2016 Citroen C1 1.2L Petrol · SO16 ECZ

The most recent DVSA MOT test on 30 July 2026 resulted in a pass, although it should be noted that on the same date an earlier presentation of the vehicle failed on a Major defect for an inoperative horn, a straightforward rectification but a reminder to confirm the horn currently operates correctly on first press. Beneath this pass sits a notable cluster of advisories affecting the front suspension and brake system, indicating that while the car remains legally roadworthy, several mechanical components are displaying age-related degradation that warrants close attention. Reviewing the broader pattern across 2024, 2025, and 2026, the maintenance trajectory is clearly one of gradual deterioration rather than stability; items such as the front sub-frame corrosion and rear brake pipe corrosion have appeared consistently across three consecutive tests, while new advisories concerning the lower suspension arm ball joint, front anti-roll bar linkages, and rear brake fluctuation have emerged in the latest examination. The presence of a Major failure for excessively fluctuating rear brakes in 2025, which then reverted to advisory status in 2026, suggests an interim brake repair or adjustment, though the underlying issue has not been fully resolved. With a recorded mileage of 49,960 miles over an approximate ten-year lifespan, this CITROEN C1 has covered only around 4,996 miles annually, a figure well below the national average for a vehicle of this age and segment. Such low usage can be interpreted in two ways: either the car has been driven gently with light wear on major drivetrain components, or it has experienced extended periods of standing, which carries its own set of mechanical consequences. Standing vehicles are particularly prone to brake disc corrosion, binding calipers, and deterioration of flexible components such as coolant hoses, drive belts, and tyre sidewalls due to age rather than wear. The annual test history reflects this ambiguity, as several advisories relate to corrosion on the sub-frame and brake pipes, conditions accelerated by limited use, moisture ingress, and infrequent operation. For any prospective buyer, the recurring advisories demand a focused physical inspection and a discerning test drive. The front suspension components should be examined for any worsening play in the lower arm ball joint, corrosion progression on the suspension arms and sub-frame, and wear in the anti-roll bar linkage bushes; during a road test, listen for clonking or knocking noises over speed humps and uneven surfaces, and feel for vagueness or imprecise steering response. The brake system requires particular scrutiny, given the persistent rear brake pipe corrosion, the fluctuating rear brake performance, and the general age of the braking components; on test, expect to feel any pulling to one side, a spongy or inconsistent pedal, or brake shudder under firm application, and inspect the discs for lipping, surface rust, and pad material remaining. Given the sub-frame advisories, a thorough examination on a ramp for any structural cracking or perforation around mounting points would be prudent before committing to purchase. Beyond the specific advisories, the low annual mileage profile means several time-based service items deserve verification regardless of odometer reading. Tyres should be checked closely for sidewall perishing and cracking due to age, even if the tread depth appears adequate, as rubber degrades chemically over a decade regardless of mileage. The 12V battery is likely original or near-original and may be approaching the end of its reliable service life, so a load test or voltage check is advisable. Coolant, brake fluid, and engine oil should be confirmed as recently refreshed, as these fluids degrade with calendar age and can compromise cooling, braking, and lubrication if left unchanged. Finally, inspect the exhaust system for rust, check the operation of all interior and exterior electrical items including the previously failed horn, and verify that the service book contains stamps at appropriate intervals to confirm the vehicle has not only been used sparingly but also properly maintained during its life on the road.
