2012 SEAT Leon 1.6L Diesel · DL12 AEC

The 2012 SEAT LEON demonstrates a stable roadworthiness trend, with the most recent MOT on 2025-12-11 confirming a pass at 108,940 miles. However, a concurrent failed test on the same date, also with no defects recorded, introduces ambiguity. This suggests either a data inconsistency or a technical issue not classified as a defect, such as emissions non-compliance. The absence of recorded faults in prior tests from 2022 to 2024 indicates consistent maintenance, but the 2025 failure warrants scrutiny to confirm resolution. The vehicle’s mileage of 108,940 miles at 14 years old aligns with an average annual usage of 7,781 miles, reflecting typical wear for its age. MOT tests from 2022 to 2025 show annual intervals with incremental mileage increases, avoiding abrupt spikes that might indicate excessive strain. No gaps in testing or irregularities in mileage progression are evident, suggesting the vehicle has been driven within normal parameters. This pattern implies no extreme underuse or overwork, though older models may still exhibit age-related degradation. A buyer should prioritise inspecting the suspension system, particularly suspension bushes and coil springs, which can degrade over time without immediate fault codes. The braking system, including rear calipers and brake discs, merits scrutiny for binding or uneven wear, common in vehicles with high mileage. Structural rust, especially in the underbody or chassis, should be checked, as corrosion can develop unnoticed in older cars. While the MOT history lacks specific mechanical failures, the 2025 failure and the vehicle’s age necessitate a thorough pre-purchase inspection to confirm continued roadworthiness.
