2018 Ford Transit Custom 2.0L Diesel · YP68 ABF

This Ford Transit Custom presents a roadworthiness profile dominated by recurrent electrical and lighting defects on both headlamp and stop lamp circuits, rather than structural or running gear concerns. Across the recorded tests there are three separate stop lamp failures (2025 PRS, 2026 Major) and four headlamp aim or intensity issues, all flagged within the last fourteen months. The pattern is notable because every recorded annual test has identified at least one lighting-related fault, suggesting either chronic adjustment drift, connector corrosion at the lamp units, or underlying wiring issues affecting both the front and rear lighting looms. The most recent recorded outcome on 4 June 2026 shows a clean pass immediately following a same-day failure that addressed all four major lighting defects, indicating these issues were rectified at the test station rather than being symptomatic of deeper electrical faults. Beyond lighting, the only mechanical advisory of note is a deteriorated offside front outer CV boot from the June 2025 test, which remains recorded against the vehicle. The 2024 test was passed without defect, and the 2023 test history is not available within the supplied records, so the overall trajectory cannot be described as consistently clean given the recurring lighting pattern. At 111,519 miles over an eight-year life, this Transit Custom is accumulating roughly 13,900 to 14,000 miles annually, which is a high usage rate for a vehicle of this class and well above the typical commercial van average. This level of annual mileage places proportionally greater demand on wear items including front brake pads and discs, clutch components, dual-mass flywheel, suspension bushes, coil springs, and the constant velocity joints themselves. The mileage progression between recorded tests appears broadly consistent with steady commercial or high-mileage private use rather than extended off-road periods, although the absence of any recorded test before June 2024 limits visibility of earlier wear patterns. Given the mileage, components such as the timing chain, turbocharger actuator, water pump, and dual-mass flywheel will be approaching or already within typical replacement windows for this engine family, even though none of these items have yet been flagged under test. For a prospective buyer, the priority inspection focus should be the offside front outer CV joint boot flagged in June 2025, as a severely deteriorated boot will allow grease loss and eventual joint contamination. On a test drive, listen for clicking or knocking from the front offside wheel on full lock, particularly during slow-speed manoeuvres, and inspect the boot visually for splits, grease fling, or perished edges. Steering should be checked for any vibration through the wheel at speed, which could indicate joint wear or imbalance from grease contamination on the inner CV or wheel bearing deterioration. The CV joint and any associated work should be confirmed as completed, as the advisory has carried forward without re-test. The recurring lighting faults warrant specific attention during a pre-purchase inspection. Both headlamp aim failures (too high in 2026, too low in 2025) and the intensity reduction flag suggest that the headlamp levelling mechanism, adjuster motors, or mounting points should be examined for wear or damage, and all bulbs and connectors verified for corrosion or poor earth contacts. Stop lamp failures on the offside across consecutive years point either to a recurring bulb failure, socket corrosion, or a wiring fault that should be traced rather than repeatedly bulb-replaced. On inspection, check that all lamps illuminate consistently, including main beam, dip beam, side lights, and number plate illumination, and confirm there are no dashboard bulb failure warnings. Finally, given the high mileage, a compression test, coolant system pressure check, and inspection for oil leaks around the engine, power steering rack, and front subframe mounting points would be prudent to anticipate maintenance that has not yet appeared in the MOT record but is likely due.
