BOSCH 0445110386 Common Rail Injector for FAW CA4DC / BAW Commercial
1112010-55DF00VC01358DLLA155P21751600 bar peak rail pressureProduct Overview
The BOSCH 0445110386 is a complete high-pressure solenoid common rail injector assembly engineered for FAW (China FAW Group) commercial vehicle diesel platforms, primarily fitted to FAW light commercial trucks and pickup trucks equipped with the CA4DC engine family. The F00VC01358 solenoid control valve meters fuel flow via pulsed ground signals from the ECU, supporting a 1600 bar peak rail pressure with stable pilot and main injection sequencing for Euro 4 emissions compliance. The DLLA155P2175 multi-hole nozzle atomizes fuel via 5 x 0.155 mm orifices at 155° spray angle (internal Bosch code 0433172175). Always verify by the Bosch P/N stamping on the failed injector body before ordering.
Limited public vehicle fitment data - FAW uses internal part numbers not widely published. 0445110386 shares the F00VC01358 control-valve group with sister SKUs 0445110291, 0445110359, 0445110358, 0445110366, 0445110367, 0445110396, 0445110434 but each carries a unique IMA calibration code - NOT interchangeable without ECU re-coding.

Installation Tips
- CRITICAL banjo bolt procedure: Rail-side banjo bolt - torque to 22-25 N·m using a dedicated 14 mm or 17 mm flare nut wrench. NEVER use an impact wrench on the banjo bolt; shock loading can deform the F00VC01358 control valve inside the injector body.
- Feed tube union nut: 1.5 N·m (13 in·lb) - very light torque; overtightening cracks the injector body.
- Injector hold-down bolt: 18 N·m + 60° angle (Bosch CRIN standard; verify against FAW service manual for the specific CA4DC variant).
- Mandatory FAW service tool coding after installation - the IMA calibration code stamped on the solenoid connector cap must be written to the engine ECU. Failure to code results in persistent P201C / P201D codes, rough idle, and black smoke under load.
- After reinstallation, run an injector leak-back test: return flow at idle should be < 25 mL/min at 800 bar.
- Use NEW copper sealing washers and NEW O-rings on every reinstallation; reused seals take a compression set and leak combustion gases.
- Depressurize the fuel system via the lift pump and disconnect the battery before removing the electrical connector.
- Clean the injector bore with a reamer before inserting the new injector; debris in the bore is the #1 cause of combustion gas leakage.
- Verify FAW IMA code format: The 4-digit IMA calibration code on the 0445110386 body is engine-specific (FAW CA4DC family) - codes 6xxx and 7xxx are valid; codes starting with 8/9 are for the later CA6DL3 series and will trigger P201C immediately. Cross-check the code with the dealer before ECU programming; do not enter a guessed code. Confirm the injector hold-down bolt is torqued to 18 N·m + 60° angle before first start.
Frequently Asked Questions
What vehicles does BOSCH 0445110386 fit?
The 0445110386 fits FAW (China FAW Group) commercial vehicle diesel platforms fitted with the CA4DC engine family. Common applications include FAW light commercial trucks, FAW pickup trucks, BAW (Beijing Automobile Works) light commercial vehicles, and some cross-platform compatibility with YUCHAI applications. The valve group (F00VC01358) is shared with sister SKUs 0445110291, 0445110359, 0445110358, 0445110366, 0445110367, 0445110396, and 0445110434. Do not confuse with JMC JX4D24 2.4L TDCI applications, which use a different injector family. Always verify by the Bosch P/N stamping (0 445 110 386) on the solenoid connector cap before ordering.
What control valve is on the BOSCH 0445110386?
The 0445110386 is fitted with the Bosch F00VC01358 solenoid control valve (F00VC013xx series, CRI2/0445110 platform). The valve code is stamped on the solenoid connector cap (top of the injector body, just below the electrical pins). Do not confuse F00VC01358 with F00VC01328 (which is the control valve used on 0445110387 for JMC JX4D24) - the F00VC01358 and F00VC01328 are NOT interchangeable valve groups.
Is 0445110386 the same as 0445110291?
Both SKUs share the F00VC01358 valve group and the DLLA155P-series nozzle family, suggesting they are sister SKUs on the FAW CA4DC platform. Each carries a different IMA calibration code stamped on the solenoid body - they are NOT directly interchangeable without ECU re-coding. Verify the Bosch P/N stamping (0 445 110 386 for 0445110386 vs 0 445 110 291 for 0445110291) and the IMA code on the failed injector before installation.
