Vauxhall Vivaro 3100 Sportive S/s MOT Failures
An analysis of 13,831 real DVSA MOT tests on the Vauxhall Vivaro 3100 Sportive S/s — what fails, how often, and how that compares to every other car on UK roads.
Where the Vauxhall Vivaro 3100 Sportive S/s fails its MOT
The single biggest MOT failure point on the Vauxhall Vivaro 3100 Sportive S/s is light unit fault — this model is 8.7 times more likely to fail on this item than the average car on UK roads. That makes it worth watching for anyone buying or owning this model. Across 13,831 MOT tests, 0.5% of all Vauxhall Vivaro 3100 Sportive S/s tests recorded this as a failure.
Lighting faults are usually straightforward to fix (bulbs, connectors, earth points) but can indicate deeper wiring issues on older cars. Check all lights including fog lamps, number plate lights, and dashboard warning lights.
Other notable weak points include emissions failure (6.8x the fleet average), rear registration plate lamp or light source mi... (6.5x the fleet average), fluid leak (5.7x the fleet average), and brake fluid significantly below minimum mark (5.7x the fleet average). These ratios compare the Vauxhall Vivaro 3100 Sportive S/s's failure rate on each item against the national average for all cars tested — a ratio of 10x means this model fails ten times more often than a typical car.
The failures span 5 categories: Lights & Electrics, Exhaust & Emissions, Brakes, Wipers & Windscreen, Bodywork. If you're inspecting a Vauxhall Vivaro 3100 Sportive S/s before purchase, these are the areas to focus on — and if any have been flagged as advisories on a previous MOT, they're likely to become failures in the near future.
How failures change with mileage
The Vauxhall Vivaro 3100 Sportive S/s's weak points shift as the car covers more miles. Understanding these patterns helps you know what to expect — and what to budget for — at each stage of ownership.
Under 60,000 miles
At this mileage, most failures are either design-related or caused by age rather than wear. Components like bushes and drop links may not have been replaced yet, and original-fit parts can deteriorate even on low-mileage cars that spend a lot of time sitting.
For the Vauxhall Vivaro 3100 Sportive S/s specifically, the DVSA data shows the most common failures at this mileage are light unit fault (8.7x the average) and rear registration plate lamp or light source mi... (6.5x). fluid leak (5.7x) and brake fluid significantly below minimum mark (5.7x) also appear frequently.
60,000 to 100,000 miles
This is where routine wear items start to show up. Brake components, tyres, and exhaust parts have done serious work by this point. Cars that have been well serviced will show fewer of these failures — this mileage band is where good maintenance really separates the well-kept from the neglected.
The standout failure at this mileage is wiper fault at 5.7x the fleet average.
Over 100,000 miles
High-mileage cars accumulate failures across multiple systems. The key question isn't whether things will need doing — they will — but whether the car has been maintained well enough to keep on top of them. Look for a consistent service history and recent MOT passes with minimal advisories.
The standout failure at this mileage is emissions failure at 6.8x the fleet average.
The shift from light unit fault at lower mileages to emissions failure at higher mileages is typical — early failures tend to be design or factory-related, while high-mileage failures reflect accumulated mechanical wear. A car that's been well maintained will usually dodge the worst of both.
