2015 Citroen C3 1.2L Petrol · LB15 CWC

The 2015 Citroen C3 presents a mechanical picture dominated by recurring minor failures rather than catastrophic breakdowns, with three separate failed MOT tests between 2024 and 2025 each returning the same core issues. The pattern centres on light oil contamination in the nearside rear shock absorbers alongside inconsistent front headlamp aiming—both nearside components failed twice in quick succession while the rear shock problem persisted across multiple assessments. Despite passing the most recent test on 2026-04-27, the lingering rear lens advisory and repeated headlamp misalignment suggest underlying work that has not yet been fully resolved, leaving potential safety implications around visibility and suspension geometry even though the vehicle cleared its final examination. The mileage record of 22,155 miles accumulated over approximately eleven years translates to roughly 2,014 miles per year, which is notably lower than typical usage for a vehicle of this make and model. The absence of a MOT test between May 2021 and May 2023 represents a fourteen-month period during which the car was either stored or driven extremely sparingly, as the subsequent tests showed consistent minor defects rather than complete failures. After clearing the 2023 and 2022 passes, the car reappeared on the fail list in early 2024, followed by another failure later that same year before finally passing again in mid-2025. While the current figure appears modest for an eleven-year-old car, the irregular spacing of tests combined with the persistence of certain advisories indicates that the vehicle's usage profile has been highly variable, with long intervals of minimal movement punctuated by brief periods of active driving. Focused inspection should concentrate on the rear shock absorber assembly where light oil misting has recurred across four consecutive MOT reports, potentially indicating gradual internal seal degradation or fluid leakage that manifests as subtle damping changes under load. The nearside headlamp assemblies require verification of their mounting alignment—past failures included both high and low aims, suggesting the adjustment mechanism may have shifted or the lenses themselves have developed slight deformation over time. A test drive should pay particular attention to how the suspension responds to bumps through the rear axle, listening for any knocking or hopping noises that might signal ongoing shock absorber wear, and checking whether the front headlights maintain correct vertical alignment at various speeds to ensure proper beam distribution. Given the persistent rear lens advisory, also inspect the rear lighting assembly for any physical damage or fogging that could affect night-time legibility. These specific areas represent the primary mechanical risks that remain despite the vehicle having passed its last examination.
