Peugeot 108 2014: reliability & common MOT faults

In 2025, 74 in every 100 first MOTs on a 2014 Peugeot 108 were passes. Most common reason for a fail: Petrol engine warning light.

Summary

A 2014 Peugeot 108 passed first time about 3 in every 100 less often than the 2015 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 108 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.

Suspension

Two faults. The strongest is the anti-roll bar linkage pins and bushes (front): 32 times as often as on similar cars.

Figures below are measured across the 1,755 of 1,757 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.

Anti-roll bar linkage pins and bushes (front)

Failed on 121 first tests32 times as often as similar carsStrong 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 245 first tests, 33 times as often as on similar cars.

Wheel bearings (front)

Failed on 72 first tests6.4 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, 2.7 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.

Brakes

Five faults and one wear pattern. The strongest is the handbrake lever: 5.3 times as often as on similar cars.

Handbrake lever

Failed on 61 first tests5.3 times as often as similar carsLikely evidence

What it means

A parking brake lever pivot or ratchet mechanism that is obviously worn is graded Minor. It is Major when worn to the extent that the brake may inadvertently release, and also when the ratchet is not holding correctly. A lever must have obvious excessive travel before being rejected.

Brake performance (plate test, rear)

Failed on 40 first tests4.7 times as often as similar carsLikely evidence

What it means

Braking effort that is inadequate at a wheel, a brake grabbing severely and a binding brake are among the Major failures. A wheel with no recorded effort is graded Dangerous. If a vehicle fails any aspect of the plate test, the check should be repeated to confirm the result.

Brake performance (roller test, rear)

Failed on 147 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.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 75 first tests, 2.1 times as often as on similar cars.

Handbrake performance (roller test, rear)

Failed on 41 first tests3.4 times as often as similar carsLikely evidence

What it means

A parking brake that is inoperative on one side is Major. When tested on the road, the failure is the vehicle deviating excessively from a straight line. Vehicles whose parking brake was already tested as the secondary brake are not tested again for this.

Electronic stability control

Failed on 43 first tests3.1 times as often as similar carsLikely evidence

What it means

An ESC warning lamp is failed only when the tester is certain it indicates an ESC malfunction, because the lamp takes various forms and the owner's handbook may need checking. The system is also called ESP, VDC or DSC, among many other names. Every failure row is Major, covering the lamp, wheel speed sensors, wiring, other components and the switch.

Brake discs (front)

Failed on 101 first tests2.9 times as often as similar carsWear pattern

What it means

A brake disc or drum must be significantly worn before it is rejected, and being worn below the manufacturer's recommended limits is not a reason in itself. Significantly and obviously worn is Major, as is contamination with oil or grease. A disc or drum that is fractured, insecure, seriously weakened or missing is graded Dangerous.

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 engine warning light: 3.9 times as often as on similar cars.

Petrol engine warning light

Failed on 180 first tests3.9 times as often as similar carsLikely evidence

What it means

The malfunction indicator lamp (MIL) on a petrol engine is a Major failure when it is illuminated indicating a malfunction. The detail line DVSA gives for the same row also names an inoperative lamp. The test covers only certain petrol vehicles, depending on their age, size and fuel type.

Petrol emissions (with catalyst)

Failed on 145 first tests3.1 times as often as similar carsLikely 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.

Body and structure

One fault: exhaust system (front), 2.8 times as often as on similar cars.

Exhaust system (front)

Failed on 39 first tests2.8 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.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 51 first tests, 2.3 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.

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 108 passed first time about 3 in every 100 less often than the 2015 model year next to it. In 2025, 74.3% of 6,827 first MOTs on the 2014 Peugeot 108 passed first time (PRS: items fixed at the station the same day, counted as a fail). The official-style rate including PRS is 78.7%. Among 1,757 failed first-attempt MOT tests (test year 2025), Anti-roll bar linkage pins and bushes (front) appears more often than on similar cars (6.9% of those tests; 121 observed failures; about 32× 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 108 at the first attempt were Petrol engine warning light (10.3%), Tyre condition (front) (10.1%) and Handbrake efficiency below minimum (roller test) (8.5%), 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: Anti-roll bar linkage pins and bushes (front) (6.9% of those tests; 121 observed failures; about 32× more often than similar cars). These are statistical signals, not a diagnosis of any individual car.
Anti-roll bar linkage pins and bushes (front) shows up more often than on similar cars (6.9% of those tests; 121 observed failures; about 32× 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 108 include Anti-roll bar linkage pins and bushes (front), Wheel bearings (front), Handbrake lever. 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 108 (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.
