Renault-Nissan-Daimler 0.9 TCe (H4Bt / M281 / Nissan HR09DET)Injection
Jerking due to an injection calibration that needs reprogramming on the 0.9 TCe
Some 0.9 TCe engines show slight jerking when accelerating because of an injection calibration that is corrected by reprogramming the ECU, without it being mechanical damage.[1]
Why this rating?
Low severity: A nuisance or wear. It does not immobilise the car or damage other parts.
Frequency rare: Fiches-auto.fr records 8 cases of jerking attributed to the injection calibration out of 610 analysed reviews (a little over 1%), a low proportion that the source itself places among the engine's minor issues.[1]
Symptoms
- Slight jerking or irregularities when accelerating which, according to the source, are resolved by reprogramming the injection.[1]Jerking: other faults that cause it · Garage soon
Why it happens
According to fiches-auto.fr, some examples show jerking that is fixed by reprogramming the injection, without the source detailing the exact technical cause of the calibration fault.[1]
If it is not repaired: No associated mechanical damage is described: it is resolved with a reprogramming of the ECU software at a workshop.[1]

Other 0.9 TCe faults
- High severityCommonFrequency: CommonCoolingCoolant leak at the thermostat housingThe 0.9 TCe can lose coolant through the thermostat housing (calorstat) gasket. It is the most-cited fault of this engine: if not detected in time, the low level can end up damaging the head gasket.
- Critical severityOccasionalFrequency: OccasionalTimingTiming chain or tensioner failureThe 0.9 TCe's timing chain tensioner can lose effectiveness over time. It is a minority of cases, but when the chain jumps the damage is serious: there is a documented case with a complete engine replacement at 80,000 km.
- High severityRareFrequency: RareTurboTurbocharger wear or failureThe 0.9 TCe's turbo can lose performance or fail, although the available statistics put it as an infrequent fault on this specific engine.
- Low severityRareFrequency: RareLubricationOil consumption (uncommon on this engine)Unlike other engines in the same family, the 0.9 TCe does not show a widespread pattern of excessive oil consumption: the sources document only a minority of cases.
