2018 Citroen C3 Aircross 1.2L Petrol · SM67 EYO

The C3 Aircross presents a mixed maintenance picture. The most recent MOT activity occurred in January 2026 at 27,906 miles, where the vehicle failed on the same day it subsequently passed, indicating the faults were rectified promptly. However, the pattern across the full record reveals a worsening trend in mechanical attention. The December 2023 test at 21,107 miles was entirely clean, but by December 2024 at 24,512 miles, the tester flagged an exhaust Lambda reading outside specified limits and a worn offside front tyre. The January 2026 failure added a split nearside front CV joint boot and insufficient windscreen washer fluid to the recurring worn front brake disc advisory. The CV boot failure is particularly concerning, as a split boot allows dirt ingress that accelerates joint wear and can lead to costly drive shaft replacement if left unaddressed. The mileage profile is notably low for an eight-year-old vehicle. At 27,906 miles, the annual average sits at roughly 3,488 miles per year, well below the typical UK average of 8,000 to 12,000 miles. The recorded intervals show 3,405 miles covered between December 2023 and December 2024, then 3,394 miles between December 2024 and January 2026, a remarkably consistent and gentle usage pattern. This low mileage suggests predominantly short urban trips, which can be harder on components than steady motorway driving. Short runs prevent the engine and exhaust reaching optimal operating temperature, increasing the risk of carbon build-up, DPF issues, and moisture-related corrosion in the exhaust system, which may explain the Lambda reading failure in December 2024. A buyer should inspect the front brake discs closely, as the worn and pitted condition noted in January 2026 suggests the vehicle has been standing for extended periods or driven gently enough to cause disc surface corrosion rather than even pad wear. The nearside front CV joint boot has already been replaced or repaired following the January 2026 failure, but the joint itself should be checked for play or clicking under load, as contamination may have already occurred before the repair. The exhaust Lambda fault from December 2024 warrants a check of the catalytic converter and oxygen sensors, particularly given the short-trip usage pattern that can degrade emissions components prematurely. Tyre condition also demands attention. The offside front tyre worn to the legal limit in December 2024 suggests uneven wear patterns, possibly from misaligned tracking or underinflation, and the buyer should examine all four tyres for similar edge wear. The low annual mileage and January 2026 test date mean the current MOT certificate is valid until January 2027, but the cluster of advisories and the split CV boot indicate this vehicle has not been maintained to a high standard despite its low mileage. A pre-purchase inspection focusing on the front drivetrain, braking system, and exhaust emissions is strongly recommended.
