2004 Ford Focus C-MAX 2.0L Diesel · LS54 EYT

The most recent MOT tests on this 2004 Ford Focus C-Max, conducted just over a year ago on 2025-07-05, reveal a concerning pattern of repeated failures despite identical mileage readings. Both tests at 159,966 miles passed without defects, yet the vehicle failed the prior test just three days earlier at the same mileage—an anomaly that suggests either a temporary administrative error or a critical but intermittent fault not captured in the record. The 2024 cycle similarly shows a failure at 157,359 miles followed by a pass at 157,406 miles, a gap of just 47 miles that implies a rushed or incomplete inspection. While the 2023 test at 153,986 miles passed cleanly, the repeated failures in 2024 and 2025 indicate an unresolved issue that has not been addressed consistently. This suggests either a lack of proper diagnostic follow-up or a fault that fluctuates in severity, such as a failing sensor or intermittent brake binding. The recorded mileage of 159,966 miles over 22 years aligns with typical usage patterns for this vehicle’s age, averaging around 7,271 miles annually. There are no extended gaps suggesting prolonged neglect, nor are there abrupt spikes that would indicate aggressive driving or rapid component wear. The most notable irregularity lies in the 2024 test cycle, where the vehicle failed at 157,359 miles and then passed just five days later at 157,406 miles—a 47-mile increase that does not correlate with typical MOT intervals. This suggests either a misreporting of mileage or a test retake without intervening maintenance, which is unusual for a vehicle of this age. The absence of advisories or defects in the passing tests implies that any recurring issues were either minor or not detected during those inspections. Given the repeated failures without recorded defects, a buyer should prioritise an independent inspection of the braking system, particularly the rear calipers and master cylinder, as binding brakes are a common intermittent fault in this model. The suspension should be thoroughly checked for worn bushes, corroded coil springs, or excessive play in the ball joints, especially given the vehicle’s age. Corrosion around the wheel arches, sills, and subframe should be examined, as structural integrity is critical for safety. The exhaust system should also be inspected for leaks or excessive rust, as emissions-related failures are frequently reported in this model. Finally, the electrical system—including sensors, injectors, and the ECU—should be tested, as intermittent faults often stem from wiring or sensor issues rather than mechanical wear. The lack of advisories in the MOT history does not preclude these problems, so a detailed mechanical and electrical assessment is essential.
