2014 Citroen C4 1.6L Petrol · WJ14 AEP

The vehicle's roadworthiness status is currently poor, with the maintenance trend showing a significant worsening in mechanical condition. The most recent test on 23 July 2025 at 125,687 miles resulted in a failure involving serious engine and environmental issues. The tester flagged excessive carbon monoxide emissions at both idle and fast idle, alongside a coolant leak that poses a risk to the environment. This failure, combined with a total failure of all four tyres due to being worn to the legal limit, damage, or perishing, suggests a period of significant neglect regarding both engine health and basic consumable maintenance. The mileage accumulation is consistent with a vehicle of this age, averaging approximately 10,474 miles per year. The data shows a steady climb from 24,206 miles in February 2017 to the current 125,687 miles. While the usage pattern is typical, the frequency of failures has increased as the mileage has risen. The gap between the 2024 pass at 112,879 miles and the 2025 failure indicates that while the vehicle was being driven regularly, the necessary preventative maintenance was not being performed to keep the vehicle within legal operating standards. A prospective buyer must conduct a thorough inspection of the cooling system to identify the source of the coolant leak flagged in July 2025. The engine's emission levels suggest potential issues with the fuel system, sensors, or catalytic converter, which require professional diagnostic investigation. Given the recurring issues with brake discs being pitted, scored, or corroded—noted in 2019, 2020, 2021, 2022, and 2023—the braking system should be checked for component longevity and service intervals. The history also reveals a pattern of deferred tyre replacement. Multiple tests between 2021 and 2025 flagged tyres that were either worn to the legal limit, damaged, or perishing. This indicates a tendency by previous owners to run consumables to their absolute limit. Beyond the tyres, the repeated failures regarding inoperative registration lamps and headlamp aim suggest that minor electrical and alignment checks were frequently overlooked. Any purchase should be preceded by a mechanical assessment of the engine's combustion efficiency and the integrity of the cooling circuit.
