2021 Ford Transit 350 Leader Ecoblue 2.0L Diesel · HT70 OXU

This particular Transit 350 Leader EcoBlue has accumulated two MOT failures in quick succession, both for relatively minor but telling reasons, which suggests an element of deferred maintenance rather than fundamental structural decay. The 2026 test produced a fail because the nearside front mirror repeater was damaged to a point where it was judged likely to cause injury, a major classification that took the vehicle below pass standards, while a 2025 fail was triggered by an offside wiper not clearing the windscreen effectively, again a present-and-correctable item. Both retests on the same day passed cleanly, which is the standard outcome once the defect is remedied, but the pattern is worth noting. Underlying advisories from those same tests point to a half-shaft oil seal seeping on the nearside rear and perishing on the offside front tyre, plus a minor mirror issue, meaning the current keeper is patching the vehicle rather than addressing developing wear. With five years on the road and 80,032 miles on the odometer, this Transit has covered roughly 16,000 miles annually, which is a notably high accumulation rate for a commercial vehicle of this age and is consistent with sustained operational use rather than seasonal or light-duty deployment. There are no gaps in the MOT record and no concerns about long periods of standing, so the mechanical wear pattern can be read as a direct function of working life: brake friction material, suspension bushes, drivetrain oils, and underbody protection will all have endured continuous loading. The 2024 pass recorded no defects at all, but the 2025 advisory on rear inner brake pads wearing thin, combined with the half-shaft seal seepage flagged the following year, demonstrates how wear items have begun to surface as the vehicle climbs beyond the mid-life mileage band where commercial components typically demand closer attention. For a prospective buyer, the priority areas on inspection should centre on the items the MOT examiner has already drawn attention to, starting with the nearside rear half-shaft oil seal. While classed as not excessive, an oil leak at this joint will progressively contaminate the surrounding components and the inner CV joint, so it warrants a physical examination on a ramp for active seepage, oil misting on the driveshaft gaiter, and any signs of grease loss from the CV itself. On the road, listen for clicking or clonking from the nearside rear under load or full steering lock, and watch for vibration through the floor at higher speeds. The offside front tyre flagged for perishing should be inspected for sidewall cracking, tread depth across the full circumference, and any uneven wear patterns that might indicate an alignment or suspension geometry issue, particularly given the high annual mileage. The brake system deserves particular scrutiny because the rear inner pads were recorded as wearing thin just over a year ago and the vehicle has since covered a substantial working mileage. Check the pedal feel for excessive travel or sponginess, listen for any binding or grinding from the rear calipers on a slow drive with the windows down, and verify that the handbrake holds firmly on an incline as rear drum or caliper mechanisms on heavily loaded vans commonly seize when underused. The bodywork around the nearside front should be examined for any sharp edges or exposed fixings where the mirror repeater was damaged, and the wiper mechanism on the offside should be observed in operation to confirm full sweep coverage, not just a parked inspection. Finally, given the continuous high mileage, inspect the underside for any developing corrosion on suspension arms, subframe mounting points, and brake lines, and confirm that the van drives without any clonks from the front anti-roll bar bushes or drop links over speed humps, as these are common Transit wear items that would not yet have triggered an advisory but are likely approaching the threshold.
