Citroën C3 Pluriel
PSA entry-level diesel with common-rail injection. Economical and reliable, but low on power. Timing chain is maintenance-free.
Diesel convertible — an acquired taste
68 hp diesel in the open-top Pluriel — clattering along with the roof open has a special charm of its own. Whoever buys a diesel convertible has different priorities than driving fun.
Engine Weaknesses 6
Injectors seize in their bores through heat and carbon deposits. Removal requires specialist tools; in severe cases of seizure a replacement cylinder head is often needed.
Symptoms: Smoking exhaust, power drop, diesel smell in engine bay, misfires
Soot particles and oil coke deposits clog the turbocharger oil strainer filter. Insufficient lubrication causes bearing failure. Excessively long oil change intervals (over 15,000 km) significantly aggravate the problem.
Symptoms: Whistling or rattling turbo noise, blue smoke, lack of power, oil loss
The EGR valve becomes heavily coated with soot from exhaust gas recirculation in urban driving. A blocked valve worsens engine running, increases fuel consumption and can damage the turbocharger through oil contamination.
Symptoms: Hesitation in part-load range, increased consumption, engine warning light, poor driveability
The DV4's additive FAP filter only regenerates from around 500 °C. These temperatures are not reached in urban driving; the filter clogs prematurely. The Eolia additive in the tank extends regeneration intervals but is no substitute for motorway driving.
Symptoms: Particulate filter warning, power drop, rising oil level from fuel entry during regeneration attempts
The electric actuator on the variable geometry turbocharger sticks due to soot deposits from the exhaust. Typical on short-trip use where sufficient burn-off does not occur. Engine enters limp mode.
Symptoms: Sudden power loss, engine warning light, vehicle in limp mode with severely restricted performance. Occasional whistling from the turbo.
Glow plugs on the 1.4 HDi corrode and break off during removal. Failure rate increases from around 150,000 km. Cold-start problems caused by defective or broken glow plugs are difficult to remedy.
Symptoms: Poor cold-start behaviour, engine hard to start at temperatures below 5°C, fault code P1351 (glow plug relay circuit).
Vehicle Weaknesses 5
The C3 Pluriel roof is known for leaks at the fixing points of the roof frame at the A-pillar. Water gets into the boot and interior. Rattling at higher speeds is also typical.
As with the regular C3 I, front axle springs on the Pluriel snap due to inadequate corrosion protection. Ball joints and steering joints also wear early and cause MOT failures.
The electric roof mechanism on the Pluriel fails frequently or only opens the roof partway (approx. 20–30 cm). The hood motor or ECU and roof sensors are prone to failure.
Doors and bonnet rust from inside at the flanges, as does the tailgate. Water entering through the soft-top promotes rust in the boot and floor pan.
The C3 Pluriel headlights are not permanently sealed and allow moisture ingress. This causes condensation inside the headlamp housing and accelerates bulb failure.
