If a car like this fails, does it fail again?

A failure rate does not say whether a failure is a one-off or the start of something. This follows the same vehicles into their next ordinary MOT a year later — retests after a repair are excluded, because they follow a failure by definition. 2019-2024.

After this year's testFails next yearVehicles followed
It failed41.8%5,272
It passed35.5%32,012

A failed test raises next year's chance of failing again by 6.3 percentage points. The failure most likely to come back is lamps, reflectors and electrical equipment — 38.5% of those vehicles fail again next year. Some of this is the vehicle and some is the owner: a car that was let go once tends to be let go again. One caveat: a car that fails may be sold or scrapped rather than tested again, so these figures describe the vehicles that came back.

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 65,632 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.

Standardised forIndexReading
Age only137.1fails more often than expected
Age and annual mileage130.4fails more often than vehicles driven as much
Share doing under 3,000 miles a year0.9%a normal spread of use

Mileage matters here: matching on how much these are driven moves the figure by 6.7 points — this fleet works harder than the vehicles it is measured against, so the age-only view penalises 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 DS4 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.

Is a Citroen DS4 ULEZ compliant?

The share of classifiable 2024 Citroen DS4 MOT tests likely ULEZ compliant by first-registration date is 12.5%.

Based on 10,189 classifiable initial MOT tests. This describes the tested fleet, not a specific car. MOT data do not record Euro class, so likely compliance is inferred from fuel and first-registration date. For the only authoritative answer, check the registration with TfL's official ULEZ checker.

Takeaway: the spread between best and worst month is 6.2 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.

Why do areas differ?

For each external factor we correlate the area fail rate with the factor across postcode areas that have ≥800 tests of this family, then compare the bottom vs top fifth (quintile) of the factor. Correlation, not causation — factors travel together (the north is colder and often poorer; urban areas are denser and less salted). Road surface condition is joined now, for the 91 English areas the DfT publishes, and it explains nothing: the correlation with suspension failures is −0.01 and with body and structure failures 0.07. Potholes wreck wheels and tyres between tests, but by the time a car reaches the bay the road it drives on leaves no measurable trace.

In areas with the highest frost days this model fails 0.8 pp more often than in the lowest fifth (r=0.21, n=25 areas with ≥800 tests).

In areas with the highest urban share this model fails 2.2 pp less often than in the lowest fifth (r=-0.19, n=25 areas with ≥800 tests).

In areas with the highest mot centre density this model fails 2.2 pp more often than in the lowest fifth (r=0.19, n=25 areas with ≥800 tests).

Factors that only mean something combined

Some conditions are useless on their own and informative multiplied together. Frost days alone say little — Britain barely freezes. Salt tonnage alone says little — it tracks frost. Distance to the sea alone says little. Multiply the first two and divide by the third and you get an index of how hard an area attacks a car's underside, and it lines up with the corrosion defects we actually record. We built five such combinations and tested each against our own data. Three survived; two did not, and the failures are listed here on purpose — a proxy that was never checked is decoration. One survivor only survived on the second attempt: built from a crude stand-in for street parking it failed outright, and rebuilt from the census — terraced streets carrying more cars than they have driveways — it works, and carries information the salt index does not.

The deprivation result is the one worth dwelling on. The intuition that poorer areas defer repairs is strong enough that most people treat it as established. We tested it twice — once on raw failure rates (r = 0.04) and again, more fairly, on whether an advisory turns into a failure — and it did not hold any of the three times we tried it — on raw failure rates, on advisory-to-failure conversion, and again with deprivation measured properly inside each nation rather than England alone. We are closing it. What does predict local failure rates is the density of test centres, which is a statement about testing, not about cars.

Defects in «Steering» and «Suspension» appear together 3.58× more often than chance (566 co-occurrences in the same test; lift≥1.3, n≥500).

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).

Is low mileage better for a Citroen DS4?

Cars driven under 5,000 miles a year is well below the reference at 28.7%, against 41.4% for cars driven 8,000–12,000 miles a year.

Which Citroen DS4 engine is best?

diesel 1.5–1.8 is highest at 103.1; petrol 1.0–1.2 is lowest at 67.4 — the gap is 35.7 points.

Splitting this model by fuel alone hides the thing that actually differs. Within the same badge, the diesel 1.5–1.8 runs at 103.1 against this model's own age norm while the petrol 1.5–1.8 runs at 92.6 — a spread of 10.5 points between two cars that share a name.

Read this one with more care than the rest of the page. Age is held constant, but who buys which engine is not: the largest capacity in a range is often a performance or executive variant that is garaged, cherished and lightly driven, while the smallest is frequently a fleet or entry car worked hard from new. The gap below is real in the test records; how much of it is the engine and how much is the owner, this data cannot separate. Bands under 100 tests are not shown; bands under 5,000 tests are rough estimates.

The best build year here is 2015 and the weakest is 2013. Comparing build years sounds simple and is not: within a single year of testing, a car's build year and its age are the same number, so a naive comparison of years is a comparison of ages wearing a disguise. Each year below is measured against the same model at the same age in other cohorts, across six years of testing — 2 of 5 years come out distinguishable from their own model's age norm.

