Citroen e-C4 — MOT statistics 2024

The Citroen e-C4 failed 17.3% of 1,410 first MOT attempts in 2024 ("first-time", excluding retests). Adjusted for the age of the fleet, its initial-failure ratio is 143.5 (100 = expected for its age profile). This car fails its MOT about 44% more often than expected for its age. Small sample — treat with care.

Age-adjusted peer: Dacia Sandero (index 144.4) — the two published results are 0.9 index points apart.

Citroen e-C4 common problems: what actually fails the MOT

Suspension stands out at 4.9 per 100 tests, against 0.9 per 100 tests across UK electric vehicles of the same ages.

family vs national — matched to UK electric vehicles of the same ages — top component groups, per 100 tests. Legend: This family · National avg. Combined labels: family / national average. A gap here reflects how these vehicles are driven, used and maintained as well as how they were built — an MOT defect is a test outcome, not a breakdown.

Citroen e-C4 MOT advisories: what gets flagged

Tyres are highest at 35.3 per 100 tests; Non-component advisories are lowest at 5.3 per 100 tests — the gap is 30.0 per 100 tests.

Advisories are wear the tester noted but didn't fail — what will need money soon.

Tyres, brakes and suspension: Citroen e-C4 against cars of the same age

Failing items per 100 initial tests, 2019-2024. The comparison group is every petrol or diesel car tested at the same age, so weight and drivetrain show up rather than fleet age.

Adjusted for how much these are actually driven

The headline index adjusts for the fleet's age. Wear, though, follows mileage: a three-year-old taxi and a three-year-old garage queen sit in the same age band. These two rows compare every car with vehicles of the same age, and then with vehicles of the same age and the same annual mileage, 2019-2024, on 1,475 tests. Both stand on the six-year corpus so they are measured on identical data — compare them with each other, not with the headline index above, which is measured on 2024 alone.

Mileage matters here: matching on how much these are driven moves the figure by 5.3 points — this fleet is driven less than the vehicles it is measured against, so the age-only view flatters it — but it does not change which side of normal the car sits on. One limit to keep in mind: mileage is partly a result of how often a car breaks down — one that spends weeks in the workshop covers fewer miles — so the mileage-matched figure can understate a real weakness. Tests with no usable odometer reading are left out of it.

How the Citroen e-C4 compares with cars of its own age and size

Not against the whole fleet — against cars of the same size class tested at the same age, 2019-2024.

Raw first-time failure rates within each age, so fleet age cannot flatter either side. A positive difference means this model fails more often than its own class at that age.

How does the Citroen e-C4 perform as it gets older?

The e-C4 at age 3 stands out at 17.6%, against 12.4% for all vehicles of the same age.

Does the month of a Citroen e-C4 MOT matter?

Apr is highest at 28.4%; Jul is lowest at 9.9% — the gap is 18.5 percentage points.

higher = larger sharecompare shares in percentage points

Chart scale: 8%–33%.

bars: Citroen e-C4 · dashed: all class-4 cars

Takeaway: the spread between best and worst month is 18.5 percentage points — noticeable seasonality. Seasonality partly reflects registration-date clustering, not weather.

Before reading the shape: most of it is not about cars. Britain changes its registration plates twice a year, and 18.9% of these cars were first registered in March with another17.1% in September — 36% in two months against the 17% an even spread would give. An MOT falls due three years after first registration, so the buying calendar becomes the testing calendar. That shapes how many cars are tested each month — not how often they fail: the busiest months here are not the worst ones, so read the failure line on its own and the volume behind it separately.

Citroen e-C4 average mileage by age

At age 3, the middle half of e-C4s runs from 14,474 miles to 30,008 miles, against 21,730 miles as the median.

Does high mileage mean more Citroen e-C4 MOT failures at the same age?

Within the same age group, split by odometer (2024 MOTs), so this separates wear from age: at ages 3–5, 16.7% of those with under 40,000 miles failed first time versus 24.1% of those with 40,000–70,000 miles.No clear mileage gap inside this age group, among cars still being tested.

line: median · band: middle half of the fleet (p25–p75)

A typical 3-year-old e-C4 has ~21,730 miles on the clock. Much more — ask why; much less — check for gaps in the MOT history.

