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 2019 Peugeot Partner vehicles in 2025, not a prediction that any one car will have them. Faults are grouped by part of the car. A wear pattern follows age and use more than the way the car was built. They come from MOT defect codes, not manufacturer bulletins, recalls or a diagnosis of any one car.
Lamps and electrical
Four faults and one wear pattern. The strongest is the horn: 6.4 times as often as on similar cars.
Figures below are measured across the 3,206 of 3,210 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 (rear)
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 78 first tests, 5.9 times as often as on similar cars.
Number plate lights (rear)
What it means
Registration plate lamps must light up the rear registration plate and operate at the same time as the position lamps. A missing or inoperative lamp is Major when the plate has only one lamp or all its lamps are not working, and Minor when the plate has several lamps or light sources and not all have failed. A lamp throwing direct white light to the rear is also Minor.
Headlight aim not tested (front)
What it means
Headlamp aim recorded as not tested, or unable to be tested, is a Major failure. These results must only be used where it becomes apparent during the test that the item cannot be tested, and this could not have been identified before starting. The reason must be included in the additional information box.
Headlight (front)
What it means
On vehicles first used on or after a set date, a halogen headlamp unit converted to take HID or LED bulbs fails for light source and lamp not compatible, which is Major. A complete unit built with those light sources is not failed for that. The precise position of the lamps is not part of the inspection beyond a visual look to see that they sit at about the same height and distance from each side.
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
One fault: brake pedal, 6.2 times as often as on similar cars.
Brake pedal
What it means
A brake pedal rubber worn smooth is not a defect, and nor is a worn design pattern on an aftermarket rubber. A pedal with no rubber is rejected if its grooves or raised grip sections are worn smooth, unless the vehicle was made without them. Insufficient reserve travel is Major, but a vehicle is failed for it only if the pedal or lever is touching the floor or handlebar.
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.
Suspension
One fault: anti-roll bar linkage ball joint dust cover (front), 3.6 times as often as on similar cars.
Anti-roll bar linkage ball joint dust cover (front)
What it means
A suspension joint dust cover that is severely deteriorated is Minor. It becomes Major once it is missing or no longer prevents the ingress of dirt, so what matters is whether it still keeps dirt out. DVSA words this for any suspension joint dust cover, and files it here under anti-roll bars.

Body and structure
One fault: drive shaft joints and boots (front), 3.5 times as often as on similar cars.

Noise, emissions and leaks
One fault: diesel emissions test (compression-ignition rules for vehicles from 01/01/2014), 3.0 times as often as on similar cars.

Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.
Visibility
One fault: windscreen washers, 2.0 times as often as on similar cars.
Windscreen washers
What it means
Windscreen washers that are not working, or do not provide sufficient fluid to clear the windscreen, are graded Major. They must provide enough fluid for the wipers to clear the windscreen effectively. Vehicles with an opening windscreen, or some other adequate view to the front, left and right, are not inspected for washers.

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.

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
- 73in 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
- 19in every 100
- Did not pass, and were not fixed at the test station.
First-attempt pass 73.2% of 11,981 first tests (2025): only cars that passed first time count. Official-style pass 81.3%: cars fixed at the test station also count as a pass. The 8 fixed and the 19 not fixed make the 27 in every 100 that did not pass first time.
Petrol and diesel
Figures are in every 100 first tests.
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.

If you are buying one
What this year's MOT record means for the decision in front of you.
Mileage matters most on a 2019 Partner.
Of 2019 Partner vehicles with under 48,000 miles, 81 in every 100 passed their 2025 MOT first time. With 104,000 miles or more, 66 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 48,000 | 66,000–82,000 | 104,000 and over | |
|---|---|---|---|
| Number plate lights | 1.5 | 2.5 | 3.6 |
| Brake pads (rear) | 1.2 | 2.7 | 4.2 |
| Windscreen washers | 1.6 | 2.7 | 3.0 |
| Headlight aim | 1.5 | 2.9 | 2.5 |
| Drive shaft joints and boots (front) | 2.3 | 2.4 | 2.5 |

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.

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.
