2018 Citroen C4 Cactus 1.5L Diesel · SL68 BOU

The most recent DVSA examination on 15 September 2025 resulted in a pass with no defects or advisories recorded, which is a positive immediate indicator. Reviewing the four-year MOT history, the maintenance trend appears broadly stable with no repeat failures and no escalating advisory patterns. The 2023 fail was attributable solely to an insufficient windscreen washer supply, a trivial rectification rather than a mechanical concern, and the same test noted a nearside front tyre at the legal wear limit, which would reasonably have been replaced ahead of the 2024 examination. The 2024 advisory items concerning an offside front service brake fluctuation and a slight play in the nearside front suspension arm ball joint did not progress to failure in 2025, suggesting either remedial attention has been undertaken or the wear rates remain within acceptable tolerance. Overall, the trajectory indicates a vehicle that has been maintained to a satisfactory roadworthy standard. Recorded mileage of 64,874 miles across eight years equates to approximately 8,100 miles annually, which is broadly typical for a vehicle of this age and segment. The MOT records demonstrate consistent annual usage with no significant gaps in testing and no abrupt jumps in odometer readings between examinations, providing reassurance against clock irregularities. This mileage profile places the C4 Cactus in a moderately used category, where consumable items such as brake pads, discs, tyres, and suspension components will have experienced reasonable but not excessive service life demands. The annual mileage is sufficient to keep lubricants circulating, the diesel particulate filter (where applicable) cycling, and the battery regularly charged, mitigating concerns associated with prolonged standing. Although the 2025 test was clean, the 2024 advisories warrant targeted physical inspection prior to purchase. The offside front brake fluctuation observation suggests the caliper or sliding pins may be subject to corrosion or the pads wearing unevenly, so a test drive should include firm progressive braking from moderate speed to assess for any pulling, vibration through the steering wheel, or pulsation indicating disc run-out or warped friction surfaces. The nearside front suspension arm ball joint play, if unresolved, would typically manifest as a clonking noise over speed humps or during full-lock low-speed manoeuvres, alongside uneven inner or outer tyre shoulder wear. Both front tyres should be examined for consistent tread depth across the width, and the offside front brake disc surface visually checked for lip formation and corrosion pitting, as discs on a vehicle of this age commonly approach minimum thickness around this mileage band. Given the vehicle's age and moderate mileage, several time-based deterioration factors should be independently verified regardless of the clean MOT outcome. Tyre sidewalls should be inspected closely for perishing or cracking, as rubber compounds degrade with calendar age even when tread depth remains adequate, and any tyres bearing a pre-2020 production date should be considered for replacement on safety grounds. The 12-volt battery, likely original or approaching the end of its service life, warrants a load test, particularly as C4 Cactus electrical systems are known to be sensitive to voltage drop. Brake fluid, antifreeze, and gearbox oil should be confirmed as within their respective replacement intervals according to manufacturer schedule rather than purely mileage, as these fluids degrade through chemical ageing. Additionally, with the vehicle now eight years old, the exhaust system mounting rubbers, rear flex section, and underfloor pipework should be examined for corrosion, and the coolant expansion tank and radiator plastic end tanks inspected for stress whitening, both recognised wear points on PSA-group vehicles of this generation.
