2011 Citroen C1 1.0L Petrol · PE61 AAF

The most recent MOT, carried out on 15 October 2025, was passed but recorded advisories concerning corrosion on both rear brake pipes. Over the previous five years the vehicle has shown a pattern of recurring brake‑pipe corrosion, progressive wear on front suspension arm pins and bushes, and a serious brake failure in September 2023 that required remedial work before the next pass. While the car has managed to pass the two latest tests, the persistence of the same corrosion advisories and the appearance of new suspension and tyre observations suggest that the overall maintenance trend is not improving but remaining marginally stable after a significant corrective intervention in 2023. At 78 614 miles on a 2011 model the average annual mileage works out at roughly 5 200 mi, well below the typical 10‑12 000 mi per year for a vehicle of this age. Such low utilisation often points to periods of prolonged storage, which can accelerate age‑related degradation such as rubber perishing, battery sulfation and corrosion of steel components, even though the mechanical wear from distance travelled is modest. The modest mileage does not, however, eliminate the need to consider the cumulative effects of fifteen years of exposure to the elements and the occasional high‑load events that may have contributed to the brake and suspension issues noted in the MOT records. A prospective buyer should give the rear brake pipes a thorough visual inspection for rust, pitting or flaking, and verify that the surrounding greased area is not masking a leak. The brake fluid should be tested for moisture content and topped up or replaced if it is near the minimum mark; a fresh fluid change will also help reveal any hidden corrosion in the system. The parking brake must be checked for firm engagement on both sides, and a road test should include a firm, progressive pedal feel with no pulsation, which would indicate uneven pad wear or disc distortion. Front suspension arm pins and bushes should be examined for excessive play by applying a firm push‑pull on the wheel at the 12 and 6 o’clock positions; any clunk or noticeable movement would confirm the advisory warnings and may require replacement. Likewise, the rear suspension should be inspected for rusted or cracked components, especially where the chassis meets the sub‑frame, as corrosion can compromise structural integrity. Tyre condition warrants particular attention: the 2023 advisory about slight damage and perishing suggests the sidewalls may be ageing, so look for cracks, dry rot or softened rubber, especially on the outer edges. Verify that tread depth is uniform and that there is no cupping or feather‑edge wear that could hint at suspension misalignment. Because the car has likely spent time stationary, the 12‑volt battery should be load‑tested and the terminals cleaned of any corrosion. Finally, check that routine fluids—engine oil, coolant, and power‑steering fluid—have been changed at appropriate intervals, and that the service book contains stamps confirming these maintenance actions. Addressing these points will give a clear picture of the car’s current roadworthiness and the likely cost of bringing it to a fully reliable condition.
