2016 Citroen C4 Cactus 1.6L Diesel · FD66 DKA

The vehicle most recently passed its MOT on 27 March 2026, but the overall maintenance trend has shifted from stable to declining over the last three years. While the car enjoyed a period of clean passes between 2021 and 2023, the more recent history reveals a pattern of recurring failures and advisories. The transition from simple wear-and-tear advisories to major failures regarding exhaust emissions and drivetrain components suggests that the vehicle is now entering a phase of increased mechanical degradation that requires more rigorous upkeep. The recorded mileage of 74,746 miles is typical for a ten year old vehicle, averaging approximately 7,475 miles per year. This level of usage indicates a consistent driving history without prolonged periods of standing or excessive heavy use. Consequently, the mechanical wear is predictable for its age, meaning that primary consumables such as suspension bushings, brake discs, and rubber boots are reaching the end of their natural service life and will likely require replacement soon if they have not been addressed recently. Buyers should focus their inspection on the front drivetrain and suspension. The MOT history shows a recurring failure of the offside front constant velocity boot; if this was not replaced with a high-quality part, the joint may be compromised. During a test drive, listen for rhythmic clicking or popping noises when steering at full lock. Furthermore, previous advisories regarding perishing control arm bushes and pitted brake discs indicate a need for a thorough chassis check. Listen for clunks or knocks when driving over uneven surfaces and feel for any shuddering through the brake pedal during deceleration, which would suggest the discs remain scored or warped. The recent failure for exhaust emissions is a significant point of concern and may point to a failing oxygen sensor, a clogged particulate filter, or general engine carbon build-up. Ensure the engine idles smoothly and check for any abnormal smoke during acceleration. Additionally, previous advisories for outside edge tyre wear suggest a potential issue with the front wheel alignment or tracking. Inspect the current tyres for uneven wear patterns and verify the date codes to ensure the rubber has not perished. Finally, a detailed review of the service book is essential to confirm that calendar-based fluid changes have been performed, as this is critical for mitigating the emissions issues noted in the recent history.
