Expert verdict

Brakes: 1.9× the national share

Brakes make up 39.3% of everything recorded on the 2021 Citroen C3, against 20.9% nationally — 18.4 points above. Have the discs and pads measured rather than glanced at, and ask whether the handbrake holds on a slope.

Where the Citroen C3 is most common

Across all C3 model years on record (2002–2023): 274,772 Citroen C3 cars tested in a recordable postcode area, across 710,110 tests. Birmingham (B) has the most, with 8,507 cars tested there. Cars are counted by the postcode area of the MOT station, so this is where they were tested, not necessarily where their owners live.

The twenty areas with the most Citroen C3 cars in the record, sorted by car count — sort the columns for a different question. Cars tested at a station whose postcode area could not be resolved are counted in the model's total but in no area, so the shares add up to slightly under 100% even across every area, and an area's cars are a subset of the model's. Pass rate is blank below 30 tests in an area, where a percentage is noise rather than a finding. How this model's pass rate varies by postcode →

Before your test

Three checks worth doing on a 2021 C3

These are not generic tips — they are the faults recorded most often on this exact model, rewritten as things you can check yourself. All three take about ten minutes and cost nothing.

  1. Check the brakes 0.9% of tests

    “brake pads less than 1.5 mm thick”

    Look through the spokes of each wheel at the pad — less than 3mm of friction material, or a lip on the disc edge, is the usual failure. Check the handbrake holds on a slope with a few clicks, not at the top of its travel.

  2. Check the lights 0.6% of tests

    “headlamp aim too high”

    Switch everything on and walk round the car: both headlamps on dip and main, every indicator, both brake lights, reverse, fog and the two number-plate lamps. A bulb is a few pounds and a five-minute job.

  3. Check the tyre tread 0.5% of tests

    “tread depth below requirements of 1.6mm”

    Check all four tyres cold, including the inner shoulder where wear hides — 1.6mm across the central three-quarters is the legal limit, and most testers fail at 1.6mm without argument.

Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.

What it costs to get a 2021 C3 through its MOT

Across the 10 items that are recorded most often on this model, the average repair comes to £31–£80 — and 30% of those repairs are parts that cost under £30.
