0445110141 — Technical Research
Bosch solenoid common-rail injector for the Renault-Nissan-GM 2.5 dCi/DTI (G9U) engine in the Renault Master II, Nissan Interstar and Vauxhall/Opel Movano. Renault OE 7701474813/8200146357; Vauxhall/Opel 9109795/93190346. Closely interchanges with 0445110083. Failures are driven by poor fuel filtration, contamination and back-leakage. Key symptoms: Rough idle / vibration; Hard starting; Loss of power / limp mode; Black smoke. Common failure modes: Internal wear / high back-leakage; Water-in-fuel corrosion; Nozzle coking.

A leaking injector unbalances cylinder fuelling on the 2.5 dCi G9U.
Excess back-leakage drops cranking rail pressure.
Out-of-range delivery or rail-pressure deviation cuts power.
Poor atomisation over-fuels the cylinder.
Cylinder-specific injector or fuel-metering codes.
- InstallationFollow the diagnostic for the specific ECU; the early G9U common-rail injectors typically carry no correction code - verify before road test.
- InstallationRenew the copper combustion washer and leak-off seals; torque the clamp to spec.
- MisdiagnosisRead live back-leakage data to find the weak cylinder before removal.
- WarningFix contamination (filter/water/debris) first; high-mileage vans are sensitive to fuel quality.
- TestingBench-test across delivery and back-leakage points; verify spray pattern before refit.
What is Bosch injector 0445110141?+
A Bosch solenoid common-rail diesel injector for the Renault-Nissan-GM 2.5 dCi/DTI (G9U) engine in the Master II, Interstar and Movano. Renault OE 7701474813/8200146357.
Which vehicles use 0445110141?+
Renault Master II, Nissan Interstar/Primastar and Vauxhall/Opel Movano A 2.5 dCi/CDTi (G9U).
Is it solenoid or piezo?+
It is a Bosch solenoid common-rail injector.
Does 0445110141 need coding?+
The early G9U common-rail injectors typically carry no correction code, but verify with the diagnostic for the specific ECU when fitting.
What are the OE part numbers?+
Renault 7701474813/8200146357 and Vauxhall/Opel 9109795/93190346 reference Bosch 0445110141; 0445110083 is a close interchange.
Is 0445110141 the same as 0445110083?+
They are closely interchangeable on the G9U engine - confirm the OE number and engine code before fitting.
What are the symptoms of failure?+
Rough idle, vibration, hard starting, black smoke, power loss/limp mode and an EML.
Why does my 2.5 dCi Master run rough?+
A worn or leaking injector unbalances fuelling; read live back-leakage data and bench-test the suspect cylinder.
What causes these injectors to fail?+
Poor fuel filtration, contamination and back-leakage wear - fix the cause first.
Does a remanufactured 0445110141 perform like new?+
A properly remanufactured injector is bench-tested and recalibrated to the Bosch plan before refitting.
