2019 Citroen C4 1.5L Diesel · MP19 XWB

The vehicle is currently roadworthy having passed its latest MOT in October 2025 at 52,346 miles. However, the maintenance trend shows a recent period of instability evidenced by a significant failure just two days prior to that pass. The tester flagged critical issues including excessive exhaust emissions, visible smoke from the exhaust, misaligned headlamps, and a failed registration plate lamp. While the subsequent pass indicates these were rectified, the presence of visible smoke and high emissions suggests a potential fuel mixture issue or a sensor fault that requires close monitoring. The mileage pattern is consistent with typical low-use cycles, averaging approximately 7,500 miles per year over its seven-year life. The record shows steady progression from 26,554 miles in October 2022 to 52,346 miles in 2025, representing a gain of 25,792 miles over three years. This low mileage generally reduces mechanical wear on the drivetrain and engine, though the long intervals between tests can sometimes lead to component degradation or fluid breakdown if the vehicle sits stationary frequently. A buyer should pay close attention to the braking and exhaust systems based on historical recurring faults. The 2022 test identified thin brake pads and pitted discs across the axles, which is standard consumable wear but highlights a need for regular inspections. The 2024 advisory also noted front tyres worn on the edges, which often points to an alignment issue or worn suspension bushes. Given the October 2025 failure regarding emissions and smoke, a physical inspection of the exhaust system and the diesel particulate filter condition is essential to ensure the engine is not suffering from ongoing combustion issues or carbon buildup.
