Peugeot 108 common problems
The most common reason a Peugeot 108 fails its MOT is wiper blades that do not clear the screen, on 11.8% of its 14,460 failed tests in 2025. Against other cars of the same age, 4 faults stand out, the widest gaps being: a weak or uneven footbrake at 6.2% of failures against 1.8% expected; a weak handbrake at 5.4% of failures against 2.3% expected; worn brake discs at 4.8% of failures against 2.3% expected.

What fails a Peugeot 108 MOT
Each bar is the share of failed Peugeot 108 tests with that defect. Where we can compare it with cars of the same registration years, the marker shows what an average car of those ages records (12 of the 12 items below).
Most common reasons for failure
A test can fail for more than one defect, so shares add up to more than 100%.
| Defect | Share of failed tests |
|---|---|
| Wipers: does not clear the windscreen effectively Visibility | 11.8% |
| Tyres: tread depth below requirements of 1.6mm Tyres | 9.5% |
| Brake pads: less than 1.5 mm thick Brakes | 9.1% |
| Malfunction indicator lamp: inoperative or indicates a malfunction Noise, emissions and leaks | 7.1% |
| Service brake performance: excessively binding Brakes | 6.2% |
| Tyres: ply or cords exposed Tyres | 5.8% |
| Washers: provides insufficient washer liquid Visibility | 5.5% |
| Parking brake efficiency below requirements Brakes | 5.4% |
| Tyres: cut in excess of the requirements deep enough to reach the ply or cords Tyres | 5.0% |
| Brake discs: significantly and obviously worn Brakes | 4.8% |
| Headlamp: not working on dipped beam Lamps, reflectors and electrical equipment | 4.8% |
| Headlamp aim: too low Lamps, reflectors and electrical equipment | 4.6% |

-
Wiper blades that do not clear the screen
11.8% of failures 7.1% expected 1.7 times as often
Wiper blades that leave the windscreen smeared or streaked across the area the driver looks through.
Look for split or hardened rubber, and lift each blade to see whether it still sits flat.
-
Tyre worn below the legal limit
9.5% of failures 9.4% expected about as expected
A tyre worn past the 1.6mm legal minimum across the middle three quarters of the tread.
A 20p coin in the main grooves: if the outer band of the coin is visible, the tyre is close to the limit.
-
Worn brake pads
9.1% of failures 8.2% expected about as expected
Friction material worn under 1.5mm, thinner than the point most manufacturers call the limit.
Look through the wheel spokes at the pad against the disc; wear indicators squeal before they get this far.
-
Engine management light on
7.1% of failures 5.4% expected somewhat more often
The engine management light is on, or has been disconnected. Either fails the test.
A cheap code reader on the diagnostic socket will say what the car has stored before you pay for a test.
-
Weak or uneven footbrake
6.2% of failures 1.8% expected 3.4 times as often
The footbrake is either weak overall or pulls unevenly across an axle, which the rolling road measures.
A pull to one side under firm braking, or a long pedal, is the sign to get it looked at before a test.
-
Tyre worn through to the cords
5.8% of failures 5.2% expected about as expected
The tyre is worn or damaged far enough to expose the cords underneath, which is a dangerous defect.
Run a hand round the inner and outer walls of each tyre, which is where kerbing shows.
Which parts of the car fail
Brakes is the area that most often fails a Peugeot 108, on 31.2% of failed tests. That is also where it differs most from cars of the same registration years, which record 19.4%.

