2012 Citroen C3 — MOT failures & pass rate
The 2012 Citroen C3 passed 75.5% of its 100,983 recorded MOT tests. Against superminis of a similar age (22.6% fail rate), the 2012 C3 comes out 1.9pp worse. Failures cluster in lighting & signalling, suspension and body, structure & corrosion.
What the MOT record shows
Lighting & signalling dominates the failure mix at 17.2% of all tests — 7.3 points clear of suspension, so it is the first thing to check.
At component level the recurring items are stop lamp, position lamp and coil spring — stop lamp alone was recorded 6,507 times.
Condition tracks the odometer closely. Failures run at 13.4% in the 0-30k band and 30.7% in the 150k+ band, a 17.3-point spread — more than double.
Split by fuel, diesel examples fail 2.2pp more often than petrol ones (25.5% vs 23.3%) — worth weighing if you have a choice.
Advisories point at the next bill rather than this one: tyres was flagged on 28.6% of tests without failing them.
The trend is worsening — 21.7% of tests failed in 2021 against 26.4% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2012 C3
On a 2012 C3, lighting & signalling is what the MOT record says goes wrong most — it appeared in 17.2% of tests. Check these areas before you commit.
- Lighting & signalling (17.2% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (9.9% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
- Body, structure & corrosion (6.8% of tests): The one to take seriously on older cars — corrosion to structural areas can be costly and is an MOT failure. Typical repair: £200–£1,500+.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
