2018 Ford Fiesta 1.0L Petrol · BJ18 AAF

The 2018 Ford Fiesta’s most recent MOT test on 2026-03-17 resulted in a clean pass, marking a return to full compliance after a single failure in 2024-03-01. While the vehicle has otherwise maintained a consistent pass record over the preceding three years, the 2024 failure—particularly the supplementary restraint system (SRS) warning lamp fault—suggests a recurring or persistent issue within the airbag deployment mechanism or wiring harness, which may warrant further investigation. The absence of subsequent failures since then indicates either effective rectification or a less critical underlying cause, but the advisory from that test remains a notable anomaly. For buyers, this suggests the vehicle’s overall maintenance trend is stable but not without underlying considerations, especially regarding the SRS subsystem’s longevity and the near-side rear tyre’s minor but persistent defect. The recorded mileage of 47,816 miles for a vehicle aged eight years represents a notably low annual usage rate of approximately 5,977 miles per annum, which is unusually low for a car of this age and model. Such low mileage often correlates with periods of prolonged inactivity, particularly if the vehicle was stored rather than driven regularly, which can lead to specific wear patterns and potential issues. For instance, standing for extended periods can cause brake discs to corrode or develop binding calipers due to moisture ingress, while suspension components like coil springs and suspension bushes may degrade from lack of movement, potentially leading to clunking noises upon acceleration or cornering. Additionally, fluids such as brake fluid and differential oil can degrade over time when not circulated, risking stiffness in hydraulic systems or increased friction in the transmission. The low mileage also raises questions about the vehicle’s exposure to environmental factors, such as road salt or corrosive conditions, which could accelerate wear on undercarriage components or the exhaust system. Given the vehicle’s clean MOT history aside from the 2024 SRS fault and the near-side rear tyre cut, the prospective buyer should conduct a thorough physical inspection to address both immediate and long-term concerns. First, visually inspect the near-side rear tyre for any signs of further deterioration beyond the recorded cut, such as cord exposure or internal damage, which could compromise tyre integrity and pose a safety risk. During a test drive, listen for unusual noises from the suspension, particularly clunks or rattles, which may indicate worn suspension bushes or broken coil spring mounts. Check for uneven tyre wear patterns, which could signal misalignment or suspension issues, and verify that the brakes operate smoothly without any shuddering or grinding noises when applying pressure. Additionally, examine the brake discs for corrosion, warping, or binding calipers, as standing can exacerbate these conditions. The SRS fault from 2024 should prompt a check of the airbag system’s wiring and connectors, ensuring no loose or corroded components that could lead to future failures. Finally, given the vehicle’s age and low mileage, pay particular attention to the tyre sidewalls for signs of perishing or cracking, which can compromise structural integrity and safety, and test the 12V battery for voltage output and overall health, as prolonged inactivity can lead to diminished capacity. For a vehicle of this age and mileage profile, the buyer should also prioritise time-based maintenance checks. Given the low mileage, the Ford Fiesta’s service history should be scrutinised for any missed or delayed intervals, particularly for fluid servicing—such as the brake fluid flush, differential oil change, and coolant replacement—which are critical for maintaining system performance and preventing corrosion or hydraulic failure. The brake fluid, in particular, should be replaced every five years or more frequently if the vehicle has been stationary for extended periods, as moisture absorption can lead to brake fluid cavitation and reduced braking efficiency. Similarly, the engine oil and filter should be checked for degradation, with a full service recommended if the vehicle has been unused for more than a year, as oil can thicken and lose its lubricating properties. The exhaust emissions system should also be inspected for leaks or discolouration, as prolonged idling or low-mileage usage can lead to carbon buildup or catalytic converter inefficiency. Lastly, the vehicle’s structural integrity should be assessed for any signs of rust, particularly around the undercarriage and wheel arches, as low-mileage storage in harsh conditions can accelerate corrosion. A comprehensive inspection by a qualified mechanic would be advisable to confirm the absence of hidden issues and ensure the vehicle’s roadworthiness and longevity.
