Faults that affect 2018 cars
- High severityFrequency: OccasionalEmissions controlClogged or broken EGR valve damaging the turboThe 2.3 dCi's EGR valve clogs with soot in urban use and, if it breaks, its fragments can damage the turbo. A French source cites bills of €1,200 to €2,300 for the EGR and turbo together.Repair (garage): €1,200–€2,300
- Medium severityFrequency: OccasionalInjectionFaulty injectors on the 2.3 dCiSome 2.3 dCi engines show the "injection problem" warning and go into limp mode, sometimes at low mileage. One source indicates between €400 and €1,800 for the repair.Repair (garage): €400–€1,800
- Medium severityFrequency: OccasionalEmissions controlDiesel particulate filter (DPF) clogged in urban useIn urban deliveries with little mileage the particulate filter may fail to regenerate and become clogged. One source puts the servicing or replacement at between €350 and €1,500.Repair (garage): €350–€1,500
- High severityFrequency: RareFuelFuel pipe rubbing against the wiring harness (recall 0EC1)In July 2024 Renault recalled 35,039 Master 2.3 dCi vans built from 23-09-2014 to 27-09-2023 because of possible rubbing of the fuel pipe, which could leak. The fix is a spacer.
- Low severityFrequency: RareEmissions controlSCR system and AdBlue tank faultsOn Euro 6 engines with AdBlue there are documented SCR system faults. On the Navara D23 2.3 dCi EU6b (2016-2019) a software update campaign was carried out, covering 1,012 units in Poland.
Faults outside the engine in the 2018 Renault Master
- Critical severityFrequency: OccasionalAirbags and safetyLoose or missing passenger airbag mounting bolts (2018-2019)A campaign notified in the EU in February 2020 affects Masters built between 17 September 2018 and 17 October 2019: the passenger airbag mounting bolts may be under-tightened or missing, and that could reduce its protection in a crash.
- High severityFrequency: OccasionalSuspensionRear right leaf spring mounts without the correct tightening torque (2018)A campaign notified in the EU in October 2019 affects Master IIIs built at Batilly between 30 March and 11 July 2018: the rear right leaf spring mounts were not tightened to the specified torque, may work loose and alter the alignment of the rear axle.
