Other Faults on This Variant
Injector Return Pipe Failure
SevereThe K9K 1.5 dCi in the Clio Mk3 has a known failure on the injector fuel return pipes. The plastic fittings crack and cause a fuel leak — a fire risk that must be addressed immediately.
EDC Automated Clutch Actuator Failure
SevereThe EDC (Easy Drive) semi-automatic gearbox variant of the 1.5 dCi Clio uses an electric clutch actuator. When this fails, the car refuses to move — and replacements are expensive.
Delphi Fuel Injector Failure
CriticalEarly 1.5 dCi engines (K9K) used Delphi fuel injectors that were highly prone to failure, causing misfires and sometimes producing metal swarf that destroys the entire fuel system.
