The picture
Across 635 MOT tests, the Transit Custom 340 Trend Eblue returns 79.7% first-time pass — roughly in line with the UK fleet average. The single most-logged Major fail is windscreen damage. Brake pads worn below 1.5 mm and wipers that don't clear the screen round out the top three. Average tested mileage sits at 57,467, which is the lens to read those failure rankings through. If you own one and the next test is close, the ranked list below is a sensible pre-test checklist.

Year-band analysis
First-time MOT pass rate split by registration band. Pass rates barely move across bands here, so the year you buy Ford Transit Custom 340 Trend Eblue makes little measurable difference to MOT outcomes.
Best band to buy
79.8%
2018–2020 registration
the 2018–2020 band climbs to 79.8% — a 0.9-point improvement. Failures here are mostly wear items: damaged but not adversely affecting driver's view, does not clear the windscreen effectively — the structural issues that drag down older examples don't appear in the top-10 for this band.
Band to be cautious about
78.9%
2021+ registration
On the 2021-on band, the data shows a 78.9% pass rate against a fleet average of 79.8% on the newer band. The main culprits logged at test: damaged but not adversely affecting driver's view, does not clear the windscreen effectively, and less than 1.5 mm thick. Average mileage on test for this band is 51,566 miles — high-mileage wear items are a recurring theme.
Best band to buy: 2018-2020 (79.8% first-time pass). Worst band to avoid: 2021+ (78.9% pass). That's a 0.9-point spread across 802 older tests and 943 newer ones — year of build makes a material difference on this model.
