2015 Citroen C1 1.0L Petrol · CA15 XGR

Significant brake system deterioration and emerging structural corrosion represent the primary mechanical risks identified in the recent history of this Citroen C1. While the vehicle passed its most recent test on 09 December 2025, this followed a dangerous failure on the same date due to seriously weakened front brake discs, brake pads measuring less than 1.5mm, and an excessively twisted front brake hose. The transition from a dangerous failure to a pass within the same testing period indicates that critical braking components were replaced or repaired, yet the record shows a pattern of recurring advisories regarding brake disc condition dating back to 2019. Furthermore, the latest inspection introduced advisories for rear axle corrosion and worn anti-roll bar linkage pins or bushes on both the nearside and offside fronts, suggesting that while the immediate braking hazards were addressed, other wear items and structural oxidation are now coming to the fore. The vehicle has covered 64,472 miles over its eleven-year lifespan, which equates to an average annual accumulation of approximately 5,861 miles. This represents a lower-than-average usage pattern for a vehicle of this age. From a mechanical perspective, such low annual mileage can result in less frequent replacement of consumables and may contribute to the observed issues, such as the perished tyre recorded in 2019 or the pitting and scoring of brake discs. While lower mileage generally implies less wear on the drivetrain and engine, it can also mean that components like suspension bushes and brake components are subject to more environmental degradation and oxidation due to longer periods of inactivity or lower operating temperatures rather than high-frequency mechanical use. Prospective buyers should pay close attention to the braking system and suspension during a test drive to ensure the recent repairs have fully rectified the previous dangerous defects. Listen for any rhythmic clicking or knocking sounds when driving over uneven surfaces or speed bumps, which could indicate that the advised anti-roll bar linkage pins or bushes have progressed from minor wear to significant play. A firm, consistent brake pedal is essential; any sponginess, pulsation, or judder through the pedal may suggest issues with the newly fitted discs or remaining brake hose integrity. Given the advisory regarding the twisted brake hose, it is vital to ensure the steering feels smooth and that there is no sudden change in pedal feel when turning the wheel to full lock. The advisory concerning rear axle corrosion requires careful scrutiny of the vehicle's underside. While the record states the corrosion is not currently seriously weakened, the presence of oxidation on a structural component is a progressive issue. A physical inspection of the rear axle and subframe area is recommended to assess the depth of the corrosion. Additionally, the advisory regarding undercovers suggests that some protective shielding may be loose or damaged, which could allow road salt and moisture easier access to the chassis and suspension components. Any signs of fluid weeping from the suspension or steering components should be noted, as the combination of low mileage and existing corrosion advisories necessitates a thorough check of the vehicle's structural integrity.
