What changes compared with the 2003 Citroën C2
- Score: 7.1 → 6.9
- New engines or gearboxes: 1.4 HDi
- Starts to be affected by: injectors that lose their seal and let diesel escape (1.4 HDi), timing belt and water pump (1.4 HDi), premature turbo wear from poor lubrication (1.4 HDi) and eGR valve clogged with carbon (1.4 HDi) and 1 more
1.4 HDi engine in the 2004 Citroën C2
Names: 1.4 HDi 68
- With caution
1.4 HDi/TDCi 54/68/70 8V (DV4TD, 2001-2009)
54–70 hp · DV4TD, 8HT, 8HX, 8HZ
It shares the injector fragility of the rest of the family, documented in both the 68 and 70 hp versions, along with occasional turbo and EGR valve failures. It is worth buying with a maintenance history and no noticeable diesel leaks.[3][4]
Faults that affect 2004 cars
- Medium severityFrequency: Very frequentInjectionInjectors that lose their seal and let diesel escapeThe most cited weak point of the 1.4 HDi is its injectors: over time they can lose their seal and let diesel escape, which is usually noticed as a smell of diesel in the car. It appears in the two most common outputs (68 and 70 hp) and in both cases it is identified as the engine's main weakness.
- High severityFrequency: OccasionalTimingTiming belt and water pumpThe 1.4 HDi uses a timing belt (with an additional short chain on the 16-valve version), and Fiches-Auto documents some of its failures, along with the water pump, at around 100,000 km. We have not found the manufacturer's official change interval in a reliable source.
- Medium severityFrequency: OccasionalTurboPremature turbo wear from poor lubricationThe BorgWarner KP35 turbo of the 8-valve version can wear out early when the oil degrades and forms carbon deposits, reducing its lubrication. It is a minority but recurring fault: it appears in just over 9% of the reports collected for the 68 hp version.
- Medium severityFrequency: OccasionalEmissions controlEGR valve clogged with carbonThe EGR valve, which recirculates part of the exhaust gases to reduce emissions, can seize or clog up with the carbon those gases carry. It appears in a noticeable minority of the reports collected for the 68 hp version.
- Medium severityFrequency: RareTimingCrankshaft damper pulley wearThe crankshaft pulley incorporates a rubber ring that dampens engine vibrations and that can lose grip or crack over time. We have found only one specific report of this fault (a Peugeot 206 at around 250,000 km), so we do not consider it a widespread fault.
1.4 and 1.6 TU3/TU5 engine in the 2004 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.[6][7]
- 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.[6][7][8]
Faults that affect 2004 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 2004 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.
