Common faults

These are MOT failure patterns that show up more often on this registration year than on similar cars of the same class, age band, and mileage in the same test year (leave-one-out peer comparison; whole model family excluded).

Statistical patterns from MOT defect codes — not manufacturer TSBs, recalls, or a diagnosis of any individual car. Fail and advisory patterns are kept separate.

Advisories

Advisory items recorded on failed first-attempt tests that appear elevated versus peers. Advisories are not a fail rate — they flag issues noted at the test, often before they become failures.

FAQs

Is the 2012 Citroen C1 reliable?

We do not show a single reliability score for the 2012 Citroen C1 on this page. Among 4,585 failed first-attempt MOT tests (test year 2025), Linkage pins and bushes (front) appears more often than on similar peer cars (about 23.0× more often than peers; 183 observed failures; 4.0% of failed tests). Treat this as a pre-purchase checklist from DVSA open data — not a guarantee for any individual car.

What common MOT faults stand out on the Citroen C1 2012?

Among failed first-attempt tests we surface patterns that appear more often than on similar peer cars. Top example: Linkage pins and bushes (front) (about 23.0× more often than peers; 183 observed failures; 4.0% of failed tests). These are statistical signals, not a diagnosis of any individual car.

Why does Linkage pins and bushes (front) stand out?

Linkage pins and bushes (front) shows up more often than on similar peer cars (about 23.0× more often than peers; 183 observed failures; 4.0% of failed tests). That does not prove a causal design fault — age, mileage, and usage still matter. Treat it as a pre-purchase check point, not a manufacturer TSB.

What are common problems with the 2012 Citroen C1?

Common MOT problem areas for the 2012 Citroen C1 include Linkage pins and bushes (front), Hazard warning — Switch, Component mounting prescribed areas (rear). These are elevated versus similar peer cars where lift clears our floors — not a full list of every possible fault on an individual car.

How should I read advisories vs fails?

Advisories flag issues noted at the test and are not a fail rate. We show advisory patterns that look elevated versus peers among failed first-attempt tests, separate from common failure rows. Use them as early-warning checks, not as a pass/fail score.

What does this Citroen C1 2012 MOT report cover?

This page highlights elevated MOT failure patterns for the 2012 Citroen C1 (registration year) using UK DVSA open data for the selected test year. Patterns are ranked against similar age and mileage peers. It is a buyer checklist from MOT defect statistics — not a full service history or manufacturer TSB list.

Does this include engine and gearbox problems?

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.

What is PRS, and why does it count as a fail?

PRS means the vehicle 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.

About this data

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

PRS policy. PRS means the vehicle 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.

Peer baseline. We compare this model year with other class 4 cars of similar age and mileage in the same test year, excluding the whole model family so the car is not compared with itself (leave-one-out peer baseline).

Data years. Test years covered: 2024, 2025.

Limitations.

MOT tests do not cover engine internals, gearboxes, or many electronic modules — so this is not a full reliability score.
Common faults are inferred from MOT defect statistics, not manufacturer TSBs or recalls.
Matching on age and mileage reduces but does not remove every usage or maintenance difference between cars.
Pass rates and star scores appear only when those data marts are available; this page never invents them.
