2017 Ford Transit 2.0L Diesel · CV67 FSC

A progressive pattern of brake pipe corrosion sits at the centre of this Transit's mechanical story and is the principal area demanding close attention. The earliest recorded advisory appears in September 2023, when front and offside rear brake lines were noted as corroded but covered in grease or other material. By the September 2024 retest, the nearside front pipe had deteriorated to a Major defect, resulting in a fail, while four other brake lines along the front-to-rear and cross-axle runs were simultaneously flagged as corroded. The most recent test on 29 September 2025 returned a Pass with an advisory for general underbody corrosion, meaning no specific brake line item was recorded that year, but the cumulative picture across 2023 and 2024 is one of widespread surface and structural oxidation across virtually the entire brake pipe circuit. The lighting-related Major defects from the 2024 fail (dipped beam, reversing lamp, side repeater lens) are isolated items and do not indicate a wider electrical concern. Mileage accumulation is notably high for the vehicle's age. At 125,781 miles over approximately nine years, the average is close to 14,000 miles per year, which is well above the typical figure for a vehicle of this type and points to sustained commercial or heavy-duty use. Annual MOT intervals have been consistent since 2020, with no extended gaps in testing, which removes any uncertainty around prolonged standing periods. The implication of this usage profile is that wear-rate items such as suspension bushes, coil springs, wheel bearings, brake discs and pads, clutch components, and drivetrain mounts will have been worked hard throughout the vehicle's life, and any current condition assessment should assume these consumables are closer to replacement thresholds than a lower-mileage equivalent. For a prospective buyer, the brake pipe condition is the single most important physical inspection point. The advisories on the front-to-rear and cross-axle runs mean that corrosion is not confined to one localised area, so a thorough underbody examination on a ramp is essential, with particular attention paid to the pipe runs along the chassis rails, across the rear axle, and around the fuel tank area where road grime and moisture collect. Any visible pitting, flaking, or rust-through must be treated as a likely immediate requirement, and the cost of a full brake pipe replacement on a long-wheelbase Transit is not insignificant. During a road test, the buyer should listen for any scraping or metallic noise from the wheel areas under light braking, feel for a soft or spongy pedal that may indicate a weeping joint rather than merely perished rubber flexi-hoses, and check for any visible brake fluid leaks beneath the vehicle after it has been stationary. Suspension and general underfloor integrity warrant equally close scrutiny given the recorded underbody corrosion advisory and the high annual mileage. On the test drive, listen for clonks or knocks from the front suspension over speed bumps and uneven surfaces, which would indicate worn anti-roll bar drop links, control arm bushes, or top mount bearings — all common Transit failures at this mileage band. Steering should remain precise with no vagueness through the straight-ahead, and any pulling to one side under braking would reinforce concerns about the brake calipers or pipework. Check that all exterior lighting functions correctly, including the dipped beam, reversing lamp, and side repeaters previously flagged, and inspect the tyres for uneven inner or outer shoulder wear, which on a high-mileage Transit is frequently the first visible sign of worn suspension geometry before any noise becomes apparent.
