2017 Ford Transit 2.4L Diesel · DL09 LLG

A pattern of structural and chassis corrosion combined with recurring suspension wear defines the mechanical trajectory of this 2009 Ford Transit, as evidenced by the recent test outcomes. The 2026-01-12 pass was clean, but it followed directly on from a 2025-12-22 failure centred on excessive corrosion at the nearside rear outer suspension mounting point on the sill, which significantly reduced structural strength. An accompanying advisory noted similar but non-excessive corrosion on the offside rear sill, indicating that the structural deterioration is bilateral and progressive rather than isolated. The most recent record therefore masks a serious underlying issue; the vehicle passed only after the nearside sill was presumably repaired, but the offside remains an active corrosion site that will likely deteriorate toward failure if untreated. The recorded mileage history cannot be verified from the available data, and there is insufficient information to calculate an annual accumulation rate or identify any gaps in usage. The vehicle is seventeen years old, yet only seven test events are on file across that span, with the earliest dated 2021-11-19. This irregular testing frequency, with some consecutive-year entries and longer gaps between earlier periods, prevents any meaningful judgement on whether the vehicle has been used consistently, laid up for extended periods, or accumulated mileage at a typical commercial rate. Without corroborated odometer readings, prospective buyers should verify current mileage independently and confirm whether any prolonged off-road periods exist, as corrosion patterns often intensify during storage. From a buyer inspection perspective, the sill and structural mounting corrosion demands close physical examination. The offside rear sill, currently advisory, should be tapped with a knuckle to detect thin or bubbling steel, and a torch should be used to inspect the inner sill box sections and any repair patches from the recent nearside rectification, checking for weld quality and underseal coverage. With the vehicle loaded or unladen, listen for clonks or rear-end shifting over bumps, which would indicate that the suspension mounting points have lost further integrity. The nearside rear brake pipe, flagged as corroded and grease-covered across three consecutive tests from 2023 onwards, should be inspected along its full length for rust bloom, and the pedal should be tested for sponginess or excessive travel under firm application. Given that the 2021 failure related to an airbag system warning lamp, confirm that the supplementary restraint system warning lamp extinguishes promptly on ignition and that no recalls or previously disconnected airbag components remain unresolved. Suspension components warrant particular attention during any test drive. Anti-roll bar ball joint dust covers have failed twice, on both nearside and offside front positions in 2023 and 2025 respectively, indicating that the joints themselves may now be approaching wear-out; listen for metallic knocking or rattling over uneven surfaces and during direction changes, which would confirm excess play. The front lower suspension arm rear bushes, flagged on both sides in 2023, should be checked for movement by hand under load, and any wandering or instability at speed would suggest the bushes have progressed beyond advisory tolerance. The nearside rear shock absorber, noted for light oil misting in 2022, should be inspected for heavier seepage, and the vehicle should be pushed down at each corner to verify even damping rebound. Finally, given the front brake disc advisories recorded in 2025, test the brakes firmly from speed to detect any pedal judder or vibration through the steering wheel, which would indicate the discs have worn beyond acceptable limits and require replacement.
