2012 Citroen C1 1.0L Petrol · SP08 PUG

The 2012 Citroen C1 presents a pattern of recurring brake system failures spanning four years, beginning with severely worn inner front and rear brake discs and escalating to corroded brake pipe assemblies before achieving a clean MOT result on 2025-11-11. Two earlier failures in 2020 and 2021 involved oil leaks and inner brake disc wear respectively, followed by a series of passes and fails between 2022 and 2024 where the same rear brake pipe corrosion and front disc wear recurred before the final clearance. The progression from multiple major failures to a straightforward pass indicates a gradual resolution of critical safety components though the earlier breakdowns demonstrate that underlying issues persisted across successive examinations. With 105,204 recorded miles on a fourteen-year-old vehicle, the annual accumulation averages approximately 7,515 miles—a rate consistent with moderate everyday use rather than intensive commercial driving. The clustering of three successive failing exams between September 2024 and December 2025 suggests periods of heavier use punctuated by intervals of lower activity, which aligns with the high total mileage having accelerated general wear on suspension linkages, subframe fasteners, and drivetrain components. While the current MOT does not flag new issues, the substantial odometer reading combined with the brake-related history warrants attention to whether routine inspections have addressed cumulative fatigue in non-brake areas as well. The most urgent mechanical concerns for a test drive centre on the nearside and offside rear brake pipes, which have repeatedly failed due to corrosion and grease buildup; listen for distinct knocking sounds when travelling over bumps and visually inspect for wet spots or oily residue around the rear wheel arches during a slow-speed approach. Both front and rear inner brake discs are reported as significantly and obviously worn across multiple MOT records, manifesting as chassis vibration upon braking and a metallic grinding or squeal when the pads engage even lightly. These conditions typically produce a pulsating ride quality and may require immediate replacement to restore normal stopping performance and prevent further component degradation. Headlamp beam projection errors were recorded in 2024-09-25 as a major failure, pointing to misalignment that can cause dazzling effects or insufficient illumination in certain directions—verify the aim by observing the light spread at low and high beam settings. An oil leak identified in 2021 and reiterated in 2024 suggests possible seal deterioration in the undercarriage, which could allow lubricant to reach the interior carpet or floorboards and compromise electrical insulation if not repaired promptly. Combining these findings, a pre-purchase inspection should confirm that the brake pipes have been properly cleaned and resealed, the brake discs are replaced, the headlamps are recalibrated, and the undercarriage oil path is inspected for fresh leakage.
