2020 Citroen Relay 2.2L Diesel · OU20 NNF

The most recent MOT test on the Citroën C-Series Relay was conducted on 2026-06-29, resulting in a passing outcome with two minor defects—one related to the near-side windscreen wiper blade and another to a minor windscreen damage that does not impair driver visibility. While the vehicle has passed the latest test, the history reveals a pattern of recurring issues that warrant cautious consideration. The failed tests in 2024 and 2025 highlight persistent problems with lighting (headlamps), side repeaters, and the parking brake system, alongside a significant defect in the rear seat belt retractor in 2026. These failures suggest that while the vehicle may currently be roadworthy, underlying mechanical or electrical issues could re-emerge without proactive maintenance. The advisories from 2024 regarding rear shock absorber misting indicate wear that could progress over time, particularly if the vehicle experiences rough or uneven road conditions, which may exacerbate suspension degradation. The recorded mileage of 20,536 miles for a 2020 model represents a relatively low annual usage rate of approximately 3,423 miles per year, which is unusually low for its age. Such low mileage often correlates with periods of extended stationary use, particularly if the vehicle was parked for prolonged durations without regular movement. This can lead to specific wear patterns—such as corrosion from standing fluids in brake systems, caliper binding, or fluid degradation in hydraulic components—where motion would otherwise mitigate these effects. Conversely, if the mileage were higher, wear on consumables like brake pads, suspension components, and drivetrain elements would be more pronounced, but the current low mileage may mask some of these issues. The absence of recent high-mileage accumulation suggests that the vehicle has not been subjected to the same levels of stress as similarly aged models with higher usage, but this also raises questions about whether the owner has been maintaining it in a manner typical of its age group. For a prospective buyer, the most critical areas to inspect are the electrical and mechanical systems that have repeatedly failed or been flagged in previous MOTs. Begin with a thorough check of the lighting system, including all headlamps, side repeaters, and indicator lights, ensuring no further defects exist and that all bulbs are functional. The parking brake system should be tested for efficiency—if the vehicle pulls to one side or requires excessive force, it may indicate a failing hydraulic or mechanical component that could lead to a future failure. The rear seat belt retractor, which failed in 2026, should be inspected for signs of mechanical failure or wear, as this could pose a safety risk if the retractor does not deploy correctly in a crash. During a test drive, listen for unusual noises from the suspension, particularly around the rear shocks, as misting can indicate impending failure, and clunking or excessive bouncing may signal worn suspension components. Additionally, check for any fluid leaks under the vehicle, especially around the brakes and exhaust, which could reveal underlying issues with seals or hoses. Beyond the recurring defects, the vehicle’s low mileage and age necessitate a focus on age-related wear and potential standing-related corrosion. Inspect the tyres for signs of sidewall cracking or perishing, which can occur even at low mileage if the rubber has been exposed to prolonged environmental conditions. Check the brake discs for corrosion or binding, as standing brake systems can cause rust buildup on discs and calipers, leading to reduced braking efficiency. Verify the condition of the 12V battery, ensuring it holds a charge and does not show signs of corrosion or swelling, as low usage can lead to battery degradation over time. Fluid levels should be checked, with particular attention to the brake fluid, which can degrade over time even without use, and the coolant, which may have sat stagnant in the system. Finally, consult the service records to confirm that the vehicle has received the recommended fluid top-ups and component replacements at the manufacturer-recommended intervals, as low mileage does not exempt the vehicle from these checks. If service history is sparse or missing, prioritise a professional inspection to confirm that all critical systems are in good order before proceeding with purchase.
