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 2018 Peugeot Expert 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.
Brakes
Three faults. The strongest is the brake pedal: 9.4 times as often as on similar cars.
Figures below are measured across the 1,306 failed first attempts in 2025 that had a mileage recorded, which allows a like-for-like comparison.
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.
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.
Handbrake performance (roller test, rear)
Handbrake efficiency below minimum (roller test)
What it means
A parking brake with efficiency below the minimum requirement is Major, and graded Dangerous where efficiency is less than half of the required value. On a roller brake tester, the requirement counts as met if more than half of the wheels of a brake system lock. The check applies only to vehicles whose parking brake was not already tested as the secondary brake.
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.
Body and structure
Two faults. The strongest is the exhaust system (front): 4.8 times as often as on similar cars.
Exhaust system (front)
What it means
Exhaust fumes causing a danger to health of persons on board are graded Dangerous, and so is a silencer likely to become detached. Fumes entering the cabin are Major. One or more missing or defective mountings does not necessarily make the exhaust insecure, since testers assess the overall security of the system.
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 42 first tests, 4.2 times as often as on similar cars.
Drive shaft joints and boots (front)
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage. Advisories count notes recorded on failed first tests only.
Lamps and electrical
Five faults. The strongest is the daytime running lights (front): 3.1 times as often as on similar cars.
Daytime running lights (front)
What it means
Daytime running lamps are inspected only when fitted as original equipment to cars and similar passenger vehicles first used on or after a set date. A lamp that is missing or not working, or that shows red light to the front, is Major. These lamps need not operate when the engine is not running, the parking brake is on, or park is selected on an automatic.
Individual sidelight or tail light (rear)
What it means
A position lamp showing red light to the front or white light to the rear is Major. Rear lamps must show a steady red light, and front ones can show white, predominantly white with a blue tinge, or yellow if combined in a yellow headlamp. With a multiple light source, up to half not working is Minor and more than half is Major.
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
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.
Brake light (rear)
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.

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.
Seat belt condition (front)
Transmission oil leaks
Engine oil leaks (front)
Individual direction indicators (rear)
Brake discs
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
- 71in 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
- 20in every 100
- Did not pass, and were not fixed at the test station.
First-attempt pass 71.4% of 4,569 first tests (2025): only cars that passed first time count. Official-style pass 79.7%: cars fixed at the test station also count as a pass. The 9 fixed and the 20 not fixed make the 29 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, 75 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 2018 Expert.
Of 2018 Expert vehicles with under 55,000 miles, 86 in every 100 passed their 2025 MOT first time. With 118,000 miles or more, 62 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 55,000 | 75,000–96,000 | 118,000 and over | |
|---|---|---|---|
| Drive shaft joints and boots (front) | 0.9 | 3.3 | 3.9 |
| Number plate lights | 1.0 | 2.5 | 4.9 |
| Headlight | 1.4 | 2.5 | 2.3 |
| Headlight aim | 1.0 | 2.2 | 2.5 |
| Brake pads (rear) | 0.7 | 1.8 | 3.0 |

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.
