2016 Citroen C1 1.2L Petrol · ST04 DFY

The most recent DVSA MOT test on 4 July 2026 resulted in a pass, but it was accompanied by four advisory items that collectively signal the vehicle is entering a phase of accumulated wear requiring closer inspection. The advisories cover front sub-frame corrosion described as not seriously weakened, front brake disc wear with pitting and scoring, thinning front brake pads, and rear tyres noted as both worn close to the legal limit at 3mm and showing damage, cracking, or perishing. Comparing this with the prior two tests in July 2025 and June 2024, which were passed with no defects recorded, and the earlier passes in 2022 and 2021, there is a discernible downward trend in the condition being presented for test. The June 2023 test also produced a failure for a dangerous inner brake pad and a major headlamp defect, confirming that braking and lighting components have been a recurring concern. Overall the maintenance trajectory appears to be worsening rather than stable, which is consistent with the vehicle reaching ten years of age. The recorded mileage of 79,116 miles over a ten-year life equates to an annual average of approximately 7,912 miles, which is broadly typical for a small city-oriented hatchback of this age. There are no extended gaps in the MOT record that would suggest prolonged standing, and the relatively consistent year-on-year test entries indicate regular use. This is mechanically favourable in some respects, as accumulated mileage tends to keep lubricants circulating, prevents brake discs from corroding excessively from disuse, and maintains battery charge. However, the mileage itself is now firmly in the upper bracket for a 2016 C1, meaning that consumable wear items such as brake discs, pads, tyres, suspension bushes, coil springs, and exhaust components will be approaching the latter portion of their service life. Continued annual mileage at the same rate will likely accelerate replacement intervals for these parts. In terms of specific buyer guidance, the most pressing items relate to the braking system, given the June 2023 dangerous failure for an offside front inner brake pad and the recent advisory noting worn and pitted front brake discs alongside thinning pads. On a test drive, any brake shudder felt through the pedal or steering wheel would confirm the disc pitting noted on test, while a squeal or grinding noise under light or moderate pedal pressure would indicate the pads have worn further since the advisory was issued. The front brake discs should be physically inspected for lip measurement and surface scoring, and a realistic expectation is that a reconditioned pair of front discs and a new set of pads will be required imminently. The front sub-frame corrosion advisory should also be examined with the vehicle on a ramp to confirm the extent and location of the corrosion, ensuring it remains confined to surface oxidation rather than progressing into structural weakening around mounting points, steering racks, or suspension pick-ups. The rear tyre advisory noting 3mm tread depth and sidewall cracking or perishing effectively renders them due for replacement, and when fitting new tyres the front pair should also be considered given the age-related perishing risk on a ten-year-old vehicle. On a physical inspection, all four tyres should be examined for sidewall cracking, particularly in the flex zone between tread and rim, as rubber degradation with age can occur independently of mileage. The C1 also benefits from a check of the timing chain or belt service interval depending on engine variant, coolant and brake fluid age-related replacement regardless of mileage, and verification that the 12V battery holds charge under load as a weak battery is common on short-journey urban cars. A thorough test drive should include listening for suspension clonks over uneven roads, confirming the headlamp dipped beam functions correctly following the 2023 failure, and ensuring the clutch and gearbox operate smoothly, as these are known wear items on higher-mileage C1 examples.
