine has been cycled through several heat stages. Given the high mileage and commercial usage profile, you should also conduct a thorough visual inspection for any signs of oil or coolant leaks around the engine block and check the condition of the brake discs for excessive pitting or thinning. Verifying that the service history shows consistent, timely oil changes is essential to ensure the long-term health of the diesel engine under these high-mileage conditions.
