2018 Fiat Fiorino 1.2L Diesel · YJ68 HKY

The 2018 Fiat Fiorino’s most recent MOT test on 2025-10-29 resulted in a failure, primarily due to an active Engine Management System (EMS) fault indicated by the Malfunction Indicator Lamp (MIL), alongside persistent minor and advisory issues. This failure contrasts sharply with the two prior MOTs in 2024, both of which passed without defects, suggesting a concerning deterioration in the vehicle’s internal systems. The failure indicates a critical malfunction that has not been resolved, which could stem from a failing fuel injector, sensor, or wiring issue—all of which require immediate attention to prevent further engine damage or emissions non-compliance. The recurring tyre wear advisories, particularly on the front tyres, also warrant closer scrutiny, as they may reflect alignment or suspension irregularities exacerbated by the high mileage and potential previous maintenance neglect. The recorded mileage of 114,477 miles for a vehicle aged eight years represents an annual usage rate of approximately 14,310 miles, 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 the clutch, transmission fluids, and exhaust system. The absence of significant mileage gaps between MOTs suggests the vehicle has been in regular use, likely contributing to the observed wear patterns and the recent engine fault. The front tyre wear advisories, in particular, may indicate misalignment or excessive camber angles, which can be exacerbated by aggressive driving or poor road conditions. The rear tyre advisory from 2022 also hints at uneven load distribution or suspension wear, which could be compounding the front tyre issues. Given the recent MOT failure and the recurring advisories, the prospective buyer should prioritise a thorough mechanical inspection to confirm the root cause of the engine fault. The symptoms of a failing EMS system may include rough idling, reduced power, or a persistent illuminated MIL, which should be investigated by a qualified mechanic. During this inspection, the technician should verify the fuel injectors, oxygen sensors, and wiring harness for corrosion or damage, as well as check for any signs of oil leaks that could indicate a failing piston ring or valve train issue. The front tyre wear patterns should be examined for alignment or suspension defects, with particular attention to the strut mounts, coil springs, and suspension bushes for signs of wear or failure, which could lead to uneven tyre wear or handling instability. Additionally, the buyer should inspect the brakes for binding calipers, warped discs, or excessive pad thickness, as the 2021 advisory suggests ongoing wear that may require replacement soon. For the buyer’s immediate action, if the engine fault cannot be resolved promptly, the vehicle should not be driven until the issue is addressed to avoid further damage or emissions violations. In the interim, the advisories on tyre wear should be monitored closely, with the front tyres replaced if they reach the legal limit to prevent hydroplaning or reduced traction. The rear tyre advisory from 2022 should prompt a check of the vehicle’s load distribution and suspension components, as uneven tyre wear often indicates underlying mechanical issues. Beyond the MOT, the buyer should also conduct a basic physical inspection of the vehicle, focusing on the tyre sidewalls for signs of perishing or cracking, which can indicate age-related degradation despite the low recorded mileage. The 12V battery should be tested for charge capacity, as prolonged standing or infrequent use can lead to corrosion or internal failure, particularly in older vehicles. Lastly, the fluid levels—particularly the brake fluid, coolant, and transmission fluid—should be checked and topped up if necessary, as these fluids degrade over time and should be replaced according to the manufacturer’s service schedule, even if the vehicle has not been driven extensively.
