2012 Ford Fiesta 1.6L Diesel · YD12 ADZ

The 2012 Ford Fiesta’s most recent MOT on 2025-07-25 at 254,953 miles recorded a pass with no defects, but this followed a failure on 2025-06-27 at 254,894 miles, also with no defects. The prior pass in 2024-07-01 at 150,008 miles and 2023-10-23 at 146,671 miles showed similar outcomes. While the vehicle has maintained roadworthiness in recent tests, the failure just a month before the latest pass suggests potential inconsistency in compliance, possibly due to minor issues or procedural lapses. No structural or mechanical defects were flagged, but the pattern of passing after failing without recorded faults raises questions about the reliability of the testing outcomes. The vehicle’s mileage of 254,953 miles at 14 years old equates to an average of 18,211 miles annually, significantly higher than typical usage. A sharp increase from 146,542 miles in 2023-10-16 to 150,008 miles in 2024-07-01—just 3,466 miles over nine months—suggests intermittent use or periods of inactivity, while the subsequent jump to 254,953 miles by 2025-07-25 indicates intense usage in the final 14 months. This rapid accumulation likely accelerated wear on consumables and mechanical systems, even if no defects were recorded. The sparse defect data limits insight into underlying issues, but the mileage trajectory implies a vehicle subjected to heavy, uneven use. A buyer should prioritise inspecting the suspension, brakes, and exhaust systems, as high mileage increases risks of worn bushes, corroded components, and brake wear. The absence of recorded defects does not eliminate these concerns, particularly given the vehicle’s age and usage. Checking for corrosion, especially in underbody panels and chassis, is critical, as well as assessing brake discs and calipers for uneven wear. The rapid mileage growth also warrants scrutiny of the drivetrain and engine for signs of excessive stress, despite the MOT records showing no immediate failures.
