Bosch solenoid common-rail injector for the BMW M57 3.0d engine. BMW OE 13537808089; Bosch 0445110131. M57 injectors exist in several revisions - always verify the BMW number on the injector body and VIN before ordering. Key symptoms: Misfire and rough running; Black smoke; Hard starting; Loss of power / poor performance. Common failure modes: Excessive back-leakage; Nozzle coking / poor atomisation; Worn nozzle needle/seat.
A weak or leaking injector under/over-fuels its cylinder.
Poor atomisation from a worn or coked nozzle.
Back-leakage lowers cranking rail pressure.
Rail-pressure or injector-correction faults trigger ECU derate.
Cylinder-specific injector or pressure DTCs.
Incorrect delivery quantity or timing.
- MisdiagnosisM57 injectors come in several revisions. Match the BMW number stamped on the injector body and the VIN before ordering - do not rely on model alone.
- InstallationRenew the copper sealing washer, clean the bore and torque the clamp to spec to prevent combustion blow-by.
- TipRead live injector correction/rate values to identify the weak cylinder before removal.
- TestingCommon causes of M57 injector failure are fuel contamination and poor filtration - inspect the fuel system when diagnosing.
What is Bosch 13537808089?+
A Bosch solenoid common-rail injector for the BMW M57 3.0d engine. The Bosch number is 0445110131 and the BMW OE is 13537808089.
Which BMWs use this injector?+
M57-engined 330d (E46/E90), 530d (E39/E60/E61), 730d (E65), X5 3.0d (E53) and X3 3.0d (E83).
Is 13537808089 the same as 0445110131?+
They are part of the same M57 injector family, but M57 has several revisions - verify the BMW number on the injector body and your VIN before ordering.
Is this injector solenoid or piezo?+
It is a solenoid common-rail injector.
What are the symptoms of a failing M57 injector?+
Misfire, black smoke, hard starting, loss of power, higher fuel consumption and injector/rail-pressure fault codes.
Why does the M57 misfire on one cylinder?+
Usually a weak or leaking injector on that cylinder; confirm with live correction values and a bench test.
What causes M57 injectors to fail?+
Common causes are fuel contamination, poor filtration, internal wear and sealing/torque issues - so address fuel quality too.
Can I test it on any diesel bench?+
Use a Bosch-capable common-rail bench so the M57 test plan and back-leakage targets are correct.
Should I change one or all six?+
Diagnose each with correction values and a bench test; on high-mileage engines a full set is often renewed.
Do M57 injectors need coding?+
BMW injector adjustment/IMA values should be entered for accurate fuelling; check the procedure for your model/ECU.
Why renew the copper washer?+
It is a one-use crush seal; reusing it risks blow-by and carbon build-up around the injector.
Does a remanufactured 13537808089 perform like new?+
A properly remanufactured unit is bench-tested and recalibrated to the Bosch plan to meet original delivery and back-leakage specs.
