2018 Citroen C1 1.2L Petrol · LS18 TSU

The latest MOT test result on 2026-04-15 shows the vehicle failed due to a critically compromised front brake disc, which is classified as a dangerous failure under 1.1.14(a)(ii), indicating the disc’s structural integrity is severely compromised to the point of posing a serious risk to braking performance. While the preceding MOT on 2025-04-16 was passed, the recurring advisories and failures—particularly the front brake system issues—suggest a pattern of wear and potential underlying mechanical degradation that has not been adequately addressed. The 2023 failure, which also highlighted brake pads worn below the legal minimum thickness of 1.5 mm, underscores a persistent and unresolved problem with the braking assembly, warranting immediate attention. The recent advisories on anti-roll bar linkage components and tyre wear further indicate that the suspension and tyre systems are also experiencing wear that requires monitoring. The recorded mileage of 71,184 miles for a 2018 C1 represents a moderate annual usage rate of approximately 8,898 miles per year, which is consistent with typical usage for its age. This level of mileage, while not exceptionally high, does not necessarily imply excessive wear if the vehicle has been maintained reasonably well, but the history suggests some components have been subjected to prolonged stress. The absence of significant mileage gaps could imply either consistent use or prolonged periods of inactivity, which may have contributed to issues like standing corrosion or fluid degradation in certain systems. However, the brake system failures and advisories on anti-roll bar components indicate that wear has been progressive, likely accelerated by regular operation rather than just time alone. Given the vehicle’s history, the prospective buyer should prioritise a thorough inspection of the front brake assembly, focusing on the condition of the brake discs, pads, and calipers. The critical failure of the front brake discs in 2026 indicates they may have already reached a point where they are no longer safe to use, and the buyer should expect to replace them immediately. During a test drive, listen for uneven brake pedal travel, a spongy or vibrating feel, or signs of pulsation, which could indicate warped discs or binding calipers. Additionally, check for any brake fluid leaks around the calipers or master cylinder, as this could signal hydraulic system issues. The advisories on anti-roll bar linkage pins and bushes suggest that these components are wearing out, which may lead to excessive movement or clunks in the suspension when driving over bumps. Inspect the linkage for excessive play or corrosion, and listen for clunking noises when the vehicle is driven over rough roads. Beyond the immediate concerns, the buyer should also examine the tyre condition, particularly the inner edges of the front tyres, which have been noted as worn close to the legal limit in multiple MOTs. Uneven wear patterns, such as feathering or cupping, may indicate suspension or alignment issues that require attention. Check the tyre sidewall for signs of cracking or perishing, which can weaken the tyre structure and reduce its lifespan, especially if the vehicle has been in storage for extended periods. The front windscreen damage recorded in previous MOTs is not a safety concern but should be repaired to maintain visibility. Additionally, given the vehicle’s age and the recorded low oil level in 2024, verify the engine oil level and condition, ensuring it is topped up to the correct level and that the oil is fresh. The 12V battery should also be tested for charge retention, as prolonged standing can lead to corrosion or failure in the electrical system. Finally, since the vehicle is nearing its eighth year, consider scheduling a comprehensive service check, including fluid top-ups (brake, coolant, power steering, and transmission), and inspecting the suspension components for signs of wear or damage beyond what the MOT records indicate.
