2021 Renault Master LM35 B-Ness Energy DCI 2.3L Diesel · RO71 XLC

The most recent MOT test for the 2021 Renault Master LM35 occurred on 2025-12-12, resulting in a pass despite the presence of advisories. However, the vehicle’s MOT history reveals a pattern of recurring issues rather than a clear improvement or stability. The vehicle failed twice in late 2025, with the second test on 2025-12-11 highlighting a major failure for binding front service brakes on the offside, alongside advisories for worn brake pedal rubber and under-tray damage. These defects suggest persistent mechanical wear and potential issues with brake system integrity, which could indicate either inadequate maintenance or underlying component failure. The subsequent MOT on 2025-01-06 was clean, but the earlier failures underscore a need for closer inspection of brake components and structural integrity, particularly given the vehicle’s age and accumulated mileage. The recorded mileage of 51,030 miles for a 2021 model represents a reasonable annual usage rate of approximately 10,206 miles per year, which is typical for a vehicle of this age and class. Such mileage accumulation is consistent with moderate to heavy use, particularly for a diesel-powered commercial vehicle like the Renault Master LM35, which often operates under demanding conditions. There is no evidence of significant mileage gaps or unusual patterns, but the wear observed in the MOT results—particularly on brakes and suspension elements—suggests that the vehicle has experienced consistent stress. Higher mileage increases the likelihood of wear on critical components such as brake discs, calipers, suspension bushes, and drivetrain elements, meaning the vehicle may require more frequent attention to consumables like brake fluid, lubricants, and potential fluid leaks. Given the recurring advisories and major failure on brakes, the prospective buyer should conduct a thorough inspection of the braking system. Focus on the front offside brake discs for signs of excessive pitting, scoring, or uneven wear, which could indicate hydraulic binding or mechanical misalignment. During a test drive, listen for unusual brake pedal feel—such as sponginess, binding, or excessive pedal travel—and check for vibrations or shuddering, which may signal warped discs or warped brake rotors. Additionally, visually inspect the brake calipers for binding, seized components, or fluid leaks around the brake lines. The under-tray damage noted in the advisories could also affect structural integrity or fluid containment; inspect for signs of corrosion or damage to the undercarriage, particularly around the exhaust system and suspension mounts. For the broader vehicle assessment, the buyer should also verify the condition of the 12V battery, given the vehicle’s age and potential prolonged periods of inactivity, which can lead to corrosion or discharge. Check the battery terminals for oxidation and ensure it holds a charge when tested. The 12V battery is critical for the electrical systems, including the brake servo and anti-lock braking system (ABS), so a failing battery could exacerbate the binding issues observed in the MOT. Beyond the brakes, examine the suspension for signs of worn or cracked bushes, coil springs, or strut mounts, as these can contribute to clunking noises or uneven ride quality. Finally, given the vehicle’s diesel engine and the potential for prolonged standing, pay attention to the condition of the engine oil and coolant—both should be checked for degradation or contamination, as diesel engines are particularly susceptible to sludge formation and coolant breakdown over time. If the vehicle has been used for commercial purposes, verify any service records for scheduled maintenance, such as the timing belt replacement (if applicable) and regular fluid top-ups, to ensure long-term reliability.
