Renault 0.9 TCe (H4Bt) engine: reliability and faults

Petrol · 898 cm³ · 90, 95, 110 hp · 2012–2020

Good choice, check first
Reliability
4.0/5

3 known faults

Verdict

A turbo three-cylinder of 898 cm³ introduced in 2012 on the Clio IV, then fitted to the Captur I and the Twingo III (90, 95 and 110 hp). Fiches-auto considers it rather good overall, but its weak point is a coolant leak at the thermostat, caused by a fragile seal, which can damage the head gasket if it goes unnoticed. The lambda probes do not last long and the turbo is considered fragile on the Twingo. Monitor the coolant level and ask for invoices.

Known faults

Thermostat / water housing leak

Severity 2/3 · Costly

Fiches-auto cites a frequent coolant leak at the thermostat (calorstat), caused by a fragile seal: harmless if spotted early, it can require a head gasket replacement if it goes unnoticed. Of 14 Clio IV 0.9 TCe inspected by a partner garage of Car Verif, seven showed a thermostat seal leak.

Lambda probes that do not last

Severity 1/3 · Annoying

Fiches-auto indicates that the lambda probes of the 0.9 TCe are not very durable; their failure triggers the engine warning light.
