2018 SEAT Leon 1.5L Petrol · DE68 ABO

The latest MOT test on the 2018 SEAT León recorded a passing outcome on 2026-06-19, with the vehicle maintaining a stable maintenance profile over the past three years. While there are recurring advisories related to the offside front shock absorbers showing light oil misting, which indicates potential internal wear or leakage without immediate failure risk, the vehicle has otherwise passed all subsequent tests without major defects. The consistent passing of the rear child seat advisory—due to its installation preventing full inspection of the adult seat belt—suggests the issue is unrelated to the vehicle’s structural or functional integrity but rather a practical limitation of the fitment. This stability is encouraging, though the tyre-related advisories from 2024 and 2025 warrant closer attention, as they point to wear and potential degradation that could compromise safety if left unaddressed. The recorded mileage of 42,294 miles for an eight-year-old vehicle represents a notably low annual usage rate of approximately 5,287 miles per year, which is unusual for its age. Such low mileage often correlates with extended periods of the vehicle being stationary, particularly in climates prone to standing corrosion or fluid degradation. This could explain the recurring oil misting in the offside front shock absorbers, as standing fluids can accelerate internal wear or corrosion in mechanical components. Additionally, the rear tyres showing signs of cracking or perishing—despite the relatively low mileage—may reflect prolonged exposure to environmental factors such as UV degradation, ozone, or temperature fluctuations, which accelerate sidewall deterioration even with minimal rolling. Buyers should consider the implications of this usage pattern, as it may require more frequent or thorough checks of consumables and components prone to standing-related issues. To proceed with a thorough inspection, the prospective buyer should prioritise examining the suspension components for signs of further wear or leakage beyond the current oil misting. On a test drive, listen for unusual clunking noises from the offside front suspension, particularly when the vehicle is driven over bumps or at low speeds, as this could indicate failing shock absorbers or deteriorating suspension bushes. Inspect the rear tyres for any signs of excessive cracking, delamination, or uneven wear patterns, as these can signal underlying issues such as improper alignment, poor tyre pressure, or suspension failure. The buyer should also verify the condition of the front tyres, particularly the near-side, which was noted as worn close to the legal limit in the 2023 MOT. Check for uneven tread wear, bulges, or sidewall damage, as these can compromise traction and handling. For a vehicle of this age and mileage, particularly one with extended periods of inactivity, the buyer should conduct a comprehensive inspection of the following critical areas: the 12V battery and associated electrical system, as prolonged standing can lead to corrosion or discharge; the brake system, including checking for corrosion on brake discs, warping, or binding calipers, which may result from moisture ingress or prolonged idling; and the fluid levels and condition of the engine oil, transmission fluid, and coolant, as these fluids degrade over time even when the vehicle is not in use. Additionally, verify that the service book has been updated for time-based maintenance, such as the replacement of the engine oil and filter every 15,000 miles or six months, whichever comes first, and the inspection of the exhaust emissions system for any signs of blockages or corrosion. Finally, assess the vehicle’s structural integrity by looking for any signs of rust, particularly around the underbody, wheel arches, and rear suspension components, as these areas are most susceptible to corrosion from prolonged exposure. If the buyer is concerned about the child seat advisory, they may wish to consider removing it temporarily to allow a full inspection of the adult seat belt system during the test drive.
