Citroën C4 I problems (2004–2010)

We have documented 5 engines and 1 gearbox for the Citroën C4 I; the 1.6 HDi, the 1.6 THP, the 1.4/1.6 VTi, the 1.4 and 1.6 TU3/TU5 and the AL4 / DP0 gearbox have high or critical severity faults. The safest option is the 2.0 and 2.2 16v EW10/EW12 in the 2.0 16v 136 hp (EW10J4, RFN/RFR, 1999-2005) and 2.0 16v VVT 140-143 hp (EW10A, RFJ, 2004-2011) versions, with a «Buy» verdict.[1][2][3][4][5][6][7][8][9]

Outside the engine: Outside the engine, the Citroën C4 I (2004-2010) has no specific safety recalls documented in the databases consulted, but a reliability survey with 573 responses puts the electric windows, the front suspension, electronic faults in the BSI and the COM2000 stalk, and the clutch as the most cited non-engine weak points.[8]

    With caution

    It shares with the 110 the risk of turbo failure through lack of lubrication and leaks at the injector washers. Worth buying only with a complete oil history and, if the turbo has been replaced, with the lubrication pipe and circuit cleaning done.[11][14][15]

    With caution

    It is the version with the most complaints in the family (turbo, injection, EGR, DPF and dual-mass flywheel). It is only worth it with demonstrable maintenance and, if the turbo has already been replaced, with the complete cleaning procedure documented on the invoice.[11][15][16]

Faults that affect the C4 I

Only those that affect the versions and years that this car used. The 1.6 HDi has 7 documented faults in total.

  1. High severityFrequency: Very frequentTurboTurbo failure through lack of lubrication (carbon deposits and union filter)On the 16-valve 1.6 HDi/TDCi engines (2004-2011) the turbo can seize because carbon deposits from the oil clog the mesh filter in the union that feeds it. It is a serious, repeat fault: if only the turbo is replaced without cleaning the circuit, it fails again.Repair (garage): €700–€1,050
  2. High severityFrequency: Very frequentTimingTiming belt failure and premature wearOn the 8-valve 1.6 HDi/e-HDi 112/115 built between October 2010 and September 2011 the belt could break and leave the car stranded. PSA covered the repair and in 2014 preventively replaced the belt and crankshaft sprocket on those that had passed 120,000 km.
  3. Medium severityFrequency: CommonInjectionLeaks at the injector washers and carbon build-up in the cylinder headIt is common for the copper washers of the 1.6 HDi injectors to stop sealing: the engine blows gases, carbon forms around the injector and soot gets into the oil. It is cheap to repair, but if left it contaminates the oil and is one of the causes of turbo failure.Repair (garage): €110–€310
  4. Medium severityFrequency: CommonEmissions controlAdditive-fed particulate filter (Eolys cerine): depleted additive and cloggingThe DPF on the 1.6 HDi and BlueHDi works with an additive (cerine) that runs out at 80,000-120,000 km and has to be topped up for around €100-120 (price in Spain). With a lot of town use the filter clogs and the warning appears; if it is left, a new DPF costs around €1,500.Repair (garage): €100–€1,500Appears at around 80,000 km
  5. Medium severityFrequency: CommonEmissions controlDirty EGR valve and EGR cooler leaksThe 1.6 HDi EGR valve gets dirty easily, especially in town use, and causes jerking and stalling at idle. On the 8V engines the EGR cooler also fails, consuming coolant with no visible leaks.

    With caution

    It does not inherit the chain risk documented on the turbo versions, but it shares with the whole Prince family the fragility of the water pump and heat exchanger described by fiches-auto.fr.[18]

  • 1.6 THP medium output (EP6DT/EP6DTS/EP6CDT, N14/N18; 140-190 hp)2006–2018 · 140–190 hp · EP6DT, EP6DTS, EP6CDT, N14, N18

    With caution

    Real risk of stretching of the timing chain and tensioner on pre-2012 units, which can be checked by listening to the engine cold and reviewing the service history; it also shares the oil consumption and the high-pressure pump failures documented across the whole turbo family.[19][20][21]

