1.5 Blue dCi with SCR and AdBlue (85, 95, 100 and 115 hp, from 2018) engine: faults and reliability

Renault 1.5 dCi (K9K) version

With caution

There is still little long-term data. Faults in the AdBlue system (pump, tank, injector) and emissions warnings with no real fault have been documented, and Caradisiac considers the earlier dCi 110 somewhat more reliable than the Blue dCi 115.[1][2][3]

Faults of the K9K 872 engine

The documented engine faults that affect this version and its years, from most to least important.

  1. 1Medium severityFrequency: OccasionalClutchPremature dual-mass flywheel failure and clutch problemsThe 105 and 110 hp 1.5 dCi engines can break the dual-mass flywheel early, sometimes before 40,000 km. It warns you with vibrations at idle and metallic noises, and forces you to replace the clutch and flywheel assembly.Repair (garage): €700–€1,300
  2. 2Medium severityFrequency: OccasionalEmissions controlNOx trap and AdBlue system on the Euro 6 1.5 dCiThe 2015 Euro 6b 1.5 dCi engines had a badly calibrated NOx trap that Renault corrected with recall campaigns. On the Blue dCi (from 2018), the AdBlue pump, tank or injector can fail, with an emissions warning and even the car locked out with a full tank.
