  2. Suspension mounting area (rear)16 in every 100 failed tests
  3. Individual sidelight or tail light (front)14 in every 100 failed tests

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.

Note:

These are patterns across 2005 Peugeot 107 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

Two faults. The strongest is the hazard warning switch: 14 times as often as on similar cars.

Figures below are measured across the 772 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.

Hazard warning switch

Failed on 29 first tests14 times as often as similar carsPossible evidence

What it means

A hazard warning switch that is inoperative is Major, while one that is faulty or insecure is Minor. The lamps must work from one switch only, with the engine or ignition switch both on and off.

Horn

Failed on 32 first tests3.1 times as often as similar carsLikely evidence

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.

Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.

Suspension

Three faults. The strongest is the anti-roll bar linkage pins and bushes (front): 6.0 times as often as on similar cars.

Anti-roll bar linkage pins and bushes (front)

Failed on 34 first tests6.0 times as often as similar carsLikely evidence

What it means

Excessive wear in an anti-roll bar linkage pin or bush is Major. If the pin or bush is likely to become detached, it is graded Dangerous. The wording is DVSA's general one 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 100 first tests, 9.6 times as often as on similar cars.

Suspension mounting area (rear)

Failed on 122 first tests3.3 times as often as similar carsLikely evidence

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.

Wheel bearings (front)

Failed on 32 first tests2.6 times as often as similar carsPossible evidence

What it means

Excessive play in a wheel bearing, or a bearing that is excessively rough, is Major. Play so excessive that the bearing is likely to break up or directional control is impaired is Dangerous, and so is a bearing so rough that it is likely to overheat or break up.

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 performance (roller test, rear), 3.5 times as often as on similar cars.

Brake performance (roller test, rear)

Failed on 76 first tests3.5 times as often as similar carsLikely evidence

What it means

A wheel with no recorded braking effort on the roller test is graded Dangerous. Inadequate effort, a brake grabbing severely, abnormal lag and excessive fluctuation in effort are each Major. So is significant brake effort recorded with no brake applied, which indicates a binding 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 chassis condition (rear): 3.5 times as often as on similar cars.

Chassis condition (rear)

Failed on 36 first tests3.5 times as often as similar carsLikely evidence

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.

Exhaust system

Failed on 48 first tests2.2 times as often as similar carsPossible evidence

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.

Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.

Noise, emissions and leaks

Two faults. The strongest is the petrol emissions not tested: 2.1 times as often as on similar cars.

Petrol emissions not tested

Failed on 34 first tests2.1 times as often as similar carsPossible evidence

What it means

On a petrol car, an emissions test recorded as not tested or unable to be completed is failed as Major. DVSA's wording gives no reason why.

Petrol emissions (with catalyst)

Failed on 87 first tests2.0 times as often as similar carsPossible evidence

What it means

Emissions levels over the manufacturer's specified limits are Major, as are levels over default limits, which apply when no exact match is found for the vehicle. Dense blue or clearly visible black smoke at idle, held for a set period, is Major, except for certain older vehicles and two stroke engines where smoke is unavoidable. An induction or exhaust leak that could affect emissions levels is Major too.

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.

MOT pass rates

How first tests ended, and how the pass rates are counted.

Passed first time
52in 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
40in every 100
Did not pass, and were not fixed at the test station.

First-attempt pass 51.6% of 1,594 first tests (2025): only cars that passed first time count. Official-style pass 60.5%: cars fixed at the test station also count as a pass. The 8 fixed and the 40 not fixed make the 48 in every 100 that did not pass first time.

Same model, other years

FAQs

Short answers about how to read this model-year guide.

The 2005 Peugeot 107 follows the pattern of the model years either side. Its main cause of failure was Headlight aim, about 17 in every 100 failed tests. In 2025, 51.6% of 1,594 first MOTs on the 2005 Peugeot 107 passed first time (PRS: items fixed at the station the same day, counted as a fail). The official-style rate including PRS is 60.5%. Among 772 failed first-attempt MOT tests (test year 2025), Hazard warning switch appears more often than on similar cars (3.8% of those tests; 29 observed failures; about 14× more often than similar cars). There is no single reliability score here; this is a pre-purchase checklist built from DVSA open data, not a guarantee for any individual car.
Ranked by how often they were actually recorded, the items that most often failed a 2005 Peugeot 107 at the first attempt were Headlight aim (17.1%), Suspension mounting area (rear) (15.8%) and Individual sidelight or tail light (front) (14.1%), each as a share of the year's failed first attempts. That is what goes wrong most often on the car. The common faults table shows a different measure: faults that are unusual compared with similar cars.
Among failed first-attempt tests we highlight patterns that appear more often than on similar cars. Top example: Hazard warning switch (3.8% of those tests; 29 observed failures; about 14× more often than similar cars). These are statistical signals, not a diagnosis of any individual car.
Hazard warning switch shows up more often than on similar cars (3.8% of those tests; 29 observed failures; about 14× more often than similar cars). That does not prove a design fault. Age, mileage, and how the car was used still matter. Treat it as a pre-purchase checkpoint, not a manufacturer service bulletin.
Common MOT problem areas for the 2005 Peugeot 107 include Hazard warning switch, Anti-roll bar linkage pins and bushes (front), Brake performance (roller test, rear). These are the faults that stand out compared with similar cars, not a complete list of what can go wrong on any individual car.
Advisories flag issues noted at the test and are not a fail rate. We show advisory patterns that appear more often than on similar cars among failed first-attempt tests, separate from common failure rows. Use them as early-warning checks, not as a pass/fail score.
This page highlights MOT failure patterns for the 2005 Peugeot 107 (registration year) using UK DVSA open data for the selected test year. Patterns are compared with cars of a similar age and mileage. It is a buyer checklist from MOT defect statistics, not a full service history or manufacturer service-bulletin list.
No. MOT tests do not cover engine internals, gearboxes, or many electronic modules. Patterns here come from MOT defect statistics only and should not be read as engine or gearbox reliability scores.

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.

2024 2025

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.
