Peugeot 107 2009: reliability & common MOT faults

In 2025, 57 in every 100 first MOTs on a 2009 Peugeot 107 were passes. Most common reason for a fail: Brake performance (roller test, rear).

Summary

The 2009 Peugeot 107 follows the pattern of the model years either side.

What failed most often

  1. Brake performance (roller test, rear)16 in every 100 failed tests
  2. Individual sidelight or tail light (front)14 in every 100 failed tests
  3. Suspension mounting area (rear)10 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 2009 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.

Suspension

Three faults. The strongest is the anti-roll bar linkage pins and bushes (front): 15 times as often as on similar cars.

Figures below are measured across the 5,049 of 5,052 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 156 first tests15 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 582 first tests, 26 times as often as on similar cars.

Suspension mounting area (rear)

Failed on 496 first tests4.1 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.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 222 first tests, 2.6 times as often as on similar cars.

Wheel bearings (front)

Failed on 203 first tests3.9 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 101 first tests, 2.4 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

Four faults. The strongest is the brake performance (plate test, rear): 5.6 times as often as on similar cars.

Brake performance (plate test, rear)

Failed on 185 first tests5.6 times as often as similar carsStrong 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.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 85 first tests, 2.6 times as often as on similar cars.

Brake performance (roller test, rear)

Failed on 786 first tests5.0 times as often as similar carsStrong 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 334 first tests, 2.4 times as often as on similar cars.

Rigid brake pipes (rear)

Failed on 336 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 934 first tests, 3.9 times as often as on similar cars.

Brake imbalance across an axle (roller test, efficiency check, rear)

Failed on 162 first tests2.4 times as often as similar carsPossible evidence

What it means

A wheel giving less than a set share of the maximum effort from the other wheel on the same axle is Major. On a steered axle, less than half is graded Dangerous. Testers disregard an imbalance if the lower effort is the result of a locked wheel, or if the higher effort from a wheel is at or below a low set figure.

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

Two faults. The strongest is the chassis condition (rear): 3.8 times as often as on similar cars.

Chassis condition (rear)

Failed on 114 first tests3.8 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 (rear)

Failed on 263 first tests2.9 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.

Lamps and electrical

One fault: horn, 2.2 times as often as on similar cars.

Horn

Failed on 118 first tests2.2 times as often as similar carsPossible 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.

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.

Anti-roll bar pins and bushes (front)

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.

The 2009 Peugeot 107 follows the pattern of the model years either side. Its main cause of failure was Brake performance (roller test, rear), about 16 in every 100 failed tests. In 2025, 56.6% of 11,648 first MOTs on the 2009 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 64.8%. Among 5,052 failed first-attempt MOT tests (test year 2025), Anti-roll bar linkage pins and bushes (front) appears more often than on similar cars (3.1% of those tests; 156 observed failures; about 15× 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 2009 Peugeot 107 at the first attempt were Brake performance (roller test, rear) (15.6%), Individual sidelight or tail light (front) (14.3%) and Suspension mounting area (rear) (9.8%), 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) (3.1% of those tests; 156 observed failures; about 15× 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 (3.1% of those tests; 156 observed failures; about 15× 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 2009 Peugeot 107 include Anti-roll bar linkage pins and bushes (front), Brake performance (plate test, rear), 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 2009 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.
