2015 Citroen C3 1.2L Petrol · YA64 MXG

Recurring structural corrosion on the rear sub-frame represents the primary mechanical concern for this vehicle, as it has been flagged as an advisory in three consecutive MOT tests dating back to February 2024. While the most recent test on 24 February 2026 resulted in a pass, the persistent mention of corrosion under item 5.3.3 (b) (i) indicates a continuing condition that has not been rectified. This pattern of advisories, alongside a previous failure in February 2025 regarding a split offside drive shaft constant velocity boot, suggests that while the vehicle remains roadworthy, certain structural and drivetrain components are subject to progressive wear or environmental degradation. The recorded mileage of 41,387 miles over an eleven-year period reflects a low annual usage rate of approximately 3,762 miles. Such a low accumulation of mileage can often result in components being subjected to less frequent mechanical cycling, which may contribute to the observed perishing of tyres noted in the February 2024 test. Mechanically, this usage pattern means that while high-wear items like engine internals may show less mileage-related fatigue, rubber components such as suspension bushes, seals, and tyre sidewalls are more susceptible to age-related degradation and cracking due to extended periods of inactivity or limited movement. A prospective buyer should pay close attention to the condition of the rear sub-frame during a physical inspection, looking for signs of surface rust transitioning into deeper pitting or structural scaling. Because the corrosion has been noted repeatedly, it is essential to monitor the vehicle during a test drive for any changes in handling or stability. Listen for any knocking, clunking, or rhythmic thudding from the rear of the car when traversing uneven surfaces or speed bumps, as these could indicate that the sub-frame corrosion is beginning to affect the integrity of the mounting points or the suspension geometry. Additionally, the history of a split drive shaft CV boot and previous exhaust mounting issues warrants a thorough check of the drivetrain and exhaust system. During the test drive, pay close attention to any clicking or clicking sounds when turning the steering wheel at low speeds, which could signal further issues with the drive shaft joints. It is also advisable to check for excessive vibration through the floor or seat while accelerating, and to listen for any rattling or loose sounds from the exhaust system, ensuring that the previous failures regarding exhaust security have been fully addressed.
