2003 CITROEN C31.6L Petrol

The Citroën C3’s most recent MOT test on 17 March 2026—just four months ago—resulted in a failure, though no specific defects were recorded. This marks the first failure since June 2022, when the vehicle also failed twice within days, yet passed both subsequent tests without failings. The absence of advisories or defects across all tests suggests the tester did not identify any major mechanical or structural issues, but the repeated failure in 2022 and the latest one in 2026 indicate either a procedural oversight or a persistent minor issue that consistently falls below the MOT threshold. The lack of advisories also implies that while the vehicle may have passed minor wear-and-tear checks, there could be hidden concerns in areas not routinely scrutinised, such as suspension integrity or exhaust integrity. The recorded mileage of 86,122 miles over 23 years equates to an average of approximately 3,744 miles annually, which is unusually low for a vehicle of this age. This suggests the car has spent extended periods either stationary or lightly used. The gap between tests—particularly the two failures in June 2022 at 84,241 miles—implies the vehicle may have been out of service for some time before retesting. The most recent test in March 2026, just 1,362 miles after the November 2024 pass, further supports this pattern, as the low mileage accumulation between tests reduces wear on critical components like brakes, suspension, and engine systems. However, this also raises questions about whether the vehicle has been stored improperly, potentially accelerating corrosion or fluid degradation. Given the lack of recorded defects, a buyer should prioritise an independent inspection of high-wear areas that often fail silently. Focus on the suspension—particularly the condition of coil springs, bushes, and shock absorbers—since these components degrade gradually and may not trigger MOT advisories until they are severely compromised. The brakes, despite no recorded failures, warrant close examination for uneven wear, binding calipers, or corrosion on the rear discs, which could explain the repeated failures. Structural integrity is another concern; inspect the underbody for corrosion around the sills, wheel arches, and subframe, as prolonged stationary periods can accelerate rust. Additionally, verify the integrity of the exhaust system, as leaks or damage may not always be visible but can affect emissions and structural stability. Given the car’s age, fluid levels—brake, power steering, and coolant—should be checked for degradation or contamination, as these are not routinely tested in MOTs.
