2018 Ford Transit Connect 1.5L Diesel · ST68 UEH

The 2018 Ford Transit Connect presents a mechanical picture marked by a cluster of repeated failures within a narrow two-year window, beginning with a dangerous nearside rear tyre lump on 3 November 2023 and followed shortly by a major engine malfunction on 31 October 2024 before clearing on 1 November 2024. This pattern of intermittent breakdowns—first a tyre structural defect and then an engine inoperability—suggests underlying systemic issues rather than isolated incidents, and the fact that the vehicle achieved a clean MOT result in mid-November 2024 indicates that remedial work was completed but raises questions about whether the root causes were fully addressed. The latest test outcome is positive, yet the presence of two separate failures in such a brief span warrants caution for any prospective buyer who wishes to understand the full scope of the vehicle's technical history. Regarding usage, the odometer reading of 65,838 miles over an eight-year ownership period translates to approximately 8,230 miles per year, which aligns reasonably with the expected wear profile for a commercial‑use transit van of this generation. However, the six‑month gap between the 2022 and 2023 passes contrasts sharply with the compressed two‑month interval between the two 2023 failures and the subsequent engine failure in late 2024, indicating that the vehicle experienced deteriorating conditions rather than uniform degradation. While the average annual mileage is modest, the timing of the failures—particularly the engine MIL appearing just months before the tyre issue—points to potential progressive fatigue in critical systems that did not resolve completely between tests. The October 2024 engine MIL (8.2.1.2 h) failure demands particular scrutiny during any test drive. A misfiring engine typically manifests as a rough idle, hesitation when accelerating from a standstill, or a distinctive metallic knocking noise that becomes pronounced under load. Check the engine bay for any fresh coolant leaks or oil contamination around the block, as these can accompany and exacerbate a malfunctioning engine. If the engine runs smoothly now, still verify that the cylinder responsible for the fault has been properly inspected and rebuilt, and confirm that all related sensors and fuel delivery components function correctly before considering the vehicle roadworthy. The 2023 nearside rear tyre lump (5.2.3 d(ii)) remains a relevant safety consideration even after the tyre was replaced, as the structural compromise can persist until the underlying crack propagates further. During a test drive, pay close attention to handling on corners exiting the left side of the vehicle and any vibration transmitted through the chassis when braking lightly. A lumped tyre often produces a pulling sensation or a subtle shimmy that may not be immediately obvious at highway speeds but becomes apparent in city driving. Inspect the tyre visually for residual bulging, cracks, or dry rot, and ensure the wheel alignment was corrected following the repair, because misalignment can accelerate existing damage and create additional handling irregularities.
