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 2008 Peugeot Partner 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.
Lamps and electrical
Three faults. The strongest is the horn: 9.2 times as often as on similar cars.
Figures below are measured across the 1,157 of 1,158 failed first attempts (99.9%) that recorded an odometer reading in 2025. Mileage is needed to compare like with like.
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.
Horn
What it means
A horn that does not work, or is likely to be confused with an emergency vehicle siren, is graded Major. Gongs, bells, sirens and anything with more than one tone, which includes a horn that alternates between its notes, are not allowed, except a gong, bell or siren on vehicles first used before a set date. Sound defects are Minor for named cases such as a bell or harsh sound, and Major under a general row.
Individual direction indicators (front)
What it means
Direction indicators must be amber, though vehicles first used before a set date may have white at the front and red at the rear when the indicators are combined with stop or position lamps, and sequential or dynamic ones are not a reason to fail. A lamp that is missing, inoperative or has more than half of a multiple light source not functioning is graded Major. A flashing rate outside the permitted range is graded Minor.
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 26 first tests, 2.7 times as often as on similar cars.
Brake light
What it means
All stop lamps missing or not working is graded Dangerous, and so is a stop lamp that stays on when the brakes are released. A stop lamp that is missing or not working is Major. On some vehicles with LED rear lamps, part of the stop lamp can go out when the rear fog lamp is lit, which is not regarded as a defect.
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 25 first tests, 2.6 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.
Seat belts and restraints
One fault: seat belt condition (front), 5.7 times as often as on similar cars.
Seat belt condition (front)
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.
Steering
One fault: steering rack (front), 5.4 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.
Noise, emissions and leaks
Three faults. The strongest is the diesel emissions test (compression-ignition rules for vehicles from 01/07/2008): 2.9 times as often as on similar cars.
Diesel emissions test (compression-ignition rules for vehicles from 01/07/2008)
Diesel emissions test (pre-reg turbo rules before 01/07/2008)
Diesel engine warning light
What it means
An engine malfunction indicator lamp that is illuminated to show a malfunction is graded Major on a diesel, but only on the diesels the test covers, which depends on the vehicle type and when it was first used. DVSA lists it under exhaust emissions for compression ignition engines, and the detail line for the row also names an inoperative lamp.

Suspension
One fault: wheel bearings (front), 2.4 times as often as on similar cars.

MOT pass rates
How first tests ended, and how the pass rates are counted.
- Passed first time
- 50in every 100
- Passed on the first test.
- Fixed at the station
- 8in every 100
- Failed, then fixed at the test station the same day.
- Failed
- 42in every 100
- Did not pass, and were not fixed at the test station.
First-attempt pass 49.6% of 2,297 first tests (2025): only cars that passed first time count. Official-style pass 58.1%: cars fixed at the test station also count as a pass. The 8 fixed and the 42 not fixed make the 50 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, 49 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 matters most on a 2008 Partner.
Of 2008 Partner vehicles with under 72,000 miles, 60 in every 100 passed their 2025 MOT first time. With 156,000 miles or more, 46 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 72,000 | 101,000–125,000 | 156,000 and over | |
|---|---|---|---|
| Horn | 5.8 | 7.4 | 6.6 |
| Drive shaft joints and boots (front) | 6.9 | 7.0 | 5.5 |
| Brake light | 3.9 | 5.9 | 5.9 |
| Individual sidelight or tail light (front) | 1.3 | 7.2 | 7.5 |
| Coil spring (front) | 2.6 | 4.2 | 4.2 |

of failed cars had three or more items to fix.
of all first tests had a defect the tester marked dangerous (unsafe to drive away).
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.
