Known faults, from the test record
Peugeot Boxer common problems
What fails on the Peugeot Boxer at MOT, which parts are behind it, and how each model year compares. From 54,709 DVSA test records.
Data updated
Quick answer
The Peugeot Boxer's most common MOT problems are bulbs and lamps, suspension arms and mountings, body and structure, recorded in 36.2%, 24.7% and 21.2% of failed tests respectively. By model year, 2020 cars pass most often (83.5%) and 1998 cars least (56.2%), though most of that gap is age. Every figure here is what testers recorded, not what owners reported.
A “common problems” list is usually a forum thread: whoever had the worst day writes the longest post. This one is built the other way, from every Peugeot Boxer that took an MOT last year and what the tester wrote down. It cannot see breakdowns, electrical gremlins or a gearbox that hunts, because the test does not check those. What it can see, it sees across 54,709 cars.
By component
What wears out on a Boxer
Failure items grouped by the part behind them, with the share of failed Peugeot Boxer tests recording each. A part can carry several DVSA wordings; they are listed beneath. One failed test often lists several items, so shares do not sum to 100%.
1.Bulbs and lamps
36.2% of failed testsFilament bulbs simply expire; the cheapest and most avoidable failure on the test, and one of the most recorded.
- “A lamp missing, inoperative or in the case of a multiple light source more than 1/2 not functioning” — explained7.8%
- “A lamp missing, inoperative or in the case of a multiple light source more than 1/2 not functioning” — explained4.9%
- “Stop lamp missing, inoperative or in the case of a multiple light source more than 1/2 not functioning” — explained4.7%
- “An obligatory rear fog lamp missing, or a front or rear fog lamp inoperative or in the case of a multiple light source more than 1/2 not functioning” — explained4.6%
Across all cars, bulbs and lamps failures climb 15-fold between three and fifteen years, peaking at 15+ years. How long bulbs and lamps last
2.Suspension arms and mountings
24.7% of failed testsArms bend on impact and mountings corrode into the body; a corroded mounting is a structural item and fails as one.
- “The strength or continuity of the load bearing structure within 30cm of any sub-frame, spring or suspension component mounting (a 'prescribed area') is significantly reduced or inadequately repaired” — explained20.1%
- “The strength or continuity of the load bearing structure within 30cm of any sub-frame, spring or suspension component mounting (a 'prescribed area') is significantly reduced or inadequately repaired” — explained4.6%
3.Body and structure
21.2% of failed testsStructural corrosion within 30 cm of a seat belt, suspension or steering mounting fails; it is a disease of age, salt and wet storage.
- “Vehicle structure corroded to the extent that the rigidity of the assembly is seriously reduced” — explained10.2%
- “Body, cab or chassis excessively corroded at a mounting point” — explained5.8%
- “Vehicle structure corroded to the extent that the rigidity of the assembly is seriously reduced” — explained5.2%
4.Wiper blades and washers
20.0% of failed testsRubber blades harden and split within a year or two; washer jets block and pumps fail.
- “Wiper blade missing or obviously not clearing the windscreen” — explained11.8%
- “Windscreen washers not working or not providing sufficient fluid to clear the windscreen” — explained4.4%
- “Windscreen washers not working or not providing sufficient fluid to clear the windscreen” — explained3.8%
Across all cars, wiper blades and washers failures run at a similar rate at every age, because they are replaced on a cycle rather than wearing out with the car. How long wiper blades and washers last
5.Parking brake
14.2% of failed testsCables stretch and seize, rear shoes and adjusters wear; efficiency is measured on the roller tester against the vehicle's weight.
6.Headlamp aim
11.9% of failed testsAim drifts with sagging suspension, a knocked lamp or a botched bulb change; adjustment, not a part.
7.Brake callipers
11.8% of failed testsPistons and slider pins seize with corrosion and disuse, dragging a brake on or leaving one side weak; shows as imbalance on the roller tester.
8.Tyres
8.8% of failed testsTread wears with every mile and sidewalls age and take kerb damage; the legal minimum is 1.6 mm across the central three-quarters.
- “A tyre seriously damaged” — explained3.5%
- “A tyre seriously damaged” — explained3.0%
- “Tyre tread depth not in accordance with the requirements” — explained2.3%
Across all cars, tyres failures run at a similar rate at every age, because they are replaced on a cycle rather than wearing out with the car. How long tyres last
By registration year
Boxer problems by year
MOT pass rate for Peugeot Boxer cars by the year they were first registered, from years with at least 1,000 tests. Every car in a row is the same age, so the rate is raw. Neighbouring years differ by a year of wear — a step of a point or two is age. The step at 2003, up 6.8 points, is larger than wear explains and most likely marks a change in the cars themselves.
Last column: change on the previous year, in points. Years registered within the last three years have not yet been tested and are not shown.

Common questions
- What are the most common problems with a Peugeot Boxer?
- Going by what fails the MOT, bulbs and lamps (recorded in 36.2% of failed tests), suspension arms and mountings (recorded in 24.7% of failed tests), and body and structure (recorded in 21.2% of failed tests). These are the items testers actually record across 54,709 tests, not reports from owners, so they describe what goes wrong at the point where it has to be fixed.
- Which Peugeot Boxer year is the most reliable?
- By MOT pass rate, Peugeot Boxer cars registered in 2020 do best at 83.5% and 1998 cars do worst at 56.2%. Most of that ordering is simply age — newer cars pass more — so read the year table for steps larger than a couple of points between neighbouring years; those mark a change in the cars rather than the calendar. The largest such step is at 2003, up 6.8 points on 2002.
- Is the Peugeot Boxer reliable?
- Adjusted for the age and mileage of the cars tested, the Peugeot Boxer passes 71.4% of MOTs against a national 72.3%. An MOT measures roadworthiness on the day rather than breakdowns or running costs, so this is a reliability measure in the narrow sense: how often the car meets the legal standard, and what stops it.
- What should I check when buying a used Peugeot Boxer?
- Start with what fails most: bulbs and lamps, wiper blades and washers, tyres. Then read the car's own MOT history for advisories carried year to year without repair — the model tells you what to expect, the history tells you whether this owner dealt with it.
