2012 SEAT Leon 1.8L Diesel · DL12 ADX

The 2012 SEAT LEON demonstrates stable roadworthiness based on its most recent MOT, conducted on 2025-04-29 at 89,320 miles, which resulted in a pass with no defects recorded. However, the immediate preceding test on 2025-04-28 at identical mileage failed without recorded defects, raising questions about procedural accuracy or transient issues. Subsequent tests from 2023-2024 show consistent passes with no defects, suggesting the vehicle has maintained compliance with safety standards over the past three years. The lack of recurring mechanical failures in these records indicates the car has not exhibited significant deterioration, though the recent failed test warrants scrutiny. The vehicle’s mileage of 89,320 miles aligns with its 14-year age, averaging 6,380 miles annually—a typical rate for this era of vehicle. The MOT history reveals no gaps longer than 12 months, with the longest interval between 2023-04-06 (75,535 miles) and 2024-04-29 (81,567 miles), a 12-month period covering 6,032 miles. This suggests regular maintenance, though the 2023-04-04 failure at 75,535 miles—mirrored by a pass the following day—may indicate a minor, unresolved issue or administrative error. The absence of corrosion, structural defects, or emission-related failures in the records supports the conclusion of generally sound mechanical condition. A buyer should prioritize an in-person inspection of the braking system, given the historical ambiguity around the 2025-04-28 failure, and check for suspension wear, particularly coil springs and bushes, which can degrade over time. The exhaust system and corrosion in body seams should also be examined, as these are common vulnerabilities in 14-year-old vehicles. While the MOT data shows no critical issues, the lack of detailed defect reports limits definitive assurance, underscoring the need for a professional mechanical survey to confirm the vehicle’s integrity.
