How we count this. Data: UK MOT open data, 2025. Only Class 4 cars on their first MOT of the year are counted. A car that fails and is fixed at the test station still counts as a fail in the first-attempt rate. These are raw results, not adjusted for age, mileage, or peer mix. The MOT does not test engine or gearbox internals.

Note:

These are patterns across 2009 Citroen C2 vehicles in 2025, not a prediction that any one car will have them. Faults are grouped by part of the car. A wear pattern follows age and use more than the way the car was built. They come from MOT defect codes, not manufacturer bulletins, recalls or a diagnosis of any one car.

Seat belts and restraints

One fault: seat belt mounting area, 7.4 times as often as on similar cars.

Figures below are measured across the 845 failed first attempts in 2025 that had a mileage recorded, which allows a like-for-like comparison.

We only list faults with at least 20 failures and a rate of about 2.0 times that of similar cars, which keeps one-off results out of the list.

Seat belt mounting area

Failed on 20 first tests7.4 times as often as similar carsPossible evidence

What it means

A seat belt anchorage likely to become detached in the event of a collision is graded Dangerous. The load bearing structure near an anchorage, called a prescribed area, is Major when its strength or continuity is significantly reduced or it is inadequately repaired. Anchorage points are inspected for all seat belts fitted, except a belt with no corresponding seat.

Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.

Lamps and electrical

Three faults. The strongest is the individual direction indicators (front): 4.2 times as often as on similar cars.

Individual direction indicators (front)

Failed on 32 first tests4.2 times as often as similar carsLikely evidence

What it means

Direction indicators must be amber, though vehicles first used before a set date may have white at the front and red at the rear when the indicators are combined with stop or position lamps, and sequential or dynamic ones are not a reason to fail. A lamp that is missing, inoperative or has more than half of a multiple light source not functioning is graded Major. A flashing rate outside the permitted range is graded Minor.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 23 first tests, 3.6 times as often as on similar cars.

Individual direction indicators (rear)

Failed on 49 first tests2.8 times as often as similar carsPossible evidence

What it means

Direction indicators must be amber, though vehicles first used before a set date may have white at the front and red at the rear when the indicators are combined with stop or position lamps, and sequential or dynamic ones are not a reason to fail. A lamp that is missing, inoperative or has more than half of a multiple light source not functioning is graded Major. A flashing rate outside the permitted range is graded Minor.

Brake light (rear)

Failed on 88 first tests2.1 times as often as similar carsPossible evidence

What it means

All stop lamps missing or not working is graded Dangerous, and so is a stop lamp that stays on when the brakes are released. A stop lamp that is missing or not working is Major. On some vehicles with LED rear lamps, part of the stop lamp can go out when the rear fog lamp is lit, which is not regarded as a defect.

Data: UK MOT open data, 2025. Compared with cars of the same age and mileage. Advisories count notes recorded on failed first tests only.

Body and structure

Two faults. The strongest is the drive shaft joints and boots (front): 3.1 times as often as on similar cars.

Drive shaft joints and boots (front)

Failed on 120 first tests3.1 times as often as similar carsLikely evidence

What it means

A constant velocity boot that is only severely deteriorated is Minor. It is Major once it is missing, split or insecure so that it no longer prevents the ingress of dirt. A transmission joint excessively worn is Major, and graded Dangerous when it is so worn it is likely to fail.

Exhaust system (rear)

Failed on 32 first tests2.0 times as often as similar carsPossible evidence

What it means

Exhaust fumes causing a danger to health of persons on board are graded Dangerous, and so is a silencer likely to become detached. Fumes entering the cabin are Major. One or more missing or defective mountings does not necessarily make the exhaust insecure, since testers assess the overall security of the system.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 46 first tests, 2.0 times as often as on similar cars.

Data: UK MOT open data, 2025. Compared with cars of the same age and mileage. Advisories count notes recorded on failed first tests only.

Brakes

One wear pattern: brake discs (front), 2.4 times as often as on similar cars.

Brake discs (front)

Failed on 34 first tests2.4 times as often as similar carsWear pattern

What it means

A brake disc or drum must be significantly worn before it is rejected, and being worn below the manufacturer's recommended limits is not a reason in itself. Significantly and obviously worn is Major, as is contamination with oil or grease. A disc or drum that is fractured, insecure, seriously weakened or missing is graded Dangerous.

Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.

Suspension

Three faults. The strongest is the wheel bearings (front): 2.2 times as often as on similar cars.

