Peugeot 106 common problems
The most common reason a Peugeot 106 fails its MOT is emissions above the limit, on 14.7% of its 1,780 failed tests in 2025. Against other cars of the same age, 6 faults stand out, the widest gaps being: a weak or uneven footbrake at 12.8% of failures against 2.6% expected; a steering fault at 8.3% of failures against 2.5% expected; emissions above the limit at 11.5% of failures against 4.5% expected.

What fails a Peugeot 106 MOT
Each bar is the share of failed Peugeot 106 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 |
|---|---|
| Catalyst emissions: lambda reading after 2nd fast idle outside specified limits Noise, emissions and leaks | 14.7% |
| Drive shafts: constant velocity boot split or insecure, no longer prevents the ingress of dirt Body, chassis, structure | 13.2% |
| Service brake imbalance: across an axle Brakes | 13.1% |
| Service brake performance: efficiency below requirements Brakes | 12.8% |
| Stop lamp: not working Lamps, reflectors and electrical equipment | 12.1% |
| Catalyst emissions: carbon monoxide content after 2nd fast idle exceeds manufacturer's specified limits Noise, emissions and leaks | 11.5% |
| Component mounting prescribed area excessively corroded significantly reducing structural strength Suspension | 11.5% |
| Position lamp: not working Lamps, reflectors and electrical equipment | 9.3% |
| Exhaust system: major leak of exhaust gases Body, chassis, structure | 8.3% |
| Steering rack: gaiter missing or no longer prevents the ingress of dirt Steering | 8.3% |
| Wipers: does not clear the windscreen effectively Visibility | 7.6% |
| Parking brake efficiency below requirements Brakes | 6.7% |

-
Emissions above the limit
14.7% of failures 6.8% expected 2.2 times as often
The exhaust gases are outside the limits for the car, which can be the catalytic converter, a sensor, or simply a poor state of tune.
A long run before the test helps a catalyst get hot; a persistent failure usually needs a diagnosis.
-
Split joint boot
13.2% of failures 6.3% expected 2.1 times as often
A split rubber boot on a joint or driveshaft. The joint may still be sound, but dirt and water get in once the boot is open.
Turn the wheels to full lock and look behind them for greasy splits in the rubber concertina.
-
Weak or uneven footbrake
13.1% of failures 4.3% expected 3 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.
-
Weak or uneven footbrake
12.8% of failures 2.6% expected 4.9 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.
-
Brake light out
12.1% of failures 8.0% expected 1.5 times as often
A brake light not working, from a bulb, a poor earth, or the switch on the pedal.
Reverse up to a wall or window at dusk and press the pedal to see all three lamps light.
-
Emissions above the limit
11.5% of failures 4.5% expected 2.6 times as often
The exhaust gases are outside the limits for the car, which can be the catalytic converter, a sensor, or simply a poor state of tune.
A long run before the test helps a catalyst get hot; a persistent failure usually needs a diagnosis.
Which parts of the car fail
Lamps, reflectors and electrical equipment is the area that most often fails a Peugeot 106, on 40.0% of failed tests. The widest gap against cars of the same registration years is noise, emissions and leaks, on 35.2% against 21.0% expected.

What testers warn about
57.6% of Peugeot 106 tests ended with at least one advisory: a fault the tester found that did not fail the test. On Peugeot 106s, 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 |
|---|---|
| Engine oil leak, but not excessive Noise, emissions and leaks | 17.6% |
| Tyres: slightly damaged or cracking or perishing Tyres | 12.7% |
| Tread depth: worn close to legal limit or worn on edge Tyres | 10.9% |
| Rigid brake pipes: corroded, covered in grease or other material Brakes | 8.3% |
| Exhaust system: minor leak of exhaust gases Body, chassis, structure | 7.2% |
| Brake discs: worn, pitted or scored, but not seriously weakened Brakes | 6.3% |
| Registration plates: deteriorated but not likely to be misread Identification of the vehicle | 5.1% |
| Component mounting prescribed area is corroded but not considered excessive Suspension | 4.4% |
| Suspension arms: ball joint has slight play Suspension | 3.4% |
| Coil spring: corroded Suspension | 2.8% |
| Suspension arms: pin or bush worn but not resulting in excessive movement Suspension | 2.7% |
| Integral vehicle structure condition: corroded but structural rigidity is not significantly reduced Body, chassis, structure | 2.1% |

Peugeot 106 problems: common questions
What is the most common problem with a Peugeot 106?
Of the faults that fail an MOT, “Catalyst emissions: lambda reading after 2nd fast idle outside specified limits” is the most common: it appears on 14.7% of failed Peugeot 106 tests. Across categories, lamps, reflectors and electrical equipment is the area that most often fails one, on 40.0% of failed tests.
How often does a Peugeot 106 fail its MOT?
42.6% of Peugeot 106 tests in 2025 were not passed first time, from 4,178 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 47 out of 100, where 50 is as expected.
Does anything fail more often on a Peugeot 106 than on other cars?
Yes. “Service brake performance: efficiency below requirements” appears on 12.8% of its failures against 2.6% for cars of the same age, and “Steering rack: gaiter missing or no longer prevents the ingress of dirt” appears on 8.3% of its failures against 2.5% 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 106 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.

- 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.
