2009 Citroen C1 1.0L Petrol · NG09 LCJ

Significant structural corrosion and recurring suspension and braking issues define the mechanical history of this Citroen C1, with the most recent test on 1 July 2026 showing a pass despite ongoing advisories for a binding nearside rear service brake and a perishing offside front tyre. The vehicle has demonstrated a pattern of serious structural failures, most notably in June 2026 when it failed on multiple major defects relating to inadequate repairs and significant corrosion to the inner and outer sills on both the offside front and offside rear. This follows a dangerous failure in June 2025 regarding anti-roll bar linkage pins and bushes, alongside major corrosion to the inner integral body structure. The trend indicates a vehicle struggling with advanced age-related degradation of its chassis and structural integrity. The recorded mileage of 152,175 miles over approximately 17 years represents an average annual accumulation of roughly 8,951 miles, which is consistent with typical usage for a vehicle of this age. While this mileage does not suggest excessive high-speed motorway running, the cumulative distance combined with the recorded age is clearly reflected in the recurring failures of consumable and structural components. The frequency of the MOT tests suggests regular annual inspections, which has allowed for the identification of worsening corrosion in the sills, subframe, and suspension mounting areas over several years. Prospective buyers should pay close attention to the structural condition of the sills and floorpan, given the recent major failures for corrosion and inadequate repairs. On a test drive, listen for any creaking or knocking sounds from the suspension, particularly when navigating uneven surfaces, as the anti-roll bar linkages and bushes have been flagged repeatedly for wear and dangerous detachment. Additionally, monitor the braking performance for any pulling to one side or uneven pedal feel, which could indicate the binding nearside rear brake mentioned in the latest advisory. The history of corroded brake pipes and subframe issues necessitates a thorough visual inspection of the underside for any signs of weeping fluid or advanced oxidation. Check the condition of the tyres, specifically looking for sidewall cracking or perishing on the offside front, as this has been a consistent advisory since at least 2025. Any signs of recent welding or structural patching should be scrutinised to ensure that the repairs to the sills and floorpan meet required standards and have effectively addressed the structural rigidity concerns noted in the 2026 failure.
