A pass rate is not a reliability score. The full Citroën C1 MOT record has the pass rate by age, every common failure and how the C1 compares with similar cars.

Petrol was the most common fuel among Citroën C1 cars tested in 2025. Diesel made up just 0.5% of tests.
Where the C1 fails its MOT
Where Citroën C1 cars that failed their 2025 MOT were marked down, as a share of all recorded failure items.
The specific items testers recorded most often were position lamp not working (5.5%), service brake performance excessively binding (4.9%) and tread depth below requirements of 1.6mm (4.2%). See every common C1 MOT failure.
These are DVSA failure records across every Citroën C1 that failed, not a claim that every C1 has these problems.
What should you check when buying a used C1?
The areas above, most common first, and what an MOT tester looks at in each.
1
Lamps, reflectors and electrical equipment
Walk round with every light on: headlights, brake lights, indicators, fog lights and the number plate lamp. Check no warning lights stay on after starting. 28.1% of C1 failure items.
2
Brakes
Make sure the pedal feels firm, the car stops in a straight line, the handbrake holds on a slope and no brake warning light is showing. 21.2% of C1 failure items.
3
Suspension
Listen for knocks over bumps, check the car sits level, and look for leaking shock absorbers and split rubber gaiters. 14.5% of C1 failure items.
4
Tyres
Check tread depth across the full width of every tyre (the legal minimum is 1.6mm), and look for cuts, bulges and uneven wear. 11.6% of C1 failure items.
5
Noise, emissions and leaks
Listen for a blowing exhaust, watch for smoke on start-up and look under the car for oil or fluid leaks. 8.1% of C1 failure items.

What the MOT record doesn't tell you
Knowing Citroën C1 failures cluster around lamps, reflectors and electrical equipment and brakes tells you what to inspect. It tells you nothing about whether the car is safe to buy. An MOT does not show money still owed on the car, a write-off, a theft record or a clocked odometer.

Used Citroën C1 FAQs
Is the Citroën C1 reliable?
MOT data does not measure reliability. It records whether a car met the roadworthiness standard on the day of its test. What it does show is a 68.9% first-time pass rate for the Citroën C1 across 162,794 tests in 2025, below the 72.3% average for all cars.
Do older Citroën C1 cars fail their MOT more often?
Citroën C1 cars aged 3 to 5 years passed 87.5% of MOT tests in 2025; for examples aged 11 years and over that fell to 60.4%. On an older example, the car's own MOT history tells you more than the model average.
What should I check before buying a used Citroën C1?
On the car itself, start with the areas it most often fails on: lamps, reflectors and electrical equipment, brakes and suspension. Then check the individual car's history: outstanding finance, insurance write-off records, stolen markers, mileage and previous keepers. None of these appear in the MOT record or on the V5C.
How do I check a Citroën C1's history?
Enter the registration of the specific car. A Carpeep car history check reports outstanding finance, write-off category, stolen markers, mileage history, previous keepers, MOT and tax status, import and export markers and scrapped status in one £15 report.
MOT figures are aggregated from the DVSA MOT Anonymised data set for 2025 (class 4 initial tests, retests excluded), licensed under the Open Government Licence v3.0. MOT results describe roadworthiness at test, not mechanical reliability.
