0445115022 — Technical Research
Bosch CRI3 piezo common-rail diesel injector for the Renault/Nissan 2.0 dCi M9R engine, Bosch 0445115022 (same-family alternate 0445115007), Nissan/Renault OE 16600-00Q0A, Bosch exchange 0986435390. Fitted to the Nissan X-Trail T31 and Qashqai J10, Renault Trafic II, Laguna III and Espace IV, and the Vauxhall/Opel Vivaro 2.0 CDTi. Common failure drivers on these M9R injectors are fuel contamination, piezo-stack wear and nozzle coking that raise back-leakage until the ECU can no longer compensate. Confirm the stamped Bosch number 0445115022 before ordering - the 2.0 dCi M9R injector is NOT interchangeable with the Mercedes OM642 3.0 V6 (0445115059/061/063/064), the Renault/Nissan 2.3 dCi M9T (562001910) or the 1.5 dCi K9K injectors. Key symptoms: Hard starting / extended cranking; Rough idle and vibration; Loss of power / limp mode; Black smoke. Common failure modes: Piezo-stack wear / drift; Nozzle coking / poor atomisation; High back-leakage.

Confirm the stamped Bosch number 0445115022 before ordering - the 2.0 dCi M9R injector is NOT interchangeable with the Mercedes OM642 3.0 V6 (0445115059/061/063/064), the Renault/Nissan 2.3 dCi M9T (562001910) or the 1.5 dCi K9K injectors. Key symptoms: Hard starting / extended cranking; Rough idle and vibration; Loss of power / limp mode; Black smoke. Common failure modes: Piezo-stack wear / drift; Nozzle coking / poor atomisation; High back-leakage.
High back-leakage from a worn piezo injector drops cranking rail pressure on the M9R, making the engine slow to start, especially when cold.
An out-of-balance injector unevenly fuels its cylinder, producing a shaky idle and audible misfire on the X-Trail/Trafic.
When injector delivery falls outside its correction range the ECU pulls fuel and boost or drops the vehicle into limp mode.
Poor atomisation from a worn nozzle over-fuels the cylinder, producing visible black smoke under load.
A leaking injector causes a pronounced top-end knock on the M9R, often most obvious at idle.
Internal leakage and over-fuelling waste fuel and can trigger fuelling-related fault codes.
- codingEach Bosch injector carries an individual calibration/correction code that must be written into the ECU with a Renault/Nissan-capable tool (CLIP/Consult) after fitting; without coding the M9R runs on default trim and may log cylinder-balance faults.
- InstallationReplace the fuel filter and check for water/debris before fitting - contaminated fuel is the leading cause of repeat failure on the M9R.
- InstallationFit a new injector sealing washer and use the correct tightening torque; a reused or crushed washer causes combustion blow-by around the injector bore.
- MisdiagnosisRead live injector correction and back-leakage values to find the weak cylinder before removal rather than replacing all four injectors blind.
- WarningConfirm the stamped Bosch number 0445115022 before ordering - the 2.0 dCi M9R injector is NOT interchangeable with the Mercedes OM642 3.0 V6 or the Renault/Nissan 2.3 dCi M9T injectors.
- TestingBench-test on a Bosch-capable common-rail tester (CR318-PRO or equivalent) across delivery and back-leakage points; verify spray pattern and cylinder balance before refitting.
What is Bosch injector 0445115022?+
A Bosch CRI3 piezo common-rail diesel injector for the Renault/Nissan 2.0 dCi M9R engine. Nissan/Renault OE 16600-00Q0A, Bosch exchange 0986435390.
Which vehicles use 0445115022?+
Nissan X-Trail T31 and Qashqai J10, Renault Trafic II, Laguna III and Espace IV, and the Vauxhall/Opel Vivaro 2.0 CDTi, all with the 2.0 dCi M9R engine.
Is it solenoid or piezo?+
It is a Bosch CRI3 piezo common-rail injector.
What is the Nissan/Renault OE number for 0445115022?+
16600-00Q0A. The Bosch exchange number is 0986435390. Always confirm the number stamped on your original injector before ordering.
Is 0445115007 the same as 0445115022?+
0445115007 is a same-family M9R alternate that is generally sold interchangeably with 0445115022 across model years. Match the exact number stamped on your injector.
What are the symptoms of a failing 0445115022?+
Hard starting, rough idle and vibration, loss of power or limp mode, black smoke, diesel knock and higher fuel consumption.
Why does my X-Trail 2.0 dCi knock or rattle?+
A leaking injector causes a top-end knock on the M9R that is often most obvious at idle. Bench-test to confirm the faulty cylinder before replacing.
What causes these injectors to fail?+
Fuel contamination, water in the fuel, piezo-stack wear, nozzle coking and high-mileage internal wear that raises back-leakage - fix the cause, not just the injector.
Do I need to code the injector to the ECU?+
Yes. Each Bosch injector has an individual correction code that must be written into the ECU with a Renault CLIP / Nissan Consult tool after fitting, or the engine runs on default trim and may log cylinder-balance faults.
Is 0445115022 the same as the Mercedes OM642 injector?+
No. The OM642 3.0 V6 uses different Bosch numbers (0445115059/061/063/064). 0445115022 is the Renault/Nissan 2.0 dCi M9R injector - they are not interchangeable.
Is 0445115022 the same as the 2.3 dCi M9T injector?+
No. The 2.3 dCi M9T (Master/Movano/NV400) uses a different injector (Continental 562001910). The 2.0 dCi M9R uses 0445115022 - confirm the stamped number.
Does a remanufactured 0445115022 perform like new?+
A properly remanufactured injector is bench-tested and recalibrated to the Bosch plan to meet original delivery and back-leakage specifications.
