2016 Citroen C4 Cactus 1.2L Petrol · AV16 PYO

The 2016 Citroen C4 Cactus presents a stable and improving maintenance trend, culminating in a clean pass on 27 January 2026 at 64,257 miles with zero defects recorded. That result is particularly significant because it follows a failure on 1 July 2024 at 58,467 miles, where the tester flagged a Lambda reading outside specified limits after the second fast idle and an exhaust leak affecting front emissions. The subsequent pass on 2 July 2024 at 58,471 miles, just four days later, indicates the exhaust issue was rectified promptly. Since then, three consecutive clean passes suggest the car has been maintained to a consistent standard with no recurring mechanical or emissions faults. The mileage accumulation of roughly 6,426 miles per year is typical for a ten-year-old vehicle and does not raise concerns about excessive wear or prolonged standing. The record shows a steady progression from 55,370 miles in July 2023 to 64,257 miles by January 2026, with no anomalous gaps or sudden jumps in usage. The only notable detail is the slight discrepancy between the 2024 failure and pass occurring within four days of each other at nearly identical readings, which is consistent with a retest following a repair rather than a data anomaly. Overall, the service history is sparse but clean, with no pattern of neglected consumables or repeated component failures. From a buyer's perspective, the exhaust system warrants close attention during any in-person inspection. The 2024 failure points to a Lambda sensor or exhaust leak issue that, while apparently resolved, could recur if the repair was temporary or if the catalytic converter is degrading with age. Check for visible corrosion on the exhaust manifold, flexi-pipe, and back box, and monitor live Lambda data during a test drive to confirm the sensors are operating within range. The suspension and braking systems have not been flagged in any test, but at 64,257 miles, worn suspension bushes, tired coil springs, and uneven brake disc wear are common on this platform. Inspect the inner tyre edges for feathering, which would indicate tracking or bush wear not yet severe enough to trigger an MOT advisory. Structurally, the C4 Cactus uses a plastic body panel design that resists cosmetic rust, but the underlying chassis and subframes are still susceptible to corrosion, particularly around the rear suspension mounting points and inner wheel arches. A thorough underside inspection is advisable, focusing on any signs of surface rust or previous underseal deterioration. The clean recent MOT is encouraging, but it does not substitute for a physical examination of these age-related wear points.
