2015 Ford Transit 2.2L Diesel · BF15 UMU

Brake pipe corrosion is the dominant mechanical theme running through the MOT history of this 2015 Ford Transit, escalating from routine advisories through to major and dangerous failures within the space of twelve months. As early as September 2022, an offside front brake pipe was noted as corroded and coated in grease, and a similar advisory reappeared on pipes running across the rear axle in April 2025. By March 2026 the situation had deteriorated sharply: the nearside and offside rear brake pipes were both classed as excessively corroded, which is a major defect, and within days the vehicle returned for a re-test where the nearside front pipe had also joined the list. A dangerous failure was simultaneously issued for rear brake pads worn below 1.5 mm, which represents a serious safety threshold and suggests the braking system has been allowed to run to the very edge of legal compliance. The most recent test on 1 April 2026 recorded a pass, but only with the front brake pipes still flagged as corroded, meaning the underlying issue has not been resolved, merely deemed passable for the moment. Annual mileage of around 14,902 miles is on the higher side for an eleven year old commercial vehicle of this type, but it is consistent with working rather than garage-queen usage and it aligns with the recurring pattern of wear items appearing across the record. There are clear gaps in the testing history, most notably a four year interval between the 2020 tests and the 2024 entry, which limits visibility of mid-life condition and means wear between roughly 2020 and 2024 is unverified. When testing resumed in March 2024, the front brake pads were already wearing thin, which fits a vehicle that had been covering substantial distance off-record. The 2025 and 2026 entries then show a dense cluster of defects across brake pipes, suspension, tyres, headlamps and steering, suggesting that cumulative use is now exposing multiple ageing systems simultaneously rather than isolated component failures. For a prospective buyer, the rear brake pipework should be treated as the top priority for immediate inspection. The pipe runs across the rear axle have been flagged for corrosion in two consecutive tests, and the rear pipes themselves have already crossed the threshold from advisory into major defect territory. On a test drive, listen for any pulling to one side under braking, feel for a soft or spongy pedal that may indicate pipe swelling or weeping joints, and visually examine the pipes along the axle and underbody for live rust rather than surface discoloration. The rear brake pads also need to be confirmed as recently replaced and bedded in, since the March 2026 record showed them worn below the dangerous minimum; if the work was carried out only just before the re-test, an immediate budget should be set aside for further brake attention given the pipe condition. The front lower suspension arm inner rear bush was noted as at the limit of acceptable wear in 2025, so on test listen for clonking over speed humps and uneven bumps, particularly from the nearside front corner, and check for uneven tyre wear which often accompanies failing Transit bushes. Additional items worth checking include the power steering pipe, which was recorded as leaking at the rack in March 2025, and the headlamps, which failed for incorrect beam image on both sides in the same test. A cold start should be performed so that any drip from the rack onto the subframe or driveway can be identified, and the headlamp pattern should be checked against a wall at night to confirm both sides are now correctly aligned. The windscreen damage recorded in 2025 should also be re-inspected to ensure it has not grown or migrated into the driver's swept view, and the offside non obligatory mirror damaged advisory from 2024 should be confirmed as either repaired or replaced. Given the combination of heavy working mileage, an extended undocumented interval, and the rapid recent escalation of brake and corrosion defects, a pre-purchase inspection with the vehicle raised on a ramp would be strongly prudent, with particular attention to the rear axle pipes, subframe mounting points, and the underside of the offside front suspension arm.
