1.4 and 1.6 TU3/TU5 engine in the 2003 Citroën C2
Names: 1.4i · 1.6 16v
- Buy
TU3 1.4 75 hp 8v (TU3JP/TU3KFX, 1994-2014)
75 hp · TU3JP, TU3KFX
It is the simplest version, with the least electronics in the whole family: with no turbo or direct injection, its most cited faults according to owners (coil, sensors) are cheap to repair and do not compromise the engine if dealt with in time.[2][3]
- Buy
TU5 1.6 16v 109-112 hp (TU5JP4/TU5NFU, from 2000)
109–112 hp · TU5JP4, TU5NFU
It is the most powerful version in the family and the one that appears most in head gasket and coil faults in the report compilations consulted, but these are still cheap repairs compared with a turbo or diesel engine of the same era.[2][3][4]
Faults that affect 2003 cars
- High severityFrequency: OccasionalCylinder head and blockHead gasket damaged after overheatingThe head gasket fails mainly as a consequence of previous overheating -from a coolant leak or a faulty thermostat- and not as a factory defect: it appears in a minority of engines, almost always between 30,000 and 180,000 km, with coolant loss, emulsified oil or white smoke.Appears at around 30,000 km
- Medium severityFrequency: CommonIgnitionIgnition coils that fail and cause jerkingThe ignition module -a rail with two twin coils, no distributor- is the electrical fault owners cite most across all models with this engine: it usually fails between 40,000 and 150,000 km and causes jerking, an unstable idle or the engine warning light coming on.Appears at around 40,000 km
- Medium severityFrequency: OccasionalCoolingThermostat stuck open or closedThe thermostat -the controlled "calorstat" on the more recent versions- can stick: if it closes, the engine overheats; if it stays open, it is slow to reach temperature and uses more fuel. It is one of the cooling faults owners of these engines cite most.
- Low severityFrequency: CommonElectronicsSensors that fail: lambda sensor and temperature sensorThe lambda sensor and the coolant temperature sensor are, along with the coils, the components most cited as faulty: they cause an unstable idle, the engine warning light coming on or a cooling fan that does not behave normally.Appears at around 25,000 km
- Low severityFrequency: CommonLubricationOil leak from the rocker cover gasketThe rocker cover gasket dries out with the years and lets oil seep into the spark plug wells: besides the oil stain on the engine, it can soak the spark plugs or the ignition module and cause misfires.Appears at around 120,000 km
Faults outside the engine in the 2003 Citroën C2
- Medium severityFrequency: OccasionalGearbox and clutchSensodrive automated gearbox faults on the Citroën C2C2 owners with the Sensodrive automated gearbox describe jerking, hesitation when engaging a gear and refusal to select a gear, according to the reports on fiches-auto.fr. There is no known public recall.
- Low severityFrequency: OccasionalGearbox and clutchPremature clutch wear on the Citroën C2According to the owner reports collected by fiches-auto.fr, the C2 clutch appears in around 24 mentions out of 235 reports, with premature wear between 45,000 and 100,000 km. No public recall or bulletin is on record.
- Low severityFrequency: OccasionalSuspensionWear of the top mounts and shock absorbers in the Citroën C2 suspensionThe fiches-auto.fr profile records around 22 mentions of C2 suspension and running gear: noises from worn top mounts and bearings between 90,000 and 150,000 km, shock absorbers failing earlier in some cases and springs breaking at high mileage.
- Low severityFrequency: OccasionalElectrical systemWindow motor and BSI module faults on the Citroën C2On the C2, the reports on fiches-auto.fr cite around 28 electrical mentions: window motors, door wiring and BSI module faults, plus false airbag warnings. No public recall is on record.
