Doblo: middle-of-the-pack on first-time pass
Across 58,164 MOT tests, the Doblo returns 71.4% first-time pass — below the UK fleet average. The single most-logged Major fail is windscreen damage. A broken or weak spring and a number-plate lamp out round out the top three. Average tested mileage sits at 83,963, 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.

What owners actually report.
Verbatim faults logged by owners on honestjohn.co.uk over recent years. We didn't summarise — these are the words people typed in.
What's good
The 1.4 16v petrol engine is the perfect range starter with a punchy 95bhp, and like its diesel siblings it complies with Euro 5 emissions standards. Whatever the engine, all models come with Start&Stop and also feature a gearshift indicator to tell you when it's the most fuel-efficient moment to change gear.
Where it falls short
Eight versions of the Doblo featuring seating for up to seven will be available when it goes on sale this month, with prices ranging from £12,295 to £17,145 (OTR). As well as a sophisticated new appearance, all incorporate innovative bi-link rear suspension for a high level of comfort. The longest wheelbase in the segment doesn't just mean more room for passengers but more space for their luggage too, with a roomy 790-litre boot that can be expanded to a class-topping 3200 litres.
Buying or keeping a Doblo?
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 Doblo 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.
