0445110340 Bosch Common Rail Diesel Injector – PSA/Ford 1.6 HDi

The Bosch 0445110340 is a solenoid-type common rail diesel injector engineered for the PSA/Ford 1.6 HDi (DV6) engine family. This unit serves as a direct replacement for OEM references 1980S5 (Citroën/Peugeot), AV2Q9F593BA and 1696927 (Ford), and 9687069280. Operating within the Bosch CRI2-18/20 platform, it delivers precise fuel atomization at rail pressures up to 1,600 bar, supporting the multi-pilot injection strategies required for Euro 4/5 emission compliance in passenger cars and light commercial vehicles.

The 0445110340 injector is calibrated for the DV6 1.6-liter common rail diesel engine, an architecture shared across multiple European brands. Peugeot applications include the 208, 301, 308, Partner, and Expert. Citroën fitments cover the C3, C3 Picasso, C3 Aircross, Berlingo, and Dispatch. On the Ford side, this injector serves the Fiesta, Focus, C-Max, and Transit Connect equipped with the TDCi variant of the same engine. Fiat and Opel/Vauxhall models sharing the PSA platform also accept this part number in select 1.6 HDi applications. This broad interchangeability makes the 0445110340 a high-turnover stocking item for diesel parts distributors serving mixed-fleet repair shops.

Common rail injector replacement demands more than basic mechanical skill-it requires contamination discipline. The DV6 engine's solenoid injector sits beneath the cam cover, sealing directly against the cylinder head via a copper combustion washer. This washer must be replaced at every install; reusing it risks compression leakage and carbon blow-by that destroys the new injector's nozzle within thousands of miles. Before insertion, clean the injector bore with a nylon brush and verify the sealing surface is free of carbon deposits. Lubricate the O-rings with diesel-compatible grease-never engine oil. Tighten the injector clamp to the OEM torque specification in the DV6 repair manual; over-torquing deforms the nozzle body and skews the spray pattern. After installation, code the injector into the ECU using a diagnostic platform (DiagBox, IDS, or equivalent) to prevent rough running and excess smoke.

The 0445110340 belongs to the high-failure segment of common rail diesel components on DV6 engines. Typical workshop observations include hot-start misfires, injector return flow exceeding specification, and cavitation pitting inside the control valve-all of which reduce the effective fuel dose and trigger lean-mixture overheating at the nozzle tip. For diesel repair shops, stocking this reference enables same-day turnaround on jobs that would otherwise wait 48 hours for dealer supply. For parts wholesalers, the PSA/Ford cross-application creates demand from multiple vehicle channels. A remanufactured unit built to OE protocol with new solenoid valve and nozzle offers a cost-effective alternative to dealer parts while restoring idle stability, cold-start performance, and fuel economy to pre-failure levels.

Q1: The 0445110340 and 0445110739 look identical-can I use either?
A: No. While both fit DV6 engines, they carry different ECU calibration codes and flow classifications. Mixing them causes imbalance across cylinders.

Q2: What core evidence do you need to confirm compatibility?
A: Send a photo of the injector label plus the engine code (e.g., 9HP) or VIN. The DV6 family used several injector variants by power output.

Q3: Do remanufactured units include new copper washers and O-rings?
A: Quality suppliers include a seal kit. Confirm this before ordering-reusing seals is the leading cause of post-installation leaks.

Q4: How do I test a suspected 0445110340 before replacement?
A: Return flow testing at operating temperature is the fastest field check. High return volume with hard starting confirms internal wear.

Q5: What fuel quality precautions prevent premature failure?
A: Water contamination and excessive biodiesel accelerate control valve erosion. Install a secondary filter and test fuel samples if repeat failures occur.

Q6: Do you offer batch pricing for workshops stocking multiple references?
A: Yes. Diesel parts distributors and multi-bay shops qualify for tiered pricing on mixed orders of DV6 injectors and CR system components.
