Peugeot 107 2014: reliability & common MOT faults

In 2025, 73 in every 100 first MOTs on a 2014 Peugeot 107 were passes. Most common reason for a fail: Individual sidelight or tail light (front).

Summary

A 2014 Peugeot 107 passed first time about 5 in every 100 more often than the 2013 model year next to it.

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 2014 Peugeot 107 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

Two faults and one wear pattern. The strongest is the hazard warning switch: 39 times as often as on similar cars.

Figures below are measured across the 2,229 of 2,230 failed first attempts 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.

Hazard warning switch

Failed on 137 first tests39 times as often as similar carsStrong 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.

Individual sidelight or tail light (front)

Failed on 234 first tests2.2 times as often as similar carsPossible evidence

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.

Headlight aim (front)

Failed on 180 first tests2.0 times as often as similar carsWear pattern

What it means

Beam aim too high, too low or off to either side is Major. Where a driver's beam aim control is fitted, the aim is tested without altering the setting, and rechecked at the highest setting only if it would fail for being too low. Masks or converter kits on right hand dip headlamps are acceptable.

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): 14 times as often as on similar cars.

Anti-roll bar linkage pins and bushes (front)

Failed on 69 first tests14 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 249 first tests, 27 times as often as on similar cars.

Wheel bearings (rear)

Failed on 45 first tests5.4 times as often as similar carsLikely 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.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 21 first tests, 4.0 times as often as on similar cars.

Wheel bearings (front)

Failed on 51 first tests3.5 times as often as similar carsLikely 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: rigid brake pipes (rear), 3.7 times as often as on similar cars.

Rigid brake pipes (rear)

Failed on 74 first tests3.7 times as often as similar carsLikely evidence

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 223 first tests, 3.9 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.

Body and structure

One fault: exhaust system (rear), 3.1 times as often as on similar cars.

Exhaust system (rear)

Failed on 62 first tests3.1 times as often as similar carsLikely 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.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 83 first tests, 3.1 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.

Noise, emissions and leaks

Two faults. The strongest is the petrol emissions not tested: 3.0 times as often as on similar cars.

Petrol emissions not tested

Failed on 54 first tests3.0 times as often as similar carsLikely 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 133 first tests2.3 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.

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.

FAQs

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

A 2014 Peugeot 107 passed first time about 5 in every 100 more often than the 2013 model year next to it. In 2025, 73.2% of 8,333 first MOTs on the 2014 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 80.1%. Among 2,230 failed first-attempt MOT tests (test year 2025), Hazard warning switch appears more often than on similar cars (6.1% of those tests; 137 observed failures; about 39× 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 2014 Peugeot 107 at the first attempt were Individual sidelight or tail light (front) (10.5%), Headlight aim (10.4%) and Tyre tread depth (front) (8.7%), 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 (6.1% of those tests; 137 observed failures; about 39× 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 (6.1% of those tests; 137 observed failures; about 39× 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 2014 Peugeot 107 include Hazard warning switch, Anti-roll bar linkage pins and bushes (front), Wheel bearings (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 2014 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.
