2013 SEAT Leon 1.2L Petrol · KW13 AAE

The most recent MOT test on the 2013 SEAT Leon occurred on 2025-10-21, where the vehicle passed with a single advisory—an oil leak from the nearside rear inner oil passage, described as not excessive. This follows a pattern of fluctuating results, with the car failing in 2023 and 2025 due to critical mechanical and safety issues, including exposed tyre cords, tyre tread failures, and a severely distorted rear road wheel. While the 2024 and 2022 MOTs were clean, the recurring advisories and past failures suggest a history of persistent mechanical wear, particularly in suspension, tyres, and drivetrain components. The advisory on the oil leak indicates a developing issue that, if ignored, could escalate into a more costly repair, such as internal engine damage or bearing failure. The presence of a previously failed CV joint boot and corroded coil springs further highlights the need for proactive maintenance to prevent further structural and functional degradation. The vehicle’s recorded mileage of 128,857 miles over roughly nine years represents an average annual usage of around 9,912 miles, which is within the expected range for a 13-year-old car in the UK. However, the MOT history suggests periods of either light use or prolonged standing, as evidenced by the frequent failures and advisories, particularly in 2023 when major issues like a non-functional CV joint boot and corroded suspension components were noted. Rapid mileage accumulation could accelerate wear on consumables like brake pads, tyres, and suspension bushes, while prolonged inactivity may exacerbate standing corrosion in the coil springs, exhaust system, and undercarriage. The offside front tyre failure in 2025, with exposed cords and insufficient tread, underscores the importance of monitoring tyre condition regardless of mileage, as tyres can degrade from age, exposure to UV light, or improper storage. For a prospective buyer, the most critical areas to inspect during a physical examination are the tyres, suspension, and drivetrain. Begin with the tyres, checking for signs of uneven wear, cord exposure, or sidewall cracking, which could indicate overuse or poor alignment. The nearside rear oil leak and previous CV joint failure suggest that the CV joint should be visually inspected for boot integrity and any signs of fluid leakage or excessive play during a test drive, where you should listen for unusual whining or clunking noises when turning corners. The corroded coil springs noted in past MOTs may require inspection for stiffness, binding, or structural compromise, particularly if the car has been stationary for extended periods. Additionally, the distorted rear road wheel failure highlights the need to check for warping, uneven rim wear, or excessive run-out when the wheel is removed and balanced. Beyond mechanical checks, the buyer should also verify the vehicle’s service history, particularly for fluid servicing intervals, which for a 13-year-old car should include a full brake fluid flush, coolant change, and oil filter replacement every 60,000 to 100,000 miles or every two years, whichever comes first. The battery should be tested for voltage and capacity, as older vehicles are more susceptible to failure from prolonged disuse or internal corrosion. Finally, the exhaust system and emissions should be inspected for leaks, rust, or structural damage, as the 2023 MOT’s lack of mention of emissions-related issues does not guarantee current compliance, especially if the car has been driven recently. A thorough inspection of the undercarriage for leaks, rust, or damage to the subframe and exhaust manifolds is also essential, given the history of oil leaks and corrosion. If the vehicle has been stored indoors, check for any signs of condensation-related rust on metal components, as this can accelerate wear.
