2017 Ford Transit 2.0L Diesel · ST17 UPM

A recurring pattern of brake system degradation and fluid leaks defines the mechanical profile of this Ford Transit, with the most recent MOT passed on 22 September 2025 showing an escalating trend in advisories. The record indicates persistent issues with brake pipe corrosion and worn discs, alongside an ongoing oil leak that has been noted in consecutive testing cycles. While the vehicle has avoided outright failures in the recent years, the transition from single advisories in 2022 to multiple, more complex advisories regarding both brake pipe integrity and disc wear in 2025 suggests that wear on the braking system and sealing components is progressing. The vehicle has covered 172,712 miles over its nine-year lifespan, representing an average annual accumulation of approximately 19,190 miles. This high-mileage usage profile is consistent with a commercial vehicle and implies significant cumulative stress on all mechanical consumables, including the drivetrain, suspension, and braking components. Such high annual mileage typically accelerates the wear of rubber bushes, seals, and friction materials, which aligns with the recorded advisories for oil leaks and brake component deterioration. Prospective buyers should focus heavily on the braking system and the source of the reported oil leaks. The advisories specifically mention corroded rear brake pipes covered in grease or other material, which can mask the true extent of structural corrosion on the lines. During a test drive, it is essential to check for any sponginess in the brake pedal, which could indicate air or fluid ingress due to pipe degradation, or any pulling to one side under heavy braking. The reported wear on both front and rear brake discs should be visually inspected for excessive pitting or scoring, and the driver should listen for any grinding noises or feel for pulsations through the pedal, which would indicate uneven disc surfaces. The presence of an oil leak, noted as not excessive in 2024 but present again in 2025, requires careful investigation to identify the specific origin, whether it be a gasket, seal, or oil filter housing. On a test drive, look for any visible smoke or smell of burning oil, particularly after the engine has reached operating temperature, as this can indicate leaks onto hot exhaust components. Given the high mileage and the specific mention of brake pipe corrosion, a thorough underbody inspection is necessary to assess the current state of the chassis and braking lines to determine if the reported corrosion is localized or indicative of wider structural deterioration.
