Expert verdict
Visibility: 4.8× the national share
Visibility accounts for 23.8% of everything recorded on the 2023 Citroen C4 C-Series, against 5.0% nationally — 18.8 points above. Brakes are still the single largest share at 28.6%, but at 20.9% nationally that one is ordinary. Wipers, washers and a chip in the driver’s eyeline are the three quickest ways to fail a test that the car otherwise deserves to pass.
- When it fails, it costs. Only 27% of this model’s typical repairs come in under £30 in parts — the failures here tend to be the kind that need a garage rather than a bulb.
- Based on a small sample. 51 tests back this page. That is enough to publish and to index, not enough to treat the decimal places as precise — read the pattern, not the second digit.

What fails a 2023 C4 C-Series
Everything a tester recorded on this vehicle, grouped into the inspection sections that produced it. The notch on each bar is the national share, so you can see at a glance whether this car is unusual or just ordinary.
A test can record several items, so these percentages do not add up to 100%. The exact strings, with prices, are in the full DVSA record at the bottom of this page.
Before your test
Three checks worth doing on a 2023 C4 C-Series
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.
-
Check the brakes 3.9% 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.
-
Check the lights 3.9% of tests
“headlamp aim too low”
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.
-
Check the wipers and washers 2.0% of tests
“washers provides insufficient washer liquid”
Run the wipers with the screen wet: they should clear it in one sweep without smearing or juddering. Top the washer bottle up and check both jets hit the screen.
Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.
