2012 Citroen DS3 1.6L Petrol · YA12 UOS

A consistent passing record is tempered by a trend of emerging mechanical wear, specifically regarding fluid leaks and suspension degradation. The latest test on 1 May 2026 confirms a pass, but the reappearance of an oil leak and the introduction of play in the offside front lower suspension arm ball joint suggest a vehicle entering a phase of age-related component fatigue. The recurring mention of engine covers and undertrays obscuring components indicates that full visual inspections of the engine bay may be hindered during testing, potentially masking the extent of leaks. With 69,302 miles recorded over 14 years, the vehicle has averaged approximately 4,950 miles per year. This low annual accumulation suggests the car has not been subjected to heavy motorway wear, but it may be more prone to issues associated with infrequent use. The steady mileage progression across the MOT history indicates consistent, albeit light, usage rather than long periods of dormancy, though the low mileage often correlates with the pitting of brake discs observed in the 2023 records. Attention must be paid to the offside front suspension and the engine sealing integrity. During a test drive, listen for knocking or clicking sounds when traversing uneven road surfaces or during low-speed manoeuvring, which would indicate the ball joint play has progressed. The persistent oil leak, flagged in both 2024 and 2026, requires a physical inspection of the sump and cylinder head area to determine the source and ensure it is not impacting other components. The history of pitted and scored brake discs in 2023, combined with a corroded rear exhaust box in 2024, points to a vulnerability to surface corrosion. Check for any pedal judder or pulsation during braking, which would suggest the discs were not replaced and remain scored. Additionally, listen for an increased exhaust note or a rasping sound from the rear of the vehicle to verify if the previously noted exhaust leak has been addressed or has worsened.
