2022 Renault Master LM35 Business+ Blue DCI 2.3L Diesel · SD22 FLR

The most recent MOT test results indicate a failure on 2026-04-13, with two major defects identified: both front outer drive shaft constant velocity (CV) boots being split or insecure, allowing dirt ingress and compromising the integrity of the drive shaft assemblies. This failure follows a clean MOT in April 2025 and another failure in April 2026 for parking brake inefficiency and near-side front lower suspension ball joint excessive wear. The pattern suggests a concerning trend of recurring mechanical issues, particularly in the drivetrain and suspension systems, which may indicate underlying wear or manufacturing inconsistencies. While the vehicle passed the previous MOT, the repeated failures highlight persistent problems that warrant immediate attention to prevent further deterioration and potential road safety risks. The recorded mileage of 77,184 miles for a vehicle aged four years represents a usage rate of approximately 19,296 miles annually, which is notably high for its age. Such mileage accumulation typically accelerates wear on consumables like brake pads, tyres, and suspension components, as well as drivetrain elements such as CV joints and seals. The absence of significant mileage gaps suggests the vehicle has been in regular, possibly heavy service, which can lead to faster degradation of critical systems like the CV joints and suspension ball joints. Buyers should be particularly cautious, as the CV joint failures recorded in the MOT history could escalate into costly drive shaft replacements if left unaddressed, while the ball joint wear may already be compromising steering stability and alignment. Given the recurring MOT failures, the prospective buyer must prioritise a thorough mechanical inspection of the drivetrain and suspension systems. On a test drive, listen for unusual noises from the front wheels, particularly clunking or grinding sounds when transitioning between rough and smooth road surfaces, which may indicate CV joint failure or ball joint wear progression. Inspect the front suspension for uneven tyre wear patterns, as this could signal misalignment or binding components. Additionally, check for fluid leaks around the CV boots, which may reveal the source of the ingress of dirt causing the MOT failures. Immediate servicing of the CV joints, including boot replacement and seal inspection, is essential to prevent further damage to the drive shafts and potential loss of control. The parking brake system should also be rechecked for efficiency, as the previous failure suggests potential mechanical binding or hydraulic issues that may require professional assessment. Beyond the immediate mechanical concerns, the buyer should conduct a comprehensive physical inspection of the vehicle’s structural and fluid integrity. Given the high mileage and the age of the vehicle, inspect the tyres for sidewall perishing or cracking, which can compromise safety and warrant replacement if found. Check the 12-volt battery for signs of corrosion on terminals or poor connections, as standing vehicles can exacerbate battery drain issues over time. The brake system should be inspected for corrosion on discs and linings, particularly if the vehicle has been stationary for extended periods, as this can lead to binding or reduced braking performance. Finally, since the vehicle has been driven regularly, consider a service history review to confirm compliance with manufacturer-recommended fluid changes, such as the oil, brake fluid, and coolant, which degrade over time regardless of mileage. If no service records are available, a professional fluid analysis and top-up may be advisable to ensure the vehicle remains roadworthy and safe.
