2023 Renault Master LM35 Business Blue DCI 2.3L Diesel · MA23 VWK

The 2023 Renault Master LM35 recorded a failed MOT on 2026-06-22 with a major defect related to the parking brake efficiency, which fell below the DVSA’s specified standards. This marks the vehicle’s first recorded MOT failure in its history, though the preceding test on the same date, 2026-06-22, was passed without any defects. While the immediate trend is concerning, the absence of further failures or advisories in the intervening period suggests that the issue may have been addressed or is a one-off anomaly. However, the presence of a major defect necessitates immediate attention to ensure roadworthiness, particularly given the vehicle’s operational requirements—especially if it is used for commercial or regular passenger transport where a functional parking brake is critical. The recorded mileage of 81,581 miles for a three-year-old vehicle represents a high annual usage rate of approximately 27,194 miles per annum, which is notably elevated for its age and class. Such mileage accumulation typically accelerates wear on consumables like brake pads, suspension components, and drivetrain elements, as well as fluids such as brake fluid and coolant, which degrade more rapidly under sustained high usage. Additionally, prolonged periods of high mileage without significant service intervals may lead to increased risk of mechanical fatigue in structural components, such as suspension bushes or exhaust systems, and accelerated tyre wear patterns. The absence of mileage gaps suggests consistent, possibly heavy use, which may have contributed to the observed parking brake failure, as this system is particularly susceptible to wear from frequent engagement and disuse. Given the recent MOT failure concerning the parking brake, the prospective buyer should commence an immediate inspection of the vehicle’s braking system, focusing on the parking brake mechanism itself. The parking brake lever should be checked for smooth operation, with no unusual resistance or binding, and the cable or hydraulic system should be inspected for signs of corrosion, leaks, or excessive wear. On a test drive, listen for any unusual noises from the rear wheels, particularly when the parking brake is engaged, as this may indicate binding calipers, seized parking brake shoes, or worn brake discs. If the parking brake is not functioning correctly, the vehicle may exhibit erratic movement when stationary, or the driver may need to apply the main brake repeatedly to hold the vehicle in place. Additionally, verify that the parking brake is fully released when the ignition is turned off, as a stuck mechanism could pose a safety hazard. Beyond the parking brake, the buyer should conduct a comprehensive inspection of the vehicle’s suspension and drivetrain, given the high mileage. Check the suspension for signs of worn or cracked coil springs, damaged suspension bushes, or excessive play in the struts, which may manifest as clunking noises when driving over bumps or uneven surfaces. Inspect the wheel bearings for excessive play or grinding noises, and examine the tyres for uneven wear patterns, which could indicate misalignment or suspension issues. The tyres should also be checked for sidewall cracking or perishing, which can occur even at moderate mileages due to age and exposure to UV light, particularly if the vehicle has been stored in direct sunlight. Furthermore, given the vehicle’s age and usage, the buyer should verify the condition of the 12V battery, as prolonged disuse or heavy reliance on the parking brake can lead to battery drain. Finally, ensure that all fluids, including brake fluid, coolant, and transmission fluid, are at the correct levels and free from contamination, as high mileage accelerates fluid degradation. If possible, obtain a service history to confirm that scheduled maintenance, such as brake pad replacement and fluid top-ups, has been conducted according to the manufacturer’s recommendations.
