The Bosch 0445110239 is an OEM common rail diesel fuel injector engineered for Ford / PSA / BOSCH passenger and commercial vehicles powered by the Puma 2.2 TDCi / HDi diesel engine. Operating at a peak rail pressure of 1600 bar, this unit features the high-precision DLLA153P1488 nozzle assembly and F00VC01334 valve mechanism to deliver multiple micro-injections per combustion cycle. It fully complies with Euro 4 emissions standards. Direct replacement for OEM references 6C1Q-9K546-AC, 1378432, 1495919, 1980 J7, 9659228980, 0986435165.
Always verify the OE cross-reference stamped on your failed injector body (6C1Q-9K546-AC / 1378432) prior to ordering. Bosch 0445110239 utilizes the F00VC01334 control valve and DLLA153P1488 nozzle assembly calibrated to 1600 bar. Cylinder-specific IMA coding is mandatory after installation.

Installation Tips
Tools needed: 10mm & 11mm flare nut wrench (rail and injector inlet unions), Injector slide hammer / mechanical puller kit (if seized), Injector seat cleaning brass brush set & industrial vacuum, Seat reaming tool (if carbon erosion is present), Torque wrench (2 N·m - 40 N·m range), ECU diagnostic scan tool with IMA/QR coding capability, Digital micrometer / depth gauge for copper washer check
- Disconnect Battery & Relieve Rail Pressure: Isolate negative battery terminal and verify rail residual pressure drops below 10 bar via live diagnostics before cracking fuel fittings.
- Clean Engine Bay & Injector Recesses: Thoroughly blast away grit, oil slurry, and loose dirt around cylinder head injector wells using compressed air and degreasing solvent.
- Label Wiring Harness & Spill-Off Connectors: Tag each cylinder harness connector and gently disengage delicate plastic spill-off return rail clips.
- Remove High-Pressure Supply Lines: Back off high-pressure union nuts with a flare-nut wrench; IMMEDIATELY cap all open fuel rail orifices and injector inlets with clean blanking caps.
- Extract Hold-Down Clamp Fasteners: Back out hold-down clamp bolts. Note that torque-to-yield stretch bolts must always be discarded and never reused.
- Extract Injector Body: Withdraw injector vertically. If carbon-bonded or coked, attach an approved mechanical slide-hammer puller to the inlet adaptor without rotating the injector body.
- Inspect Injector Well & Bore: Ensure old copper seal washer has not remained fused at the base of the cylinder head seat; remove with a brass retrieval pick if stuck.
- Clean & Ream Injector Seat: Ream and burnish injector seating face using dedicated seat cutter brushes and industrial vacuum until seat is 100% bare, flat metal.
- Install New Copper Sealing Washer: Mount an OEM-specification copper washer of designated thickness (standard 1.5mm-2.0mm) using high-temp grease to hold in position.
- Fit Injector with Ceramic Anti-Seize: Lightly coat the injector body barrel with approved high-temperature ceramic grease; keep nozzle tip and copper washer strictly dry and clean.
- Torque Hold-Down Clamp to Spec: Secure hold-down clamp bolts and torque to factory specified stages (22 N·m) using a calibrated torque wrench.
- Refit High-Pressure Delivery Pipes: Thread union nuts by hand to avoid cross-threading, then tighten injector inlet and rail unions to 28-30 N·m evenly.
- Reconnect Return Leak-Off Line & Harness: Push on leak-off return clips until retaining collars click home; reattach electrical plug and lock harness tab firmly.
- ECU IMA / QR Code Calibration & Fuel Priming: Program the unique alphanumeric IMA/QR calibration code etched on the injector head into the corresponding ECU cylinder address; prime fuel system prior to initial cranking.
- CRITICAL IMA CALIBRATION: Never operate the engine without programming the new IMA/QR trim code into the ECU map — uncalibrated injectors cause combustion knocking, cylinder imbalance, and premature DPF clogging.
- CRITICAL COPPER WASHER REPLACEMENT: Always install brand new copper crush washers and torque-to-yield clamp bolts — reusing old seals leads to catastrophic combustion gas leakage ('black death' buildup).
- HOSPITAL-GRADE FUEL CLEANLINESS: A microscopic contamination particle as small as 5 microns can jam the internal F00VC01334 valve or needle — ensure all fuel line plugs stay on until final connection.
- STRICT HOLD-DOWN TORQUE: Adhere strictly to the 22 N·m tightening sequence — overtightening distorts the injector body and binds the needle.
Frequently Asked Questions
Does Bosch injector 0445110239 require ECU coding (IMA / QR code)?
Yes, Bosch injector 0445110239 requires cylinder-specific IMA calibration code programming into the engine control unit (ECU). Each unit has a unique multi-character calibration code stamped on its electrical connector body or solenoid head that defines fuel delivery tolerances across multiple rail pressure points. Programming this code via a diagnostic scanner (VCDS, ODIS, INPA/ISTA, or Autel MaxiSys) is mandatory to ensure balanced cylinder idle, proper emissions compliance, and smooth throttle response.
What are the most common symptoms of a failing 0445110239 injector on Ford / PSA / BOSCH Puma 2.2 TDCi / HDi?
Common symptoms include prolonged cold-start cranking, rough or oscillating idle, black exhaust smoke under acceleration (nozzle needle wear/over-fueling), white smoke on startup (unburnt fuel spray), ticking/clattering under load, increased fuel consumption, cylinder misfire trouble codes (P0300-P0306), and high fuel spill-off return rates causing low rail pressure codes under heavy acceleration.
Should I replace injectors individually or as a complete set?
While replacing a single failed injector is acceptable if fuel contamination is ruled out, industry best practice on engines with over 150,000 km is to replace or bench-test all injectors as a complete set. Wear across the high-pressure control valve (F00VC01334) and nozzle (DLLA153P1488) occurs evenly across all cylinders; fitting one new unit alongside three or five worn units often leads to noticeable idle vibration due to delivery quantity variance.
Why must the copper crush washer and hold-down bolt be replaced on every install?
The copper washer forms the critical gas-tight seal between the injector nozzle and the cylinder head combustion chamber. During combustion, temperatures exceed 1,500°C and pressures surpass 150 bar. A compressed washer work-hardens and will not re-seal properly. Furthermore, most hold-down clamp bolts are torque-to-yield (stretch) fasteners designed for single use; reusing them risks bolt snapping inside the cylinder head or loss of clamp tension.
What preventative maintenance is required after installing replacement 0445110239 injectors?
Always replace the diesel fuel filter with a high-efficiency OEM-spec filter (3 to 5 micron rating), inspect the fuel tank and fuel lines for metallic swarf from high-pressure pump wear, flush the common rail if debris is present, use high-quality EN590 diesel, and verify injector smooth running balance values with diagnostic software after 500 km of driving.
