2010 Citroen C1 1.0L Petrol · FD10 YCT

The most recent DVSA examination on 27 May 2026 resulted in a pass, though an advisory was issued for an offside rear service brake binding slightly but not excessively, suggesting early stage caliper slider or mechanism wear that warrants monitoring at the next test. Looking at the broader four year history, the vehicle has demonstrated a pattern of pass and fail oscillation rather than a stable improvement, with two outright failures on parking brake efficiency and front brake binding in 2024 and 2023, alongside a further failure in 2022 for headlamp beam aim. However, the recurring brake related advisories for rear brake pipe corrosion and the 2025 advisories for seat belt anchorage and general underbody corrosion indicate a vehicle that is progressively accumulating age related structural and brake system degradation, which is consistent with its sixteen year service life. The trend is therefore one of stable pass results but with an underlying picture of worsening advisories related to corrosion and brake component wear that should not be dismissed. With a recorded mileage of 87,169 miles over sixteen years, this Citroen C1 averages roughly 5,448 miles annually, which is markedly low and suggests extended periods of standing combined with modest use. Such low annual mileage often points to a second car, urban runabout, or garage stored vehicle, and while it reduces wear on major drivetrain items like the engine and clutch, it accelerates calendar based degradation of fluids, rubber components, brake discs and battery health. The relatively narrow annual accumulation also means that MOT frequency reveals less about high mile wear and more about deterioration through inactivity and age, which aligns well with the corrosion and perishing advisories documented over the last three tests. Given the recurring brake pipe corrosion advisories first noted in 2022 and reappearing annually through to 2025, a prospective buyer should arrange a thorough underbody inspection paying particular attention to the rear brake lines, looking for advanced surface rust, flaking, or any weeping of brake fluid that would indicate replacement is imminent. The 2025 advisories concerning corroded seat belt anchorage outer sills and integral body structure across the underside suggest corrosion is becoming widespread, so a close visual inspection of the sills, chassis outriggers, floor pans, and suspension mounting points is essential, ideally conducted by placing it on a ramp rather than just a jack. Any structural integrity concerns should prompt a professional assessment, as corrosion repairs on older C1s can quickly exceed the residual value of the car. Additionally, the 2024 exhaust minor leak between centre and rear sections should be rechecked, and the offside rear tyre damage and perishing flagged at that time demands a fresh inspection of all four tyres for sidewall cracking given the age related rubber degradation typical of low mileage vehicles. On a test drive, particular attention should be paid to the braking system, as the binding rear brake advisory from the latest test, combined with the historical front brake binding failures in 2024, could manifest as uneven braking, a pulling sensation to one side under heavy pedal application, or a tendency for the car to creep forward on level ground when the handbrake is engaged, the latter linking directly to the parking brake efficiency failures of 2023 and 2024. Listen for any grinding, squealing, or clonking from the front brakes, which would confirm the pitted front disc advisory recorded at the 2024 failure, and be alert for brake pedal pulsation indicating disc runout. Equally important for a low mileage sixteen year old car is a check of the twelve volt battery state of health, as standing periods are highly corrosive to battery life, and verification that the brake fluid, coolant, and engine oil have been refreshed within their calendar service intervals rather than purely mileage based schedules. Confirming a complete service history with documentation of these time based fluid changes, together with evidence that the underbody has received rust prevention treatment, will substantially de risk the purchase and provide confidence that the underlying corrosion advisories are being actively managed.
