How we count this. Data: UK MOT open data, 2025. Only Class 4 cars on their first MOT of the year are counted. A car that fails and is fixed at the test station still counts as a fail in the first-attempt rate. These are raw results, not adjusted for age, mileage, or peer mix. The MOT does not test engine or gearbox internals.
These are patterns across 2006 Mercedes-Benz Vito vehicles in 2025, not a prediction that any one car will have them. Faults are grouped by part of the car. They come from MOT defect codes, not manufacturer bulletins, recalls or a diagnosis of any one car.
Body and structure
Three faults. The strongest is the drive shaft joints and boots (rear): 20 times as often as on similar cars.
Figures below are measured across the 1,204 of 1,242 failed first attempts (96.9%) that recorded an odometer reading in 2025. Mileage is needed to compare like with like. 3.1% of failures are excluded because no mileage was recorded, so treat these shares as indicative for this model year.
We only list faults with at least 20 failures and a rate of about 2.0 times that of similar cars, which keeps one-off results out of the list.
Drive shaft joints and boots (rear)
Vehicle structure condition (front)
What it means
Structure that is fractured, deformed, corroded, modified or inadequately repaired is failed on rigidity only if the overall structural rigidity of the vehicle is significantly reduced. Structure that is likely to affect steering or braking adversely is graded Dangerous. Prescribed areas are not covered here, as they are checked under other sections, including brakes and steering.
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 39 first tests, 4.9 times as often as on similar cars.
Chassis condition (front)
What it means
A main load-bearing structural member that is fractured, deformed, modified or inadequately repaired is Major when structural rigidity is significantly reduced, and Dangerous where steering or braking is likely to be adversely affected. Corrosion of the body, cab or chassis at a mounting point is Dangerous where overall security or stability is impaired.
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 29 first tests, 3.5 times as often as on similar cars.
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage. Advisories count notes recorded on failed first tests only.
Suspension
Three faults. The strongest is the suspension sub-frame mounting area (front): 11 times as often as on similar cars.
Suspension sub-frame mounting area (front)
What it means
Structure around a sub-frame mounting that is so weakened that control of the vehicle is likely to be adversely affected is graded Dangerous, whether it is damaged, fractured, corroded or inadequately repaired. It is Major when strength is significantly reduced by excessive corrosion, damage or a fracture, or when it is inadequately repaired.
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 35 first tests, 7.0 times as often as on similar cars.
Suspension mounting area (front)
What it means
The load bearing structure within a set distance of a sub-frame, spring or suspension component mounting is a prescribed area. Major applies when its strength or continuity is significantly reduced or it is inadequately repaired. Dangerous applies when it is so weakened that control of the vehicle is likely to be adversely affected.
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 33 first tests, 3.3 times as often as on similar cars.
Anti-roll bar pins and bushes (front)
What it means
An anti-roll bar pin or bush that is excessively worn is Major, and one likely to become detached is graded Dangerous. The wording is DVSA's general rule for a suspension pin, bush or joint.
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 31 first tests, 2.7 times as often as on similar cars.
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage. Advisories count notes recorded on failed first tests only.
Brakes
Three faults. The strongest is the handbrake lever: 3.7 times as often as on similar cars.
Handbrake lever
Rigid brake pipes (front)
What it means
Chafing, corrosion or damage to a rigid brake pipe justifies rejection once its wall thickness is reduced by a set amount, although DVSA accepts this is not easy to determine. If a tester is not sure, the benefit of the doubt applies. A leaking pipe or connection is graded Dangerous on a hydraulic system and Major on an air system.
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 188 first tests, 3.0 times as often as on similar cars.
Electronic stability control
What it means
An ESC warning lamp is failed only when the tester is certain it indicates an ESC malfunction, because the lamp takes various forms and the owner's handbook may need checking. The system is also called ESP, VDC or DSC, among many other names. Every failure row is Major, covering the lamp, wheel speed sensors, wiring, other components and the switch.
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage. Advisories count notes recorded on failed first tests only.
Steering
One fault: steering rack (front), 2.9 times as often as on similar cars.
Steering rack (front)
What it means
Steering gear casing retaining devices dangerously loose, or visible relative movement to the chassis or bodywork, is graded Dangerous. A casing not properly attached, or fractured, is Major, but a fracture that affects the stability or attachment of the casing is Dangerous. A gaiter damaged but still keeping dirt out is Minor, and Major once missing or no longer doing so.
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.
Advisories
Other things testers noted as worn or close to failing, more often than on similar cars.
An advisory is a note from the tester about something that has not failed yet. It is an early warning, not a fail. Advisories for the faults above are shown with those faults.
Transmission oil leaks (rear)
Individual direction indicators (front)
Data: UK MOT open data, 2025. Counts cover advisories recorded on failed first tests only, compared with cars of the same age and mileage.
MOT pass rates
How first tests ended, and how the pass rates are counted.
- Passed first time
- 56in every 100
- Passed on the first test.
- Fixed at the station
- 9in every 100
- Failed, then fixed at the test station the same day.
- Failed
- 35in every 100
- Did not pass, and were not fixed at the test station.
First-attempt pass 56.4% of 2,846 first tests (2025): only cars that passed first time count. Official-style pass 64.6%: cars fixed at the test station also count as a pass. The 9 fixed and the 35 not fixed make the 44 in every 100 that did not pass first time.
Same model, other years
Passed first time in every 100, all tested in 2025.
Newer cars are younger, so look for a jump rather than the climb. A year earlier (2024), when these cars were a year younger, 55 in every 100 passed first time.

