2018 SEAT Leon 1.6L Diesel · SA18 DWM

The most recent MOT test on 2026-04-02 resulted in a passing outcome, though it did not entirely clear the vehicle of advisories or minor issues. The overall maintenance trend over the past two years shows a pattern of recurring advisories and one major failure related to headlamp alignment and suspension condition. While the latest test passed, the persistence of light misting in the front and rear shock absorbers, thin brake pads, and tyre wear close to legal limits suggests that the suspension and braking systems are under significant stress, likely due to the high mileage and potential for cumulative wear. The presence of undertrays also indicates either a custom modification or prolonged exposure to harsh conditions, which may accelerate corrosion or debris ingress into critical components. The vehicle’s recorded mileage of 110,664 miles at the age of eight years represents an annual usage rate of approximately 13,833 miles, which is notably high for its age. Such high mileage typically correlates with increased wear on consumables like brake pads, tyres, and suspension components, as well as potential stress on the drivetrain and exhaust system. While lower mileage might suggest periods of inactivity or lighter use, the absence of significant mileage gaps in the MOT history implies consistent, likely aggressive driving conditions. This could contribute to accelerated wear in the suspension bushes, shock absorbers, and brake systems, as well as potential tyre degradation from uneven loading or overuse. Given the recurring advisories and high mileage, the buyer should conduct a thorough inspection of the suspension and braking systems. During a test drive, listen for unusual clunking or rattling noises from the front and rear suspension, which may indicate worn or failing suspension bushes, broken coil springs, or damaged strut mounts. Check for uneven tyre wear patterns, particularly on the inner edges of the front tyres and the rear tyres, which could signal misalignment, poor suspension alignment, or camber issues. Inspect the brake system for signs of pulsation or shudder during braking, which may indicate warped discs or binding calipers, and verify that the brake pads are not scoring or grinding against the discs. Additionally, visually inspect the brake discs for corrosion or excessive glazing, especially if the vehicle has been stored for extended periods. For fluid systems, the buyer should prioritise checking the condition of the brake fluid reservoir, engine oil, and coolant, as these fluids degrade over time regardless of mileage. Given the advisories on brake pad wear and suspension oil misting, it is prudent to ensure the brake fluid is fresh and free from moisture contamination, which can compromise braking performance. The engine oil should be checked for signs of sludge or contamination, and the coolant system should be inspected for leaks or corrosion, particularly around the radiator hoses and water pump. Finally, with the vehicle’s age and high mileage, the battery should be tested for voltage output and overall health, as older batteries may struggle to maintain charge cycles efficiently. If the battery is more than five years old, consider replacing it to prevent issues with electrical systems or starter reliability. The tyre tread depth should also be verified, with a focus on the offside rear tyre for any signs of cracking or perishing, which could compromise grip and safety.
