2015 SEAT Leon 2.0L Diesel · CD04 ARM

The most recent MOT test on 2026-06-30 resulted in a failure due to a critical tyre defect on the offside rear tyre—a partial structural failure causing a tear, which is a severe road hazard that must be addressed immediately. While earlier MOTs in 2025 and 2024 showed only advisories regarding tyre wear and child seat restrictions, the 2026 test introduced a dangerous failure alongside persistent advisories on tyre wear and suspension arm bush wear. This pattern suggests a deterioration in tyre integrity and potential underlying issues with the front suspension, which may have worsened over time despite the vehicle maintaining relatively low recorded mileage. The failure rate and severity of defects indicate that the vehicle has not been properly maintained, particularly in high-wear areas like tyres and suspension components, warranting urgent attention before it risks further safety compromises or more costly repairs. The vehicle’s recorded mileage of 52,015 miles at a 2015 model year represents a notably low annual usage rate of approximately 4,729 miles per year, which is unusually low for a car of this age. Such low mileage often correlates with periods of prolonged inactivity, particularly if the vehicle has been stored for extended periods without regular movement. However, low mileage alone does not negate the need for thorough inspection, as standing vehicles can accelerate wear on critical components like brakes, suspension, and fluids through oxidation, corrosion, and degradation. The presence of repeated tyre advisories—particularly the critical rear tyre failure—suggests either neglect during storage or underlying issues that have not been addressed, such as improper load distribution or excessive cornering forces. Additionally, the suspension arm bush wear advisories imply that the vehicle may have been subjected to rough handling or improper alignment, further exacerbating wear patterns. Given the recent MOT failure and recurring advisories, the prospective buyer must prioritise a comprehensive inspection of the tyres, suspension, and braking system. The offside rear tyre failure is a critical issue requiring immediate replacement, as a torn tyre can lead to sudden loss of control or catastrophic failure. During a test drive, listen for uneven tyre wear, which may indicate misalignment or suspension issues, and check for excessive clunking or rattling from the suspension arms, particularly when cornering or over bumps. The front suspension advisories suggest worn suspension bushes, which may cause clunking noises when the vehicle is driven over rough roads or when the steering is turned. Inspect the front wheels for binding calipers or corrosion on brake discs, as standing can cause rust buildup, leading to uneven braking performance or binding during acceleration. Additionally, verify that the brake system is functioning smoothly, with no signs of pulsation or shuddering, which could indicate warped discs or worn brake pads. Beyond the immediate defects, the buyer should also conduct a thorough physical inspection of the vehicle’s structural integrity, fluid levels, and age-related wear. Given the vehicle’s age and low recorded mileage, check the tyres for signs of sidewall cracking or perishing, which can compromise their structural integrity over time. Inspect the 12V battery for corrosion on terminals, as prolonged inactivity can lead to battery failure or reduced starting power. Verify that all fluids—oil, coolant, brake fluid, and transmission fluid—are at the correct levels and free from contamination, as fluids degrade over time even when not used. Check for any signs of fluid leaks around the engine bay, exhaust system, and undercarriage, which may indicate failing seals or gaskets. Finally, ensure that the service history is up to date, particularly for fluid servicing intervals, as the vehicle’s age and usage profile suggest that time-based maintenance should not have been overlooked. If the vehicle has been stored for long periods, consider a thorough inspection of the engine’s internal components for signs of wear or corrosion, as low usage can accelerate oxidation in critical areas.