Faults that affect the C4 I

  1. Critical severityFrequency: CommonTimingTiming chain and tensioner stretch (turbo versions, before 2012)Yes: on the turbo versions of the 1.6 THP, built mostly before 2012, the timing chain and its tensioner wear out prematurely; if the chain jumps teeth, the engine can go out of time or seize. BMW, co-designer of the block, issued a technical bulletin on this fault in 2013.
  2. High severityFrequency: CommonCoolingFragile water pump and heat exchangerYes: both the naturally aspirated 1.6 VTi and the turbo 1.6 THP share, according to fiches-auto.fr, a water pump and a heat exchanger described as fragile; in the most serious cases, the resulting overheating has gone as far as damaging the cylinder head.
  3. Medium severityFrequency: CommonInjectionHigh-pressure fuel pump (HPFP) failure on the turbo versionsThe high-pressure pump that feeds the direct injection of the turbo (THP) versions can fail. MINI, which uses the same block in the Cooper S, extended the warranty on this part in 2010 to 10 years or 192,000 km for 2007-2009 models in the US, without the need for a recall.
  4. Medium severityFrequency: CommonLubricationOil consumption on the turbo versionsYes: oil consumption between changes is one of the defects that the French motoring press repeatedly associates with the turbo versions of the 1.6 THP, used by Peugeot, Citroën and MINI. We have not found that PSA or BMW acknowledged a specific campaign or extended warranty for this reason.
  5. Medium severityFrequency: OccasionalIgnitionSpark plugs and ignition coils that wear out early on the 1.6 THPOn the 1.6 THP turbo a noticeable minority of owners replace spark plugs and coils earlier than expected: fiches-auto.fr records ignition warnings in 12% of opinions on the 200 hp THP. It causes judder and the engine warning light.

    With caution

    It shares with the rest of the Prince family the risk of timing chain and tensioner wear flagged by a specialist German garage, and fiches-auto.fr documents frequent oil consumption in this displacement; however, it does not inherit the problems specific to the direct injection of the turbo versions.[20][23]

  • 1.6 16v / VTi (EP6/EP6C, N12/N16; 118-121 hp)2007–2015 · 118–121 hp · EP6, EP6C, N12, N16

    With caution

    It shares with the rest of the Prince family the risk of timing chain and tensioner wear flagged by a specialist German garage, and fiches-auto.fr documents both frequent oil consumption and a fragile water pump and heat exchanger, shared with MINI and with the turbocharged 1.6 THP.[18][20][23]

Faults that affect the C4 I

  1. High severityFrequency: CommonCoolingFragile water pump (and expansion tank or heat exchanger, depending on displacement)Yes: fiches-auto.fr describes a fragile water pump in both the 1.4 VTi (with an expansion tank prone to leaks) and the 1.6 VTi (with the heat exchanger), a cooling problem that the turbocharged 1.6 THP inherits from this naturally aspirated version.
  2. Critical severityFrequency: OccasionalTimingWear of the timing chain and tensionerYes, although with fewer documented cases than on the turbocharged 1.6 THP: a German garage says the timing chain and its tensioner can wear in any version of the Prince family, including the naturally aspirated one, although the most reported cases in forums are on the turbo engine.
  3. Medium severityFrequency: CommonLubricationOil consumption on the 1.4 and 1.6 VTi versionsYes: fiches-auto.fr documents frequent oil consumption in both the 1.4 VTi (93 of 245 reports) and the 1.6 VTi (173 of 533 reports). We have not found that PSA or BMW have acknowledged a specific campaign or extended warranty for this reason.