Where in Britain the Citroen e-C4 fails its MOT most

Too few tests in any single postcode area to name one, so this is the wider picture across 1,477 tests, 2019-2024.

Raw pass/fail rates, not age-adjusted: fleets differ by region. England is split north of Sheffield, between Sheffield and Oxford, and south of it.

Citroen e-C4 faults that come together

Defects in «Tyres» and «Visibility» were seen together in 9 tests (28 pairs compared).

Lift = how many times more often both groups appear on the same test than if independent. A pair is listed from 5 tests with both faults; the lift is shown from 20, and called above chance only when its 95% interval excludes 1 (see rough estimates).

Citroen e-C4 MOT repair costs

The MOT-failure repair budget per test runs from £20.25 to £38.48, against £54.85 for the test itself.

bigger number = costs morepounds per test, MOT-failing faults only

Multiply how often each component fails on this model by what that repair usually costs, and you get the amount an owner should expect to budget per test for MOT-failing faults only — roughly £20 to £38, on top of the test fee itself. It is a budgeting figure, not a quote: the spread between a set of pads and a set of discs is most of the range.

Prices are modal quotes from a hand-kept catalogue of published UK garage guides — we do not scrape the booking sites, their terms forbid it, so this list is short and updated by hand with a source and date against each line. Each line prices one typical repair in that group, not a full remedy, and only groups our catalogue actually covers are counted. The contrast worth noticing is the second card: the legal maximum for the test has been £54.85 since 2010, while the repairs it uncovers have followed inflation the whole time.

For scale from a different direction: Warrantywise, which sees used-car warranty claims rather than test failures, puts the average claim at £2,052 across the ten highest-claim models it ranks and £539 for Honda, the lowest-claim make in its index (Warrantywise index 2026, 1.6 million claims, cars aged 3–15). Those sit an order of magnitude above the figures in this table, and the gap is the point: a warranty claim is a gearbox or an engine, which almost never fails an MOT, while the faults that do fail one are corrosion, lamps and tyres, which no warranty pays for. The two numbers answer different questions and neither replaces the other.

Citroen e-C4 rust problems: where they corrode

Salt-belt exposure stands out at 66th percentile, against 50th percentile as the middle of published models.

higher = larger sharecompare shares in percentage points

This Citroen e-C4 has too few tests to judge for corrosion once age is held constant, and its owners live in areas that are saltier than most for the models we publish.

Corrosion is the one failure mode that is as much about geography as about the car. We keep the two apart on purpose: a model can look rusty simply because it is popular in Scotland, and a model can look clean simply because it is bought in Surrey. Blending them into a single score would hide which of the two is doing the work.

Exposure is this model's tests weighted by an area corrosion index built from frost days, salt load and distance to the coast — the composite validated at r = 0.42 against corrosion defects we actually record. It is published as a rank, not a raw score, because every mainstream model skews towards low-corrosion areas for the simple reason that most of Britain's cars are in the south. Susceptibility is standardised to the national age profile, so an old fleet does not get labelled a rusty model.

What will fail next on a Citroen e-C4?

Suspension after a passed at age <3 stands out at 5.4%.

higher = more likelypercentage is the observed transition probability

The same chains, cut differently: given a car's age and how its last test went, which component most often causes trouble at the following one.

The pattern that repeats across every family: a failure at one test roughly doubles the chance of a failure on the same component at the next one, and an advisory sits about half-way between a clean pass and a failure. Age bands in years; probabilities are per car, not per defect item.

Citroen e-C4 MOT: quick answers

Citroen e-C4 MOT Risk Index stands out at 143.5, against 100 for a car with the same age profile.

below 100 is betterabove 100 is worse100 = normal for this model at that age

What is the Citroen e-C4 first-time MOT pass rate?

82.7% of first attempts passed in 2024 (1,410 tests). This is the first-time figure: retests after repair are excluded. Basis: first-time, excluding retests.

Why does this number differ from other sites?

Other sites often report a pass rate that includes retests or counts all attempts. Our 17.3% figure is the first-time initial failure rate, using 1,410 primary tests as the denominator (first-time, excluding retests). The age-adjusted MOT initial-failure ratio 143.5 is shown separately because raw rates compare fleet age as well as cars.