If you are buying one
What this year's MOT record means for the decision in front of you.
Mileage makes little difference on a 2006 Vito.
Of 2006 Vito vehicles with under 122,000 miles, 58 in every 100 passed their 2025 MOT first time. With 218,000 miles or more, 59 in every 100 did.
What to check at your mileage
How often each fault turned up on a failed first test, by the car's mileage. Read it as: what is likely to need looking at on a car like the one in front of you.
| Under 122,000 | 152,000–180,000 | 218,000 and over | |
|---|---|---|---|
| Handbrake efficiency below minimum (roller test) | 5.2 | 10.0 | 7.5 |
| Suspension mounting area (rear) | 3.1 | 6.3 | 7.1 |
| Individual sidelight or tail light (front) | 2.5 | 6.9 | 5.8 |
| Windscreen washers | 4.5 | 2.2 | 4.0 |
| Headlight aim | 4.2 | 3.8 | 3.3 |

Every figure here is a first-attempt MOT rate from DVSA open data for this model line, for cars of this model year tested in 2025. Each mileage band holds a fifth of the tests. MOTs do not test engine or gearbox internals, so this is a pre-purchase checklist, not a full reliability score.

Short answers about how to read this model-year guide.
About this data
How this page is built and what it can (and can't) say.
These figures come from UK MOT open data for this model year. We surface common failure patterns against similar cars, not a full reliability score, and not a pass/fail verdict on any individual vehicle.
What we include
UK Class 4 cars only. Normal MOT tests (not retests); first test per vehicle per calendar year; results pass, PRS, or fail.
Same-day repairs
PRS means the car failed items that were fixed at the test station and then passed the same day. We count PRS as a first-attempt fail in headline rates so same-day repairs do not hide problems.
How we compare
We compare this model year with other Class 4 cars of similar age and mileage in the same test year. This model family is left out of the peer group so the car is not measured against itself.
What this does not cover
- MOTs do not cover engine internals, gearboxes, or many electronics; this is not a full reliability score.
- Common faults come from MOT defect stats, not manufacturer TSBs or recalls.
- Age and mileage matching reduces, but does not remove, differences in how cars were used and maintained.
- If the data for a car is too thin to say anything useful, we say so rather than guess.
