Citroen C1 years to avoid? MOT pass rate by year
Citroen C1 years with MOT pass rates below the average for vehicles first used in the same year: 2006–2009. Above it: 2012–2018 and 2021. The other 4 years can't be told apart from average.

The MOT pass rate is one signal, not the whole story. An MOT checks safety and emissions on the day of the test. It doesn't record gearbox or engine faults, and a pass rate also reflects mileage and upkeep, so the table shows median mileage too. Whatever the year, the car in front of you matters more than its model's average.
First-time pass rate, all years together: initial tests passed with no repairs. 95% range 68.7% to 69.1%.
In 2025, 68.9% of the 161,843 initial MOT tests on Citroen C1 cars were passed with no repairs. The same-age average, for all vehicles first used in the same years, was 68.1%. That is 0.8 points above the same-age average.

Tests are initial MOT tests in 2025, not retests. Median miles is the middle odometer reading at the test: half had more, half had less. ± is the 95% margin of error in points (Wilson interval): a difference smaller than that could be chance. Years without a link have fewer than 10,000 tests, so they are listed here but don't have their own page.
When a car's mileage doesn't add upDoes mileage matter?
86.6% of Citroen C1 tests under 30,000 miles passed first time, against 48.9% at 120,000 miles or more. For all vehicles of the same age and mileage, the figures are 87.2% and 56.3%.
| Miles at the test | Tests | Passed first time | Against all vehicles, same age and mileage |
|---|---|---|---|
| Under 30,000 | 25,006 | 86.6%±0.5 | −0.6 ptsall: 87.2% |
| 30,000–59,999 | 55,474 | 76.3%±0.4 | +0.1 ptsall: 76.2% |

| 120,000 or more | 9,094 | 48.9%±1.1 | −7.4 ptsall: 56.3% |
Against all vehicles of the same age and mileage, C1 tests were below average under 30,000 miles, about average at 30,000 to 59,999 miles and below average at 60,000 miles or more.
Mileage is only one factor. How a car has been driven and looked after matters too. These figures show an association across all Citroen C1 tests in 2025, not what mileage does to a particular car.
Mileage is the odometer reading at the initial test. Each band is compared with all vehicles first used in the same year with a reading in the same band, weighted by this model's own tests in each year. Bands need at least 1,000 tests. 38 tests (under 0.1%) had no usable odometer reading and are left out. How we count
Common C1 problems at the MOT
MOT records show roadworthiness faults, not engine or gearbox problems. Each year page compares that year's failure areas with all vehicles first used in the same year.
What to check when viewing a C1
Lights and electrics
- Ask the seller to help you check every light: dipped and main beam, brake lights, indicators, fog lights and the number plate lamp.
- Look for cracked, misted or yellowed headlight lenses.
- Warning lights on the dashboard should come on with the ignition and go out once the engine starts.
Brakes
- On a clear road, brake firmly. The car should stop in a straight line without juddering or pulling to one side.
- Check the handbrake holds the car on a slope.
- Look through the wheels at the brake discs for deep grooves or a raised lip at the edge.
Suspension
- Push down hard on each corner. The car should rise once and settle, not keep bouncing.
- On the test drive, listen for knocks or clunks over speed bumps and potholes.
- The car should sit level when parked on flat ground.
Tyres
- Check the tread on every tyre. The legal minimum for cars is 1.6 mm across the central three-quarters of the tread.
- Look for cuts, bulges, and wear on only the inner or outer edge, which can point to an alignment problem.
- Check that the spare wheel or the tyre repair kit is there.
Then read the car's own MOT history. Advisories in the same area at several tests are worth asking about.

Tyres
Of Citroen C1 cars that passed their 2024 MOT with a tyre advisory and came back for their next MOT 10–14 months later, 8.8% failed on tyres, against 4.6% of similar cars with nothing noted. Based on 22,216 and 66,264 cars.
Cars not tested again in that window are not included: 9.9% of those with a tyre advisory and 9.3% of the others.
Brakes
Of Citroen C1 cars that passed their 2024 MOT with a brake advisory and came back for their next MOT 10–14 months later, 13.7% failed on brakes, against 7.5% of similar cars with nothing noted. Based on 21,135 and 67,382 cars.
Cars not tested again in that window are not included: 11.4% of those with a brake advisory and 8.8% of the others.
Suspension
Of Citroen C1 cars that passed their 2024 MOT with a suspension advisory and came back for their next MOT 10–14 months later, 11.2% failed on suspension, against 6.0% of similar cars with nothing noted. Based on 14,695 and 73,500 cars.
Cars not tested again in that window are not included: 12.3% of those with a suspension advisory and 8.8% of the others.
Similar cars are the same model, first-use year and mileage band. Areas are the DVSA's top-level groups, so the later fail may not be the fault that was advised. These figures describe what happened to these cars. They don't show what a repair would have changed.
How we worked this outAll models compared, with the dataCitroen C1 questions
Which Citroen C1 years have lower MOT pass rates?
Compared with all vehicles first used in the same year, these model years have below-average MOT pass rates: 2006–2009. Above average: 2012–2018 and 2021. The rest can't be told apart from average. A pass rate is one signal: it also reflects mileage and upkeep, and doesn't record engine or gearbox faults.
Is the Citroen C1 reliable?
MOT results show only part of the picture. In 2025, 68.9% of initial MOT tests on Citroen C1 cars were passed with no repairs, against a same-age average of 68.1%. That is 0.8 points above average. An MOT checks safety and emissions on the day of the test. It doesn't measure breakdowns, engine or gearbox faults, or repair costs.
What are the most common Citroen C1 problems at the MOT?
The most common failure areas are lights and electrics (in 44.4% of failed tests), brakes (in 31.4% of failed tests) and suspension (in 22.6% of failed tests). A failed test can count in more than one area.
What mileage is normal for a 10-year-old Citroen C1?
At their 2025 MOT tests, Citroen C1 cars first used in 2015, about 10 years old, had a median of 53,800 miles. Half had more and half had less.