    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][25]

Faults that affect the C4 I

  1. 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
  2. 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
  3. 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.
  4. 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
  5. 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

    With caution

    It is an old design (late 1990s) that is no longer in production; we have not found specific documentation of faults unique to the AL4, but given its age and the general pattern of any automatic gearbox with infrequent oil maintenance, you should check the service history before buying.[27][28]

Faults that affect the C4 I

  1. High severityFrequency: OccasionalTransmissionDegraded oil: harsh shifts, slipping and overheatingYes: as with any automatic gearbox, if the AL4/DP0 oil degrades or drops in level, harsh shifts, slipping and overheating appear. We have not found a specific change interval from PSA or Renault, but several sources recommend checking it even if the manufacturer does not list it as necessary.
  2. Low severityFrequency: OccasionalTransmissionJolt or sharp thud when engaging a gear from a standstillIt is a symptom described in general terms for automatic gearboxes with degraded oil: a jolt or a sharper thud than normal when moving from park or neutral into gear, especially when cold. We have not found sources confirming whether the AL4/DP0 suffers from it more than other gearboxes of its era.

    With caution

    There are few reviews (6 for the 206, 6 for the 307 and 5 for the C4) and they mention coils, catalytic converter, EGR and even an engine replaced under warranty in a C4; as this is an engine used hard, it is worth checking the service history and the condition of the ignition and exhaust.[2][3][8]

Frequently asked questions

Is the Citroën C4 I reliable?

We have documented 5 engines and 1 gearbox for the Citroën C4 I; the 1.6 HDi, the 1.6 THP, the 1.4/1.6 VTi, the 1.4 and 1.6 TU3/TU5 and the AL4 / DP0 gearbox have high or critical severity faults. The safest option is the 2.0 and 2.2 16v EW10/EW12 in the 2.0 16v 136 hp (EW10J4, RFN/RFR, 1999-2005) and 2.0 16v VVT 140-143 hp (EW10A, RFJ, 2004-2011) versions, with a «Buy» verdict. Outside the engine, the Citroën C4 I (2004-2010) has no specific safety recalls documented in the databases consulted, but a reliability survey with 573 responses puts the electric windows, the front suspension, electronic faults in the BSI and the COM2000 stalk, and the clutch as the most cited non-engine weak points.

Which Citroën C4 I engine is the most reliable?

Among the 5 engines and 1 gearbox we have documented, the safest option is the 2.0 and 2.2 16v EW10/EW12 in the 2.0 16v 136 hp (EW10J4, RFN/RFR, 1999-2005) and 2.0 16v VVT 140-143 hp (EW10A, RFJ, 2004-2011) versions, with a «Buy» verdict. It is the simplest 2.0 (no variable valve timing or direct injection) and owner reviews of the 206, 406, Xsara Picasso and 307 point to wear parts - coils, lambda sensors, catalytic converter or manifold - rather than internal failures; gebrauchtwagenberater.de describes the 307's petrol engines as simple and easy to maintain.[1][2][3][4][5][6]

What problems does the Citroën C4 I have apart from the engine?

Outside the engine, the Citroën C4 I (2004-2010) has no specific safety recalls documented in the databases consulted, but a reliability survey with 573 responses puts the electric windows, the front suspension, electronic faults in the BSI and the COM2000 stalk, and the clutch as the most cited non-engine weak points. The most important documented faults are: recall: the bonnet catch could open (bodywork and interior, high severity), recall: brake servo fault (brakes, high severity), wear of shock absorbers, ball joints and wheel bearings on the front axle (suspension, medium severity) and premature wear of the clutch and flywheel (gearbox and clutch, medium severity).[8]

What faults does the Citroën C4 I have?

The most important by severity and frequency, on the engines we have documented, are: timing chain and tensioner stretch (turbo versions, before 2012) (1.6 THP, critical severity), turbo failure through lack of lubrication (carbon deposits and union filter) (1.6 HDi, high severity), timing belt failure and premature wear (1.6 HDi, high severity), fragile water pump and heat exchanger (1.6 THP, high severity) and fragile water pump (and expansion tank or heat exchanger, depending on displacement) (1.4/1.6 VTi, high severity).

What is the best year to buy a Citroën C4 I?

According to our rating by year, the best are 2005 and 2004 (6.0/10); the worst rated is 2009 (5.1/10). Each year's rating counts only the engines sold that year and the faults that affect those units: open each year to see what changes.

Does the Citroën C4 I have recalls?

Yes: we have documented 2 campaigns for the Citroën C4 I, such as KBA recall: bonnet catch. Check with your VIN at the official service centre whether yours has been done.
