2004 SEAT Leon 1.9L Diesel · LC04 DWM

The most recent MOT test, conducted on 2023-06-05, resulted in a passing grade, though it included several advisories that warrant careful attention. The overall maintenance trend over the past decade is mixed, with a notable pattern of recurring minor issues, particularly with the front track rod end ball joint dust covers, which have been flagged multiple times as deteriorated but preventing dirt ingress—a common problem in high-mileage vehicles where suspension components degrade over time. The 2021 failure highlighted structural concerns, such as the offside rear passenger door’s inability to open from the outside, which suggests potential long-term wear or manufacturing defects in the hinge mechanism. While the 2023 test showed no major failures, the persistence of brake disc wear and tyre perishing advisories indicates that the vehicle’s braking system and tyres are approaching critical thresholds, particularly given the cumulative stress from over 100,000 miles. The recorded mileage of 101,722 miles for a vehicle aged approximately 22 years represents a relatively low annual usage rate of around 4,624 miles per year, which is unusually low for its age. Such low mileage can stem from infrequent use, long periods of inactivity, or environmental factors like storage in damp conditions, but it also raises concerns about potential underuse-related issues. For example, standing vehicles for extended periods can lead to corrosion in brake systems, particularly on the rear discs and calipers, where moisture can cause rusting and binding. Additionally, tyres that have not been rotated or driven regularly may develop uneven wear patterns, and the headlamps’ alignment issues could worsen if not corrected, potentially affecting visibility and safety. The absence of recent high-mileage accumulation suggests that consumables like fluids may not have been replaced at recommended intervals, increasing the risk of premature wear or failure. To proceed with a thorough inspection, the buyer should prioritise checking the suspension components for signs of further deterioration, especially the front track rod ends and Macpherson struts, which have been flagged in prior MOTs. On a test drive, listen for unusual clunking noises from the front suspension, particularly when navigating bumps or corners, as this could indicate worn bushings or binding joints. Inspect the brake system for uneven disc wear, which may suggest caliper binding or warping, and listen for grinding or squeaking noises during braking—these are clear signs of impending failure. The tyres should be examined for sidewall cracking, which is more likely in a low-mileage vehicle that has been stored for prolonged periods, as this can compromise structural integrity. Additionally, verify that the rear passenger door hinge mechanism is fully functional and free from stiffness or binding, as the 2021 failure suggests this may be a persistent issue. For fluid servicing, the buyer should check the brake fluid level and condition, as the advisories on brake pad and disc wear imply that the system may require a flush to remove moisture and contaminants. The coolant and engine oil should also be inspected for signs of degradation, with the oil level and condition being particularly critical given the vehicle’s age. The 12V battery should be tested for voltage output and overall health, as low-mileage vehicles are prone to battery failure if not regularly charged. Finally, a visual inspection of the exhaust system for leaks or corrosion is advisable, though the absence of recent emissions-related failures in the MOT history suggests this may not be an immediate concern. If the vehicle has been stored in a damp environment, a thorough check for rust on the undercarriage and structural components is essential, as this can compromise the vehicle’s long-term roadworthiness.
