13538514148 — Technical Research
Bosch solenoid common-rail injector (Bosch 0445110743) for the BMW B47D20 2.0-litre four-cylinder diesel, BMW OE 13538514148. Fitted across the Euro-6 1/2/3/4/5 Series and X1-X4 (F/G chassis) from 2014. Supersedes the earlier 0445110712/0445110570. Replacement injectors are calibrated to the DDE by their printed index/calibration code 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: Internal wear / high back-leakage; Water-in-fuel corrosion; Nozzle coking.

A leaking injector unbalances cylinder fuelling on the B47 2.0d.
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 index/calibration code to the correct cylinder with BMW ISTA before road test.
- InstallationRenew the combustion seal and PTFE/decoupling hardware; torque to spec.
- MisdiagnosisRead live back-leakage/smooth-running data to find the weak cylinder before removal.
- WarningFix contamination (filter/water/debris) first; the B47 is sensitive to fuel quality.
- TestingBench-test across delivery and back-leakage points; verify spray pattern before refit.
What is injector 13538514148?+
A Bosch solenoid common-rail diesel injector (Bosch 0445110743) for the BMW B47D20 2.0d engine. BMW OE 13538514148.
Which vehicles use 13538514148?+
Euro-6 BMW 1/2/3/4/5 Series and X1-X4 with the B47D20 2.0d engine, from 2014 onward.
What is the Bosch number?+
Bosch 0445110743, which supersedes the earlier 0445110712 / 0445110570 in the same application.
Is it solenoid or piezo?+
It is a Bosch solenoid common-rail injector.
Does 13538514148 need coding?+
Yes - write the injector index/calibration code to the correct cylinder with BMW ISTA when fitting.
What is the OE part number?+
BMW 13538514148 (alternate 13538514149) references Bosch 0445110743.
Does it fit the older N47 2.0d?+
No - this is the B47 modular engine injector. The earlier N47 uses a different injector; match the OE number stamped on your injector.
What are the symptoms of failure?+
Rough idle, vibration, hard starting, black smoke, power loss/limp mode and an EML.
What causes these injectors to fail?+
Poor fuel filtration, contamination and back-leakage wear - fix the cause first.
Does a remanufactured 13538514148 perform like new?+
A properly remanufactured injector is bench-tested and recalibrated to the Bosch plan, then coded on fitment.
