2017 MINI Cooper 1.5L Petrol · T6 CSD

The most recent MOT test on 2026-01-06 resulted in a failure due to a major defect with the near-side rear tyre exhibiting a deep cut reaching the ply or cords, alongside an advisory for front brake pads wearing thin across all four quadrants. While the preceding MOTs from 2025 and 2024 were clean, the 2026 test reveals a concerning escalation in tyre-related issues, particularly the progression of a critical tyre defect that now warrants immediate attention. The front brake advisories—thin pads and worn discs—have persisted across multiple tests, indicating a pattern of gradual wear that could compromise braking efficiency if left unaddressed. The presence of wheel distortion advisories in several tests suggests potential underlying structural or mounting issues that may require further inspection, especially if the vehicle exhibits uneven tyre wear or excessive play in wheel alignment during a test drive. The vehicle’s recorded mileage of 26,694 miles at the time of assessment represents a relatively low annual usage rate of approximately 2,966 miles per year, which is unusually low for a nine-year-old car. Such low mileage often correlates with periods of prolonged inactivity, where components like brakes, tyres, and suspension may degrade more rapidly due to standing corrosion or fluid degradation over time. The absence of higher mileage accumulation suggests that the vehicle has not been subjected to heavy or frequent use, which could mask underlying wear until a test drive reveals subtle but critical issues, such as binding calipers from corrosion or uneven tyre wear patterns indicative of suspension misalignment. The low mileage profile also raises questions about whether the vehicle has been stored in a controlled environment, as damp or extreme conditions can accelerate corrosion in brake systems, suspension components, and the vehicle’s structural integrity. Given the recent MOT failure and recurring advisories, the buyer should prioritise a thorough inspection of the tyres, brakes, and wheels. The deep cut in the near-side rear tyre is a major defect requiring immediate replacement, as it poses a safety risk and could lead to a catastrophic failure. During a test drive, listen for unusual noises from the rear axle or wheel bearings, and check for excessive play or binding in the wheel hubs, which may indicate the distorted wheels or suspension mounting issues flagged in previous MOTs. The front brake pads being worn thin across all quadrants suggests that the braking system has been under significant stress, potentially due to prolonged standing or driving habits that exacerbate pad wear. Inspect the brake discs for scoring, warping, or corrosion, and listen for grinding noises when applying the brakes, which could signal worn pads or damaged discs. Additionally, verify that the brake fluid is clean and at the correct level, as old fluid can lead to brake system failure. For the buyer, the next steps should include replacing the severely damaged rear tyre and addressing the brake pad and disc wear promptly. If the vehicle has been stationary for extended periods, check for standing corrosion on the brake components, particularly the calipers and brake lines, which can cause binding or reduced braking performance. The wheel distortion advisories suggest that the wheels may need realignment or replacement, especially if the vehicle exhibits uneven tyre wear or excessive vibration during cornering. Beyond the immediate defects, conduct a visual inspection of the tyres for sidewall cracking or perishing, which can occur even at low mileage if the vehicle has been stored without proper care. Test the 12V battery and associated electrical systems, as prolonged inactivity can lead to battery discharge or failure. Finally, consider servicing the vehicle’s fluids—oil, coolant, and brake fluid—based on the manufacturer’s recommendations, as fluid degradation accelerates with time, even at low mileage. If the vehicle has a service history, verify that the last service was up to date, particularly for suspension components like coil springs and suspension bushes, which may show signs of wear or fatigue with age.
