2020 Citroen C4 Cactus 1.2L Petrol · PK20 PZD

The 2020 Citroen C4 Cactus presents a worsening mechanical trend, culminating in a failed MOT on 2025-11-01 at 22,010 miles before passing on the same day. The tester flagged a nearside rear tyre bulge caused by structural separation and recorded a low coolant level, both serious concerns that required immediate rectification. While the vehicle subsequently passed, the recurrence of front brake wear and the addition of a distorted nearside front wheel indicate neglecting basic consumable upkeep. The front brake pads and discs have degraded steadily, transitioning from a suspected close-to-limit advisory in November 2024 to confirmed wear a year later. A debonding nearside front suspension arm bush remains an ongoing issue, pointing to deferred mechanical maintenance rather than a one-off repair. Accumulating only 22,010 miles over six years equates to roughly 3,668 miles annually, a notably low figure that suggests extended periods of standing. The MOT records show a significant gap between June 2023 at 8,010 miles and November 2024 at 15,671 miles, representing a steady but minimal accumulation of 7,661 miles over seventeen months. Such low mileage use often leads to degraded rubber components and brake corrosion from lack of regular thermal cycling, which aligns with the worn suspension bushes and brake wear observed. The rapid accumulation of just 6,339 miles between November 2024 and the latest test in November 2025 confirms the vehicle remained in light, local use rather than long-distance touring. A prospective buyer must inspect the nearside front suspension components closely. The tester repeatedly flagged a worn and debonding frontmost suspension arm bush, which compromises steering geometry and structural integrity. Check the nearside front wheel for distortion, as an unbalanced or buckled wheel will cause vibrations and uneven tyre wear. Examine the front brake discs for scoring and measure the remaining pad depth, as both have degraded steadily over the last two years. Inspect the cooling system thoroughly, given the low coolant reading on the failed test; look for leaks around the radiator, hoses, and expansion vessel. Finally, scrutinise the nearside rear tyre sidewall, as a replacement was mandated due to structural separation, and verify the condition of the remaining tyres for age-related cracking.
