2008 SEAT Leon 2.0L Diesel · LS08 OAJ

The most recent MOT test on this 2008 SEAT Leon, conducted on 23 March 2026 at 159,534 miles, resulted in a failure—though no specific defects were recorded. This marks the second consecutive failure in the past year, with the previous test on 27 March 2025 also passing without issues. The pattern suggests intermittent compliance rather than a consistent maintenance routine, as the vehicle has alternated between passing and failing tests without clear resolution of underlying issues. The lack of advisories or defects in any of the five recorded tests implies that, where failures occurred, they were likely minor or procedural, but the repeated failures raise questions about whether critical components—such as brakes, suspension, or emissions systems—have been overlooked between tests. The mileage progression of 159,534 miles today indicates an average of approximately 8,863 miles per year, which is typical for a vehicle of this age. However, the gap between the 2024 and 2025 tests—covering 12,037 miles in just over a year—suggests either consistent usage or prolonged periods without intermediate servicing. There are no extended periods of inactivity, as the mileage increments remain steady without abrupt jumps or prolonged stagnation. This steady accumulation implies wear on high-mileage components such as suspension bushes, coil springs, and brake calipers, which should now be closely examined. Given the absence of recorded defects or advisories in any test, the most critical areas for an in-person inspection would focus on components commonly overlooked in older vehicles. The repeated failures suggest potential issues with brake binding or uneven wear, particularly if the tester flagged rear brakes or caliper function in prior tests. Suspension integrity should be scrutinised for worn or leaking bushes, corroded coil springs, or uneven tyre wear patterns that could indicate misalignment. Additionally, the exhaust system—often a source of minor failures—should be checked for rusted or broken sections, particularly around the catalytic converter and muffler. Structural corrosion, particularly around wheel arches, sills, and the subframe, is another concern given the vehicle’s age, as this can compromise structural integrity without always being detected in standard MOT tests.
