2015 Ford Transit 2.2L Diesel · ST15 OSW

The most recent MOT test on the 2015 Ford Transit recorded a failure in September 2025, highlighting critical issues with the anti-lock braking system (ABS) and severely corroded brake pipes across all four positions. This failure contrasts sharply with the vehicle’s previous MOT history, which shows a pattern of passing tests with only minor advisories—such as worn suspension bushes, corroded sub-frame, and thin brake pads—indicating that the ABS and brake pipe corrosion are new or significantly advanced defects. While the earlier advisories suggest gradual wear progression, the sudden appearance of major failures in 2025 points to either a lack of recent maintenance addressing these components or underlying structural or manufacturing issues that have now reached critical thresholds. The advisory from 2023 about grease or material buildup on brake pipes further implies that corrosion may have been present but not previously flagged due to the absence of visible leakage or excessive corrosion at the time. The vehicle’s recorded mileage of 92,147 miles over approximately 11 years represents an average annual usage of around 8,377 miles, which is within the expected range for a Transit of this age and class, particularly if it has been used for commercial or mixed driving purposes. However, the significant gap between the 2023 and 2025 MOT tests—two years without testing—suggests the vehicle may have been stationary for extended periods, which accelerates issues like corrosion, fluid degradation, and standing corrosion on components such as brake pipes and suspension mounts. The absence of higher mileage accumulation in recent years does not necessarily mitigate the risk of hidden wear, especially in the drivetrain and braking systems, where prolonged inactivity can lead to binding calipers, seized brake components, or fluid separation in hydraulic systems. The gearbox mounting advisories from 2019 to 2021, while not failing, indicate a recurring concern that should be addressed before high-mileage driving resumes. Given the critical ABS and brake pipe failures from the 2025 MOT, the prospective buyer must prioritise immediate rectification of the anti-lock braking system and the corroded brake pipes. The ABS fault could stem from a failing sensor, wiring issue, or hydraulic failure within the system, and any attempt to drive the vehicle without resolving this will void the warranty and compromise braking performance. The corroded brake pipes are a major safety hazard, as they risk rupturing under pressure, leading to catastrophic brake failure. Inspection should include checking for brake fluid leaks around the pipes, testing brake pedal travel and response under acceleration, and verifying that the ABS warning light is fully cleared after repairs. Listen for unusual noises from the brakes, such as grinding or squeaking, and inspect the brake discs and pads for uneven wear or binding, which may indicate caliper issues exacerbated by the corrosion. Additionally, the perished suspension bushes and corroded sub-frame from previous advisories should be monitored closely, as these can lead to excessive body movement, alignment issues, or structural fatigue over time. For the buyer’s broader inspection, focus on the brake system’s full functionality, including a test drive to assess pedal firmness, brake fade under sustained use, and the absence of vibration or shuddering. The gearbox mounting advisories suggest that the vehicle may have experienced minor vibrations or uneven power delivery, so check for excessive play in the transmission area or unusual noises during gear changes. Inspect the suspension for uneven tyre wear, which could indicate misaligned wheels or worn control arms, and listen for clunking noises when driving over bumps, as these may signal worn suspension bushes or damaged coil springs. Given the vehicle’s age and the history of corrosion, particularly in the brake pipes and sub-frame, thorough visual checks for rust, particularly around wheel arches, exhaust systems, and undercarriage, are essential. Finally, verify that the service history includes regular fluid top-ups, especially brake fluid, which can degrade over time even without use, and ensure the 12V battery is in good condition, as prolonged inactivity can lead to corrosion in terminals or a failing alternator. If the vehicle has been stored for extended periods, consider a full fluid flush and a check for any moisture ingress that could accelerate corrosion in the electrical and hydraulic systems.
