2012 Citroen C4 2.0L Diesel · AY62 FSJ

A sudden and comprehensive failure of multiple critical electronic and emission systems defines the current state of this vehicle, following a period of relative stability. The MOT test on 6 October 2025 resulted in a failure due to major defects involving exhaust emissions exceeding limits, an inoperative or malfunctioning engine management light, and faults indicated by the ABS and ESC warning lamps. Additionally, the electronic parking brake was recorded as defective. This represents a significant downturn in roadworthiness compared to the clean pass recorded in 2024 and the minor advisories of previous years. With 143,874 miles recorded over approximately 14 years, the vehicle has averaged around 10,277 miles per year, which is typical for its age. This level of usage implies that drivetrain components, suspension bushings, and braking systems have been subjected to standard wear and tear. At this mileage, there is an increased likelihood of degradation in rubber components and the potential for wear-related fatigue in the chassis and engine peripherals. Prospective buyers must verify the resolution of the major failures flagged in October 2025. Specifically, the electronic parking brake must be tested for full operational capacity, and the dashboard should be monitored for any active ABS or ESC warning lamps, as these indicate faults in the vehicle's stability and braking safety systems. The engine management light and exhaust emissions failure suggest underlying issues with the combustion or filtration system; buyers should check for irregular idling or visible smoke from the exhaust during a test drive. Attention should also be paid to the front suspension and steering, given the historical records of rough steering in 2019 and play in both the nearside and offside front anti-roll bar linkage ball joints in 2023. During a test drive, listen for knocking or rattling sounds when traversing uneven road surfaces or speed bumps, which would indicate that the anti-roll bar linkages require replacement. Ensure the steering feels smooth and consistent when rotating the wheel at low speeds to confirm that previous steering roughness has been addressed.