What testers warn about
50.0% of Peugeot 108 tests ended with at least one advisory: a fault the tester found that did not fail the test. On Peugeot 108s, these are the items to ask about on a car you are viewing, because they are what the last tester expected to go next.
Most common advisories
Share of all tests, passes included.
| Advisory | Share of tests |
|---|---|
| Tyres: slightly damaged or cracking or perishing Tyres | 16.7% |
| Tread depth: worn close to legal limit or worn on edge Tyres | 14.5% |
| Brake discs: worn, pitted or scored, but not seriously weakened Brakes | 11.2% |
| Linkage pins and bushes: pin or bush worn but not resulting in excessive movement Suspension | 7.3% |
| Brake pads: wearing thin Brakes | 5.2% |
| Suspension arms: pin or bush worn but not resulting in excessive movement Suspension | 4.1% |
| Rigid brake pipes: corroded, covered in grease or other material Brakes | 3.1% |
| Brake discs: worn, but not excessively Brakes | 2.9% |
| Road wheels: slightly distorted Road wheels | 2.7% |
| Sub-frame: corroded but not seriously weakened Suspension | 2.4% |
| Service brake performance: binding but not excessively Brakes | 2.2% |
| Coil spring: corroded Suspension | 1.8% |

What changes as a Peugeot 108 gets older
A 2021 Peugeot 108 failed 10.2% of its MOT tests in 2025; a 2014 one failed 25.5%. What fails changes as much as how often, and these are the two years themselves rather than an average across them.
2021 Peugeot 108 10.2% failed, from 4,118 tests
- Wiper blades that do not clear the screen 19.2%
- Bulge in a tyre 13.3%
- Worn brake pads 12.1%
- Tyre worn below the legal limit 8.3%
- Headlamp aim set too low 8.1%
- Worn brake discs 5.5%
2014 Peugeot 108 25.5% failed, from 7,067 tests
- Weak or uneven footbrake 11.0%
- Engine management light on 10.7%
- Tyre worn below the legal limit 8.1%
- Weak handbrake 7.5%
- Wiper blades that do not clear the screen 7.0%
- Linkage pins and bushes pin or bush worn 6.7%

Peugeot 108 problems: common questions
What is the most common problem with a Peugeot 108?
Of the faults that fail an MOT, “Wipers: does not clear the windscreen effectively” is the most common: it appears on 11.8% of failed Peugeot 108 tests. Across categories, brakes is the area that most often fails one, on 31.2% of failed tests.
How often does a Peugeot 108 fail its MOT?
18.8% of Peugeot 108 tests in 2025 were not passed first time, from 77,108 tests of cars aged three and over. Allowing for the age and mileage of the cars tested, that gives it a UK Motoring Reliability Score of 51 out of 100, where 50 is as expected.
Does anything fail more often on a Peugeot 108 than on other cars?
Yes. “Service brake performance: excessively binding” appears on 6.2% of its failures against 1.8% for cars of the same age, and “Parking brake efficiency below requirements” appears on 5.4% of its failures against 2.3% for cars of the same age. Where an item is missing from the national figures for a year, we use the smallest share those figures show, so the comparison never overstates the difference.
Are these the same as breakdowns or known faults?
No. These are the items a tester recorded at the MOT, which covers condition and safety: lamps, brakes, tyres, suspension, corrosion and emissions. A gearbox that is unpleasant, an infotainment screen that has died, or a car that will not start on a cold morning are not part of the test, so they are not in these figures.
Where do the figures come from?
Every normal MOT test of a Peugeot 108 aged three and over in Great Britain in 2025, from DVSA's anonymised MOT results. Retests are excluded, and the same fault on more than one wheel counts once.

Data sources and methodology
| Figures | Source | Period | Records | Updated |

- Shares for defects are of failed tests; shares for advisories are of all tests. A test can carry several defects, so shares add to more than 100%.
- The expected share is what an average car of the same registration years records, weighted by where this model’s failures fall. Where an item is outside the national figures for a year, the smallest share those figures show is used in its place, which is an upper bound, so the comparison never overstates a model’s problems. No expectation is published where less than 80% of the model’s failures can be compared.
- Great Britain only: DVSA does not run MOT testing in Northern Ireland. Cars under three years old are not tested.
- The descriptions of what each part does are general and the same on every model. Every figure comes from the MOT data.
