The picture
Across 1,814 MOT tests, the Vivaro 3100 Edition S/S returns 74.9% first-time pass — below the UK fleet average. The single most-logged Major fail is wipers that don't clear the screen. A number-plate lamp out and brake pads worn below 1.5 mm round out the top three. Average tested mileage sits at 42,838, 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. A 3.2-point gap between bands means the year you buy Vauxhall Vivaro 3100 Edition S/s has a real effect on what turns up at the garage.
Best band to buy
76.2%
2021+ registration
the 2021-on band climbs to 76.2% — a 3.2-point improvement.

Band to be cautious about
73.0%
2018–2020 registration

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 Edition 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.
