Compared with cars of the same age
Older cars fail more often, so a model that’s mostly a few years old will look better than one that’s mostly 12. These figures compare like with like.
At 3–5 years
72.0%
All cars: 86.1% (14.1 points worse). 186 tests.
At 6–10 years
56.3%
All cars: 76.1% (19.8 points worse). 1,198 tests.
At 11 years and over
54.8%
All cars: 61.3% (6.5 points worse). 8,351 tests.

Most common reasons for failing
- Component mounting prescribed areas: prescribed area excessively corroded significantly reducing structural strength failed 18.2% of tests
- Rear fog lamp: not working failed 6.9% of tests · what this means

- Ball joint dust cover no longer prevents the ingress of dirt failed 4.9% of tests · what this means
- Headlamp aim: projected beam image is obviously incorrect failed 4.9% of tests · what this means
- Linkage ball joint dust cover: ball joint dust cover no longer prevents the ingress of dirt failed 4.2% of tests · what this means
- Chassis condition: or chassis has excessive corrosion, seriously affecting its strength within 30cm of a body mounting failed 3.9% of tests · what this means
- Chassis condition: corroded to the extent that the rigidity of the assembly is significantly reduced failed 3.3% of tests · what this means

About these figures
- They cover every Bongo version DVSA records under this name (engines, trims and generations together), on its first MOT test of each visit. A “pass with rectification” (fixed within an hour) counts as a fail, as in DVSA’s own statistics.
- Cars under three years old are left out, because the few tested that young are mostly taxis.
- Fuel mix of the cars tested: petrol 52.5%, diesel 46.5%, liquefied petrolum gas (lpg) 0.9%.
- A pass rate describes the model, not any one car. How a car has been looked after matters more.
