2023 Renault Master MLL35TW Business DCI 2.3L Diesel · MJ23 KPT

The Renault Master has successfully passed its most recent MOT test conducted in March 2026, though the history reveals a brief failure period immediately preceding the pass. The initial failure was primarily driven by safety-critical defects, specifically faulty seat belt buckles and a damaged wing mirror, which were rectified to achieve the pass. While the vehicle is currently roadworthy, the presence of these major defects alongside ongoing minor issues suggests that the maintenance regime may have been reactive rather than proactive. The transition from a failure to a pass indicates that the immediate safety concerns were addressed, but the remaining advisories regarding brake wear and tyre condition suggest a need for closer inspection of the vehicle's consumable maintenance schedule. With a recorded mileage of 31,560 miles over approximately three years, the vehicle has seen consistent, moderate usage averaging roughly 10,500 miles per annum. This is a typical profile for a commercial vehicle of this class, suggesting it has likely been used for regular delivery or trade work rather than sitting idle for extended periods. While this level of usage is generally healthy for a diesel engine, which benefits from regular operation to prevent diesel particulate filter clogging, it also means that high-wear components such as suspension bushes, wheel bearings, and drivetrain mounts will have experienced significant stress. Prospective buyers should view this mileage as a baseline for expected wear on chassis components rather than an indicator of a low-use, pampered vehicle. The advisories noted during the recent test require your immediate attention during the inspection. The front brake discs were flagged as worn, which typically manifests as a pulsating sensation through the brake pedal under heavy deceleration or an audible grinding noise. You should check for significant lipping on the outer edge of the discs and ensure the vehicle pulls up in a straight line without pulling to one side, which could indicate a binding caliper. Furthermore, the tyres were noted as worn on the edges, a common symptom of incorrect wheel alignment or heavy loading. Inspect the tyre sidewalls for uneven wear patterns and check the tread depth across the entire width of the tyre, as edge wear significantly reduces grip in wet conditions and may necessitate a four-wheel alignment check alongside premature replacement. Beyond the specific MOT advisories, you must conduct a thorough physical assessment of the vehicle's commercial utility. Given the Renault Master's nature as a workhorse, verify the condition of the load area for signs of excessive structural abuse or corrosion, particularly around the floor and door hinges. Test the seat belt mechanisms to ensure they retract smoothly and lock under tension, as the previous failure suggests these components were previously compromised. Finally, ensure that the service history is fully documented, as the three-year mark is a critical interval for fluid changes, including brake fluid and coolant, which are often overlooked in commercial maintenance schedules. Listen for any clunking from the suspension when traversing speed bumps, as this will indicate whether the front-end components are beginning to show signs of fatigue consistent with the vehicle's working life.
