2017 Citroen C3 1.2L Petrol · CF66 AYY

A pattern of tyre degradation and brake irregularities defines the mechanical story of this 2017 Citroen C3, culminating in a recent MOT that exposed two dangerous tyre failures alongside a flagged front brake fluctuation. Across eight recorded tests, six passed cleanly with no advisories between 2020 and 2024, suggesting a stable roadworthiness baseline for most of its life. However, the 2025 test introduced advisory notices for cracking and perishing on both rear tyres and a cut on the nearside front tyre, and by 9 January 2026 the rear tyres had deteriorated to the point of dangerous structural failure, with a major defect also raised against the front service brake for excessive fluctuation and an advisory noting front brake disc wear. This escalation from clean passes to dangerous failures within a twelve-month window is a notable concern, particularly given that the tyre issues were forewarned by the 2025 advisories. With a recorded mileage of 23,345 miles over approximately nine years, the vehicle has accumulated around 2,594 miles annually, which is markedly low for its age and segment. Such restrained usage typically places less mechanical demand on the engine, clutch and drivetrain, but it does increase the risk of component degradation from standing, particularly in the braking system, suspension bushes, brake calipers, brake fluid, and tyres. The progression of the tyre condition from minor cracking advisories in 2025 to dangerous structural tears in 2026 is consistent with rubber ageing from limited use rather than wear from mileage, and the brake disc wear and fluctuating service brake finding may similarly reflect seized or binding calipers, corroded brake pipes, or moisture-compromised fluid typical of low-mileage vehicles. For a prospective buyer, the priority inspection areas should be the braking system and the tyres, as these are the only components to have generated advisories or failures across the recorded history. On a test drive, listen for any grinding, squealing, or pulsation through the brake pedal, which could indicate the binding caliper or warped discs suggested by the fluctuating brake and disc wear advisory. Check that the car pulls up straight under heavy braking and that the pedal feels firm rather than spongy. Inspect all four tyres closely for sidewall cracking, bulges, or any signs of structural separation, particularly on the rear axle where the dangerous tears were recorded, and consider whether a full set of new tyres will be required regardless of legal tread depth. Beyond the braking and tyre concerns, a low-mileage vehicle of this age warrants a thorough check of all rubber components including suspension bushes, anti-roll bar links, and engine mountings, as these can deteriorate with prolonged standing even when overall mileage is modest. Listen for clonks or knocks over speed humps and uneven road surfaces, and verify that the handbrake holds the vehicle on an incline, as handbrake cables and mechanisms can seize when infrequently used.
