2016 Citroen C1 1.2L Petrol · AY66 XFP

The 2016 Citroen C1 presented a concerning trajectory of mechanical degradation culminating in a failed MOT on 2026-07-07 where both front brake discs were found significantly worn and brake pads measured below the critical 1.5mm threshold while nearside front anti-roll bar ball joint dust covers suffered severe deterioration. This failure represents a marked deterioration compared to the prior four years of mostly advisory-only results from 2023 through 2025, when the same components—anti-roll bar bushings and front tyres—recurred as persistent minor issues that never escalated to immediate danger. The single failed test indicates that earlier warnings were either ignored or addressed incompletely, allowing the underlying wear to progress to a point where safety standards could no longer be met. At 64,500 miles on a ten-year-old vehicle, the average annual mileage of approximately 6,450 miles falls within the expected range for its age, suggesting the car has been driven regularly rather than stored or underutilised. However, the gap between the 2025-07-04 pass and the 2026-07-07 fail spans nearly two years of accumulated wear, with the critical brake and suspension failures emerging suddenly rather than gradually. This sudden acceleration in deterioration contrasts with the steady advisory pattern seen previously and suggests either a change in driving conditions, lack of timely maintenance, or progressive material fatigue that was not caught during earlier inspections. The nearside front brake system presents the most urgent concern, with both discs showing significant and obvious wear and brake pads measuring less than 1.5mm—a condition classified as dangerous because it compromises stopping performance. On a test drive, expect noticeable pulling or vibration when approaching speed bumps, and the brakes may feel spongy or show reduced modulation due to thin pads. The anti-roll bar ball joint dust covers on both sides are also severely degraded; you should feel increased play in the front suspension when turning corners and notice a harsher, more unpredictable ride quality. These symptoms are direct consequences of the worn components and should be inspected thoroughly before considering purchase. The rear tyres continue to show signs of damage including cracking and pitting, particularly on the nearside rear and offside front positions, which may indicate uneven wear patterns or underlying structural issues. Given the proximity of the failing front brakes and compromised suspension geometry, the combined effect of poor braking response and erratic handling could pose a serious safety risk during city driving or on uneven roads. A pre-purchase inspection should prioritise a detailed brake overhaul, full anti-roll bar assembly replacement, and a thorough subframe and suspension assessment to ensure the vehicle meets current safety requirements before committing to ownership.
