0445110080

The 0445110080 fits BMW M47N (4-cylinder, 2.0L, 110kW) and M57N (6-cylinder, 3.0L, 150-170kW) common rail engines from 2002+. Specific models: BMW 320d/520d (E46/E60, M47N 2002-2007/2010), BMW 330d/530d/730d (E46/E60/E65, M57N 2002-2010), BMW X3 (E83, M47N/M57N 2004-2010), BMW X5 3.0d (E70, M57N 2007-2013). Confirm by the OE nozzle code 0433171690 (DLLA160P1063+) stamped on the solenoid cap of the existing injector - not by engine code alone. Does NOT fit N47/N57 (different generation) or non-BMW engines.

The nozzle is 0433171690 (DLLA160P1063+, hole-type). The control valve is F00VC01304 (solenoid-actuated). BMW sister injectors 0445110131 and 0445110122 share the same DLLA160P1063+ nozzle and F00VC01304 valve but carry different IMA calibration codes - always verify by the OE code stamped on the existing injector before ordering.

Perform a cylinder cut-out test via your diagnostic tool (BMW INPA, Bosch KTS, or equivalent): disable each injector in turn at 1500 rpm and note the RPM drop (each cylinder contributes ~250 rpm on the M57N). Low or zero drop = dead injector. Also check return flow: disconnect the return line into a graduated container and crank the engine - any flow during cranking (before injection) indicates a stuck valve seat. Bosch DCI 200 or CP2000 test bench gives the most accurate assessment (injection quantity, spray pattern, back-leakage). Common fault codes: P0201-P0206 (injector circuit open per cylinder), P0300-P0304 (misfire), P2146-P2151 (injector group circuit fault).

On the BMW M47N/M57N platform, faulty injectors typically trigger: P0201-P0206 (individual cylinder #1-6 injector circuit open/short - open/short in wiring harness or failed F00VC01304 solenoid coil), P0300-P0304 (misfire detected, especially under load), P2146/P2147/P2148 (injector group COM1 circuit fault, cylinders 1-3), P2149/P2150/P2151 (injector group COM2 circuit fault, cylinders 4-6). Also check the injector harness connector on the valve cover - the M47N/M57N harness is known for chafing near the cylinder head, causing P020x codes even with a good injector. A loose connector at the injector body (common on high-mileage E46/E60) will also trigger P0201.

Hold-down bolt: 9 N·m + 90° angle turn per BMW TIS service manual - confirmed for E46 M47N/M57N. This is very low torque compared to other brands; it is correct for BMW. HP fuel line nut (rail side): 17mm flare nut wrench, 25-30 N·m. Return-pipe banjo bolt: 9-12 N·m with new sealing washers on both sides. Always use new copper washers on the HP banjo connections - reused washers cause fuel leaks. Never use an impact wrench on the injector-side HP line nut or hold-down bolt - shock loading deforms the F00VC01304 solenoid.

Yes - the M47N/M57N ECU requires cylinder-specific IMA (Injector Modification Adjustment) coding after installing new injectors. Use BMW INPA, Bosch ESI[tronic] 2.0, or ISTA/ISTA+ dealer-level diagnostic tools. The coding procedure learns each new injector's individual quantity correction factors into the DDE (Digital Diesel Electronics) ECU. Without coding, the ECU applies default quantity factors from the old injector - resulting in rough idle, black smoke, reduced power, and fault codes. After coding, clear all DTCs and road-test under load.

12 months typical for aftermarket replacement (per authorised Bosch distributor standards). OEM warranty follows vehicle terms. Warranty does NOT cover: (1) failure from contaminated fuel (water, debris) - always replace primary and secondary fuel filters before fitting new injectors; (2) cross-installation on non-M47N/non-M57N engines (N47/N57 or non-BMW engines); (3) installation damage from over-torque, impact wrench use on the solenoid, or wiring chafing; (4) return flow exceeding 50 mL/min per cylinder at cranking (stuck valve seat is a pre-existing condition). Always purchase from a reputable supplier that provides batch traceability and test documentation.

The most common mistake is confusing 0445110080 (M47N/M57N, DLLA160P1063+) with: (1) 0445110079 - same M47N/M57N family but different bore/cylinder head, NOT interchangeable without verifying cylinder displacement; (2) 0445110074 - short nozzle variant, different injector body, does NOT fit the same cylinder head recess; (3) ordering by BMW 7-digit OE codes (13537787234/7788609/7789670) without confirming the nozzle code is 0433171690 (DLLA160P1063+) - dealers quote one or the other depending on their catalog. Always verify by the OE nozzle code stamped on the existing injector solenoid cap.

All three (0445110080, 0445110131, 0445110122) share the same DLLA160P1063+ nozzle (OE stamping 0433171690) and F00VC01304 control valve. They are all compatible with BMW M47N/M57N platforms. The difference is the IMA (Injector Modification Adjustment) calibration code - each SKU carries a different cylinder-specific calibration stored in the ECU. Order by the exact OE code stamped on the existing injector to ensure you receive the correct IMA variant.
