2021 Citroen Relay 35 HVY L4H3 ENT Bhdi SS 2.2L Diesel · RF03 RAM

The Citroën Relay 35 HVY’s most recent DVSA MOT test on 2025-09-05 returned a clean pass with no recorded defects or advisories, following an identical outcome from the preceding test on 2024-08-31. This consistent pass record over two consecutive years suggests a stable maintenance history, with no evidence of recurring mechanical issues, progressive wear, or emerging fault patterns. The vehicle’s adherence to roadworthiness standards without fail indicates that while it may not have undergone scheduled servicing, the fundamental structural and functional components—such as brakes, lights, exhaust emissions, and steering—are currently operating within acceptable limits. This stability is particularly reassuring given the vehicle’s relatively low recorded mileage, which may imply either minimal operational stress or prolonged periods of inactivity, both of which can reduce wear rates on certain systems. The recorded mileage of 5,512 miles for a 2021 model represents a notably low annual usage rate of approximately 1,102 miles per year, which is significantly below the average for vehicles of this age and class. Such low mileage can arise from factors like infrequent use, seasonal storage, or operational constraints, but it also carries implications for component wear. Lower mileage may mitigate some wear on consumables like brake pads and fluids, but it can also exacerbate issues related to standing corrosion, particularly in the brake system, suspension, and underbody components. For example, standing brake discs may develop corrosion or binding calipers due to prolonged idleness, while suspension bushes and coil springs could show signs of stiffness or play if not regularly cycled. Additionally, the vehicle’s low usage may mean that time-based fluid degradation—such as in the coolant, brake fluid, or differential oil—has not been addressed within the recommended service intervals. Given the vehicle’s clean MOT history and low recorded mileage, prospective buyers should conduct a thorough physical inspection to address potential age- and usage-related risks. First and foremost, examine the tyres for signs of sidewall perishing or cracking, which can compromise structural integrity and safety, especially if the vehicle has been stored for extended periods. Check the 12V battery for signs of corrosion on terminals, swelling, or reduced cranking power, as low usage can lead to battery discharge and internal degradation. Inspect the brake system for corrosion on discs and linings, particularly in the rear where standing conditions often worsen corrosion. Listen for any unusual noises during a test drive—such as grinding when braking, clunking from suspension bushes, or whining from power steering—these could indicate emerging wear or binding components that warrant immediate attention. Additionally, verify that the service book contains any recorded maintenance stamps, particularly for fluid servicing, as time-based fluid degradation is a critical factor in vehicles that have not been driven regularly. For fluid servicing, prioritise checking the coolant system for any signs of contamination or sludge, as prolonged inactivity can accelerate corrosion and overheating risks. The brake fluid reservoir should be inspected for contamination or moisture ingress, which can compromise braking performance. The differential oil and transmission fluid should also be evaluated, with a recommendation to replace them if they have not been serviced within the manufacturer’s recommended intervals, which for many diesel models like the Relay 35 could be around 60,000 to 100,000 miles or every two years, whichever comes first. Finally, a thorough visual inspection of the underbody for rust or corrosion is essential, as low mileage can lead to standing water accumulation, which accelerates rust formation in vulnerable areas such as the wheel arches, exhaust system, and suspension mounts. If any of these checks reveal concerns, it is advisable to address them promptly to prevent further deterioration and maintain the vehicle’s long-term reliability.
