The picture
Across 1,754 MOT tests, the Vivaro 3100 Dynamic S/S returns 75.4% first-time pass — roughly in line with the UK fleet average. The single most-logged Major fail is wipers that don't clear the screen. Brake pads worn below 1.5 mm and a defective wiper blade round out the top three. Average tested mileage sits at 45,773, 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.

Best band to buy
76.4%
2018–2020 registration
the 2018–2020 band climbs to 76.4% — a 4.8-point improvement. Failures here are mostly wear items: does not clear the windscreen effectively, damaged but not adversely affecting driver's view — the structural issues that drag down older examples don't appear in the top-10 for this band.
Band to be cautious about
71.5%
2021+ registration
On the 2021-on band, the data shows a 71.5% pass rate against a fleet average of 76.4% on the newer band.

Use the failure ranking as a pre-test checklist or a haggling lever. Treat the headline pass rate as a fleet-wide trend, not a guarantee on any individual car.
If you own a Vivaro 3100 Dynamic S/s and your last MOT looked nothing like the ranked failures above, that's normal — individual cars vary widely. The ranking shows the patterns testers flag most often across the country.
