2004 SEAT Leon 1.9L Diesel · OU04 HVY

The recorded MOT history for this 2004 SEAT Leon shows a broadly clean roadworthiness profile across the five tests documented between 2022 and 2025, with the most recent assessment on 15 April 2025 resulting in a pass and no advisories or defects noted. The earlier 2024 and 2023 passes were similarly clean entries, and the lone failure recorded on 11 May 2023 did not carry any defect codes, which means the retest four days later on 15 May 2023 addressed whatever issue was identified without leaving any advisory information on the public record. The overall trend is therefore one of stability at the test pass/fail level, with no chronic advisories pointing to systemic deterioration in specific component groups such as the suspension, braking system, or underbody structure. However, it should be noted that the absence of advisories on older, high-mileage vehicles is unusual and may reflect either prompt rectification of minor issues prior to test or a relatively short advisory history window, rather than the complete absence of wear on a 22-year-old car. At 205,604 recorded miles accumulated over roughly 22 years, the average annual mileage of around 9,346 miles is broadly typical for the platform and age bracket, sitting close to the UK mean for vehicles of this vintage. There are no extended testing gaps in the supplied history that would suggest prolonged periods off the road, which would otherwise have raised concerns about stale brake fluid, perished rubber components, or seized calipers. That said, the cumulative mileage itself is substantial for a Leon of this generation, and components that wear progressively with distance covered, such as engine mounts, gearbox linkages, clutch release bearings, and rear trailing arm bushes, will have been subjected to considerable fatigue cycles regardless of the annual rate. For a prospective buyer, the absence of advisories means there is no specific component flagged for immediate inspection, but the mileage and age warrant a focused mechanical appraisal on the test drive. Particular attention should be paid to the Leon's known weak points, including the front lower wishbone and rear axle bushings, where worn suspension linkages commonly produce clonking or knocking noises over uneven surfaces and vague steering response. Brake pedal feel should be assessed for sponginess or excessive travel, which can indicate corroded brake pipes or seized slider mechanisms on the rear calipers, while a firm pedal with judder under braking would point to warped front discs given the high mileage. The test should also include a check for any signs of oil misting around the cam cover, oil filter housing, and turbo plumbing if the 1.9 TDI engine is fitted, as well as coolant leaks from the header tank and thermostat housing on all variants. During a road test, listen for any driveline vibrations through the pedals or seat at motorway speeds, which on a high-mileage Leon can indicate worn dual-mass flywheel failure or propshaft flex joint deterioration on petrol variants. Steering should remain precise without excess play at the straight-ahead position, and any clonking when turning at low speed should be investigated as a likely worn anti-roll bar drop link or wishbone bush. Inspect the underbody and wheel arches visually for any corrosion bubbling along the rear arch seams, sills, and subframe mounting points, as corrosion advisories would have been expected on a car of this age if present, and their absence should be confirmed by physical inspection rather than assumed. Finally, verify that the clutch bite point is consistent and that there is no clutch slip under load in fourth or fifth gear, as clutch replacement is a common cost on Leons approaching this mileage bracket.
