Peugeot Boxer 2015: reliability & common MOT faults

In 2025, 77 in every 100 first MOTs on a 2015 Peugeot Boxer were passes. Most common reason for a fail: Handbrake efficiency below minimum (roller test).

Summary

The 2015 Peugeot Boxer follows the pattern of the model years either side.

  2. Headlight aim8 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 2015 Peugeot Boxer 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.

Seat belts and restraints

One fault: airbag warning light, 5.8 times as often as on similar cars.

Figures below are measured across the 671 of 676 failed first attempts (99.3%) 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.

Airbag warning light

Failed on 44 first tests5.8 times as often as similar carsLikely evidence

What it means

The airbag warning lamp (SRS MIL in DVSA's wording) is failed only if it indicates a system malfunction, which is Major. A lamp lit to show the passenger airbag is disabled is not to be regarded as a defect. Dashboard messages are not a defect in their own right, though they can help the tester confirm a malfunction.

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

Brakes

Two faults. The strongest is the handbrake efficiency below minimum (roller test): 3.7 times as often as on similar cars.

Handbrake efficiency below minimum (roller test)

Failed on 90 first tests3.7 times as often as similar carsLikely evidence

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.

Brake performance (roller test, rear)

Failed on 28 first tests2.1 times as often as similar carsPossible 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.

Suspension

One fault: shock absorbers (front), 3.1 times as often as on similar cars.

Shock absorbers (front)

Failed on 39 first tests3.1 times as often as similar carsLikely evidence

What it means

Slight seepage that leaves a film of fluid on a shock absorber does not fail it. Severe leakage, or damage so that it does not function, is Major. A shock absorber missing or likely to become detached is graded Dangerous, though a missing one is only rejected if shock absorbers were fitted as standard.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 47 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.

Noise, emissions and leaks

One fault: diesel emissions test (compression-ignition rules for vehicles from 01/01/2014), 2.9 times as often as on similar cars.

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.

FAQs

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

The 2015 Peugeot Boxer follows the pattern of the model years either side. Its main cause of failure was Handbrake efficiency below minimum (roller test), about 13 in every 100 failed tests. In 2025, 77.4% of 2,996 first MOTs on the 2015 Peugeot Boxer passed first time (PRS: items fixed at the station the same day, counted as a fail). The official-style rate including PRS is 82.3%. Among 676 failed first-attempt MOT tests (test year 2025), Airbag warning light appears more often than on similar cars (6.6% of those tests; 44 observed failures; about 5.8× 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 2015 Peugeot Boxer at the first attempt were Handbrake efficiency below minimum (roller test) (13.4%) and Headlight aim (7.6%), 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: Airbag warning light (6.6% of those tests; 44 observed failures; about 5.8× more often than similar cars). These are statistical signals, not a diagnosis of any individual car.
Airbag warning light shows up more often than on similar cars (6.6% of those tests; 44 observed failures; about 5.8× 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 2015 Peugeot Boxer include Airbag warning light, Handbrake efficiency below minimum (roller test), Shock absorbers (front). 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 2015 Peugeot Boxer (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.
