13537823462 — Technical Research
Bosch CRI3 piezo common-rail injector (Bosch 0445117030) for the BMW N57 3.0-litre six-cylinder diesel, BMW OE 13537823462 (interchangeable 13537823461). Used on the higher-output N57D30B variants (535d/640d/740d/X5/X6). This is the PIEZO N57 injector and is distinct from the earlier solenoid N47/N57 injector (Bosch 0445110xxx) - always confirm the injector body number. Each injector carries a calibration (volume + voltage) code written per cylinder via BMW ISTA. Failures are driven by poor fuel filtration, contamination and back-leakage wear. Key symptoms: Rough idle / vibration; Hard starting; Loss of power / limp mode; Black smoke. Common failure modes: Piezo stack / internal wear; Water-in-fuel corrosion; Nozzle coking.

A leaking injector unbalances cylinder fuelling on the N57 3.0d.
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.
- InstallationWrite the injector calibration (volume + voltage) code to the correct cylinder with BMW ISTA before road test.
- InstallationRenew the combustion seal and decoupling/clamp hardware; torque to spec.
- MisdiagnosisRead live back-leakage/smooth-running data to find the weak cylinder before removal.
- WarningConfirm piezo vs solenoid by the injector body number - do not mix the N57 piezo (0445117030) with the solenoid 0445110xxx.
- TestingBench-test on a piezo-capable CR tester across delivery and back-leakage points before refit.
What is injector 13537823462?+
A Bosch CRI3 piezo common-rail diesel injector (Bosch 0445117030) for the BMW N57 3.0d engine. BMW OE 13537823462.
Which vehicles use 13537823462?+
BMW 535d, 640d, 740d, X5 xDrive40d and X6 xDrive40d with the N57D30B 3.0d engine.
What is the Bosch number?+
Bosch 0445117030 (alternate 0986435425); BMW interchangeable 13537823461.
Is it solenoid or piezo?+
It is a Bosch piezo (CRI3) common-rail injector - distinct from the earlier solenoid N47/N57 injector.
Does 13537823462 need coding?+
Yes - write the injector calibration (volume + voltage) code to the correct cylinder with BMW ISTA.
How do I tell it apart from the solenoid N57 injector?+
Check the body number: the piezo is Bosch 0445117030 (BMW 13537823462); the solenoid is a Bosch 0445110xxx. They are not interchangeable.
What are the symptoms of failure?+
Rough idle, vibration, hard starting, black smoke, power loss/limp mode and an EML.
Why does my N57 run rough?+
A worn or leaking injector unbalances fuelling; read live back-leakage data and bench-test the weak cylinder.
What causes these injectors to fail?+
Poor fuel filtration, contamination and back-leakage wear - fix the cause first.
Does a remanufactured 13537823462 perform like new?+
A properly remanufactured injector is bench-tested and recalibrated to the Bosch plan, then coded on fitment.