What are the symptoms of a failing 0445110386 on FAW CA4DC?
Common failure symptoms on FAW CA4DC platform: (1) OBD fault codes P0201-P0204 - injector circuit malfunction on cylinders 1-4 with P201C/P201D for IMA calibration errors on the F00VC01358 valve; (2) cold-start misfires (most-affected on FAW inline-4 inline-6 configurations); (3) black smoke on acceleration combined with 12-18% fuel consumption increase; (4) hard cold start with delayed smoke (rail pressure build slow); (5) excessive return flow at idle > 80 mL/min confirms internal valve or nozzle leakage. Diagnose on a CRD-700 or EPS200A test bench, then a FAW service tool cut-out test before condemning the injector. Field reports are limited because the platform is CN-market specific.
What is the correct installation torque and procedure for the 0445110386?
Three torque locations on the FAW CA4DC platform: (1) High-pressure fuel line banjo bolt (rail side): 22-25 N·m with a dedicated 14 mm or 17 mm flare nut wrench; NEVER use an impact wrench; (2) Injector hold-down bolt: 18 N·m + 60° angle (Bosch CRIN standard); (3) Feed tube union nut: 1.5 N·m (13 in·lb). Tools: 14/17 mm flare nut wrench, 10/12 mm sockets, calibrated 3-30 N·m torque wrench. Always fit new copper sealing washers + new O-rings.
Does the 0445110386 require IMA / FAW service tool coding after installation?
Yes. The 0445110386 is a complete solenoid common rail injector with cylinder-specific IMA values stored in the engine ECU. After installation, use the FAW official workshop scanner or compatible aftermarket scanner with FAW coverage (e.g. iCarsoft i950, Autel MaxiDAS with FAW vehicle add-on) to code the injector's IMA values. Common installation mistakes: (a) installing the injector without coding, resulting in cylinder imbalance; (b) entering wrong cylinder number; (c) using the wrong IMA value - the IMA code for 0445110386 is on the injector label. NOTE: FAW service tool coverage in aftermarket is limited; consult an authorised FAW service centre if IMA coding equipment is unavailable.
What warranty terms apply to the BOSCH 0445110386?
Standard aftermarket warranty is 12 months from date of purchase, covering manufacturing defects only (no atomisation, no electrical continuity, or > 80 mL/min return flow at 200 bar bench test). Return conditions: (1) manufacturing defect confirmed by bench test; (2) incorrect fitment confirmed before installation - if the injector does not match the build plate stamping (0 445 110 386); (3) physical damage in shipping - photograph before installation. Non-returnable conditions: (1) installed and coded to ECU; (2) damage from fuel contamination (water, debris, algae); (3) over-torqued HP banjo bolt cracking the injector body.
What is the most common ordering mistake for the 0445110386?
Three frequent mistakes: (1) Confusing with 0445110225 (Ford Transit VN/SA 2.4L Duratorq) - different F00VC01336 valve group, NOT 0445110386. (2) Confusing 0445110386 with sister 0445110387 (JMC JX4D24 platform) - DIFFERENT valve group (F00VC01328 vs F00VC01358), even though Bosch P/Ns look similar. (3) Confusing with 0445110291 (FAW CA4D sister) - same F00VC01358 valve group but different IMA range; verify by stamping on the failed injector.
Diagnostic Trouble Codes & Fault Protocols
Common diagnostic trouble codes (DTCs) triggered when this common rail injector experiences wear, circuit faults, or calibration drift:
Fuel Rail / System Pressure Too Low
Excessive internal backleak from worn control valve seats drops common rail pressure below target under engine load.
Injector Circuit Malfunction / Open Circuit
Solenoid coil resistance drift (0.2-0.5 Ω) or piezo stack degradation triggers driver stage shutdown on affected cylinders.
Cylinder Misfire & Balancing Deviation
Carbon-clogged nozzle spray holes or missing IMA calibration causes uneven cylinder contribution. Recode ECM and verify washer seating.
Fuel Rail / System Pressure Too High
Spill line backpressure or stuck metering valve prevents rail depressurization, creating overpressure risks under load.
Cross-Reference & Compatibility
Sister parts, same-platform variants, and known incompatibilities.