Wheel bearings (front)

Failed on 20 first tests2.2 times as often as similar carsPossible evidence

What it means

Excessive play in a wheel bearing, or a bearing that is excessively rough, is Major. Play so excessive that the bearing is likely to break up or directional control is impaired is Dangerous, and so is a bearing so rough that it is likely to overheat or break up.

Anti-roll bar linkage ball joints (front)

Failed on 55 first tests2.1 times as often as similar carsPossible evidence

What it means

Excessive wear on an anti-roll bar linkage ball joint is Major. A joint likely to become detached is graded Dangerous.

Suspension mounting area (rear)

Failed on 43 first tests2.0 times as often as similar carsPossible evidence

What it means

The load bearing structure within a set distance of a sub-frame, spring or suspension component mounting is a prescribed area. Major applies when its strength or continuity is significantly reduced or it is inadequately repaired. Dangerous applies when it is so weakened that control of the vehicle is likely to be adversely affected.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 33 first tests, 2.2 times as often as on similar cars.

Data: UK MOT open data, 2025. Compared with cars of the same age and mileage. Advisories count notes recorded on failed first tests only.

Advisories

Other things testers noted as worn or close to failing, more often than on similar cars.

An advisory is a note from the tester about something that has not failed yet. It is an early warning, not a fail. Advisories for the faults above are shown with those faults.

FAQs

Short answers about how to read this model-year guide.

The 2009 Citroen C2 follows the pattern of the model years either side. Its main cause of failure was Drive shaft joints and boots (front), about 14 in every 100 failed tests. In 2025, 49.1% of 1,659 first MOTs on the 2009 Citroen C2 passed first time (PRS: items fixed at the station the same day, counted as a fail). The official-style rate including PRS is 57.9%. Among 845 failed first-attempt MOT tests (test year 2025), Seat belt mounting area appears more often than on similar cars (2.4% of those tests; 20 observed failures; about 7.4× more often than similar cars). There is no single reliability score here; this is a pre-purchase checklist built from DVSA open data, not a guarantee for any individual car.
Ranked by how often they were actually recorded, the items that most often failed a 2009 Citroen C2 at the first attempt were Drive shaft joints and boots (front) (14.2%), Individual sidelight or tail light (front) (13.1%) and Brake light (rear) (10.4%), each as a share of the year's failed first attempts. That is what goes wrong most often on the car. The common faults table shows a different measure: faults that are unusual compared with similar cars.
Among failed first-attempt tests we highlight patterns that appear more often than on similar cars. Top example: Seat belt mounting area (2.4% of those tests; 20 observed failures; about 7.4× more often than similar cars). These are statistical signals, not a diagnosis of any individual car.
Seat belt mounting area shows up more often than on similar cars (2.4% of those tests; 20 observed failures; about 7.4× more often than similar cars). That does not prove a design fault. Age, mileage, and how the car was used still matter. Treat it as a pre-purchase checkpoint, not a manufacturer service bulletin.
Common MOT problem areas for the 2009 Citroen C2 include Seat belt mounting area, Individual direction indicators (front), Drive shaft joints and boots (front). These are the faults that stand out compared with similar cars, not a complete list of what can go wrong on any individual car.
Advisories flag issues noted at the test and are not a fail rate. We show advisory patterns that appear more often than on similar cars among failed first-attempt tests, separate from common failure rows. Use them as early-warning checks, not as a pass/fail score.
This page highlights MOT failure patterns for the 2009 Citroen C2 (registration year) using UK DVSA open data for the selected test year. Patterns are compared with cars of a similar age and mileage.

No. MOT tests do not cover engine internals, gearboxes, or many electronic modules. Patterns here come from MOT defect statistics only and should not be read as engine or gearbox reliability scores.

About this data

How this page is built and what it can (and can't) say.

These figures come from UK MOT open data for this model year. We surface common failure patterns against similar cars, not a full reliability score, and not a pass/fail verdict on any individual vehicle.

2024 2025

What we include

UK Class 4 cars only. Normal MOT tests (not retests); first test per vehicle per calendar year; results pass, PRS, or fail.

Same-day repairs

PRS means the car failed items that were fixed at the test station and then passed the same day. We count PRS as a first-attempt fail in headline rates so same-day repairs do not hide problems.

How we compare

We compare this model year with other Class 4 cars of similar age and mileage in the same test year. This model family is left out of the peer group so the car is not measured against itself.

What this does not cover

  • MOTs do not cover engine internals, gearboxes, or many electronics; this is not a full reliability score.
  • Common faults come from MOT defect stats, not manufacturer TSBs or recalls.
  • Age and mileage matching reduces, but does not remove, differences in how cars were used and maintained.
  • If the data for a car is too thin to say anything useful, we say so rather than guess.