Two limits worth knowing before you act on this. Age, test year and build year are locked together by arithmetic, so the test-year effect is taken from the observed national failure level of each year rather than estimated — it is an adjustment, not a solution.

Citroen DS4 MOT repair costs

The MOT-failure repair budget per test runs from £98.12 to £186.43, against £54.85 for the test itself.

Tyres14.2 (nat. 8.7)Tyre (single mid-range 16" fitted)£90£12.78

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 £98 to £186, 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.

The number a fleet manager needs is not the failure rate, it is the year the car starts costing more. Between cars aged 10 and cars aged 11, both tested in 2024, the failure rate of this model is 4.83 percentage points higher — the steepest one-year step in this cross-section of different cars, and a natural planning point for replacement.

Repair spend uses the same modal prices as the section above, so it inherits the same limits: one typical repair per component group, not a full remedy. Downtime is the gap between the failed test and the passed re-test, which is the window a vehicle is legally off the road.

Citroen DS4 rust problems: where they corrode

Age-standardised corrosion susceptibility is well below the reference at <0.1×, against 1.00× for the national age-standardised rate.

Salt Belt exposure

percentile among the models published here, from its tests across 25 postcode areas

This Citroen DS4 virtually never fails on corrosion once age is held constant, and its owners live in areas that are saltier than most for the models we publish. Both point the same way and reinforce each other: it resists corrosion even though its owners live in saltier areas than most.

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.

Does a Citroen DS4 advisory become a failure?

Lamps, reflectors and electrical equipment are highest at 31.3%; Non-component advisories are lowest at 0.0% — the gap is 31.3 percentage points.

This is the question an advisory note actually raises, and it needs six years of test history to answer. We followed the same vehicles from one MOT to the next across 2019–2024 and measured how often a component that was merely advised came back as a genuine failure at the next test.

Read it as a budgeting horizon, not a prophecy: the most likely component above turns into a failure for about 31 in 100 cars, and the median gap is 12 months and roughly 7,079 miles. The rest were repaired, sold, scrapped, or simply held. Rows with fewer than 500 tracked advisories are not shown.

What will fail next on a Citroen DS4?

Lamps, reflectors and electrical equipment after a advisory at age 12-14 are highest at 33.3%; Visibility after a passed at age 3-5 is lowest at 6.2% — the gap is 27.2 percentage points.

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.

Failing is usually a same-week event, not a disaster. Of 18,745 failures followed through to their re-test, 45.35% were repaired and passed the same day and 52.48% within ten days; the median gap is 1 day. 47,606 defect items were cleared in the process.

Per mile driven, not per year. Dividing failures by the miles that actually went onto the odometers between consecutive tests gives 0.55 failures per 10,000 miles, on a median of 6,355 miles a year across 11,286 chains. This is the number to compare between models — an annual rate quietly rewards cars that barely leave the drive.

Two populations hide inside one model. 32.9% of these cars strung together three or more tests with nothing recorded at all, while 40.42% carried the same advisory three times or more — the same fault, noted, ignored, noted again. When you buy used you are buying one of those two histories, and the MOT record shows which.

Odometer anomalies: 0.868% of 11,287 chains show a reading lower than the previous test, with a median drop of 26,774 miles. We call this an anomaly and not fraud on purpose — instrument swaps, imports, unit mix-ups and keying errors all land in the same bucket. Obvious typos (drops under 100 miles or over 90% of the reading) are already excluded.

DVSA lists 19 safety recall campaigns for the Citroen DS4, covering roughly 98,447 vehicles in total. A recall is the manufacturer fixing a fault for free, so an open recall on your car costs nothing to clear.

Counter-intuitive, and measured on our own data: across the 25 families published here, more recalls go with a lower MOT Risk Index (r = −0.52). Heavily recalled models are not worse cars in the test bay — an active manufacturer removes the fault before it becomes an MOT failure.

Worth dwelling on how mundane the top of that list is: tyre pressure, tread depth, headlight aim. The Dutch APK records 1.291 defects per inspection against a much higher national failure rate than Britain's, and the reason is not that Dutch cars are worse — it is that the two regimes draw the line between "note it" and "fail it" in different places. Codes are the RDW's own; the English wording here is our translation of the Dutch original.

Britain is not the only country that inspects every car every year, and the Citroen DS4 is on the road in all of them. Each national regime writes its own rules, so the pass rates below are not comparable to each other — what does travel across a border is whether a model sits above or below its own country's average.

Citroen DS4 MOT: quick answers

Citroen DS4 MOT Risk Index stands out at 136.2, 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 DS4 first-time MOT pass rate?
55.27% of first attempts passed in 2024 (10,193 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 44.73% figure is the first-time initial failure rate, using 10,193 primary tests as the denominator (first-time, excluding retests). The age-adjusted MOT initial-failure ratio 136.2 is shown separately because raw rates compare fleet age as well as cars.

Data details & how to cite

Scope: class-4 vehicles (cars), initial tests only, outcomes pass / fail / fixed-on-the-spot at the station (PRS counts towards the failure rate — the defect was present at arrival). Index = observed initial failures ÷ failures expected for this fleet's exact age profile, ×100; margin of error is a 95% confidence interval. Covers ALL generations together — a 3-year-old and a 15-year-old are very different cars; a generation split is on the roadmap.
