2018 Mercedes-Benz Sprinter 2.1L Diesel · RF68 FUP

The latest MOT test for the 2018 Mercedes-Benz Sprinter recorded a passing outcome on 2026-05-14, with only minor and advisory defects noted. Despite the failure in December 2024, which included a dangerous near-side front tyre with insufficient tread depth and a major defect in the central front seat belt buckle, the subsequent MOTs have been clean, suggesting a return to a stable maintenance profile. The presence of an advisory regarding front brake disc wear—though not excessively—indicates that the braking system may require closer attention over time, particularly as the vehicle continues to accumulate miles. The absence of repeated failures or persistent issues since the 2024 failure implies that any underlying mechanical wear has either been addressed or is not yet critical, but vigilance is warranted. The recorded mileage of 135,233 miles for an eight-year-old Sprinter represents a high annual usage rate of approximately 16,904 miles per year, which is notably elevated compared to typical usage patterns for this vehicle class. Such mileage accumulation typically accelerates wear on consumables like brake pads, suspension components, and drivetrain elements, as well as fluid degradation due to increased thermal and mechanical stress. The significant gap between the 2024 failure and the 2026 MOT—nearly two years—may suggest that the vehicle was either underutilised during that period or that the prior issues were resolved promptly. However, the high mileage alone does not preclude the vehicle from being roadworthy, but it does necessitate a heightened focus on consumable replacement intervals and potential hidden wear in high-stress systems like the drivetrain and exhaust. For the prospective buyer, the most critical immediate checks should centre on the braking system, given the advisory of front brake disc wear and the potential for uneven or excessive wear patterns. On a test drive, listen for any grinding noises during braking, which could indicate worn brake pads or damaged discs, and inspect the discs for signs of warping, scoring, or uneven thickness. Additionally, check for brake fluid leaks under the vehicle and ensure there is no brake shudder, which may signal warped discs or warped rotors. The near-side front tyre failure from the 2024 MOT highlights the importance of verifying tyre condition, particularly for the front tyres, which bear more load and wear. Look for uneven tread wear, cracks, or signs of dry rot, and ensure the tread depth meets or exceeds the legal minimum of 1.6mm across the central 3/4 of the tread. Beyond the immediate concerns, the vehicle’s age and high mileage warrant a thorough inspection of the suspension and drivetrain. Given the high annual mileage, inspect the suspension bushes, coil springs, and control arms for signs of stiffness, clunking noises during cornering, or excessive play, which could indicate wear or failure. Check for uneven tyre wear patterns that may suggest misalignment or suspension issues, and listen for clunking noises when driving over bumps, which could indicate worn or broken suspension components. Fluid levels, particularly the engine oil, transmission fluid, and differential fluid, should be checked and topped up if necessary, as high mileage can accelerate fluid degradation. Lastly, verify the service history for scheduled maintenance such as oil changes, timing belt replacement (if applicable), and brake system servicing, ensuring no critical intervals have been missed. A thorough inspection of the exhaust system for leaks, corrosion, or excessive noise is also advisable, as the Sprinter’s high mileage may have contributed to wear in this area.
