Description
Engine Control Unit BOSCH for Peugeot 307 1.4 HDI.
This used Bosch EDC16C3 engine control unit is a direct-fit electronic control module commonly found in Peugeot 307 1.4 HDi applications. It is offered for professional mechanics and experienced DIYers who search by product code (0281011090, 9654984380, etc.). The unit manages fuel injection timing, boost control and engine diagnostics to maintain efficient combustion, low emissions and drivability for the 1.4 HDi diesel engine.
Technical Information
- Manufacturer: BOSCH
- Model: EDC16C3 Engine Control Unit
- Product Codes: 0281011090
- Additional Numbers: 9654984380, 9647785580, 1940WN, 1940WP, NFP
Compatibility
Designed for Peugeot 307 1.4 HDi. May also be used in other PSA vehicles equipped with the 1.4 HDi (DV4) family of engines where the listed product codes match. Always verify the unit part numbers printed on the ECU before installation to ensure proper fitment.
What This Unit Does
The ECU monitors and controls injector timing, common-rail pressure, EGR and turbo actuation (where applicable), interprets sensor inputs (MAP, MAF, crank/cam position, coolant temperature, intake temperature, etc.) and stores fault codes for diagnostics. Correct operation is essential for fuel economy, emission control and reliable engine operation.
Installation
General replacement steps for experienced technicians:
- Disconnect the negative battery terminal before starting work.
- Locate and remove the ECU (location varies by model — often in the engine bay or behind the glovebox).
- Unplug all electrical connectors carefully, releasing any locking tabs; avoid pulling on wiring harnesses.
- Remove mounting bolts and extract the unit. Fit the replacement unit and tighten bolts to the manufacturer’s torque specification.
- Reconnect connectors and the battery. Some replacements require coding or initialization before the engine will run correctly.
Installation and Coding – Important
- – The Unit Is Used And Is “Paired” With The Original Vehicle (VIN/PIN/Keys).
- – Options For Commissioning:
- 1) Cloning Data From The Old Unit (EEPROM/Flash) – After Cloning The Unit Is Plug And Play.
- 2) Virginization And Subsequent Initialization/Telecoding Via DiagBox (Or Online) + Key Adaptation.
- – It Is Recommended To Be Performed By A Specialist With PSA Service Equipment (DiagBox/Lexia/PP2000).
- – Always Disconnect The Battery Before Dismantling/Installing And Follow The Manufacturer Procedure To Avoid Damage To The Unit.
Recommended For Installation
Have the unit cloned or coded by a technician with PSA diagnostic tools if required. Protect connectors from dirt and moisture, ensure pin terminals are straight and clean, and verify power/ground circuits before first start. Do not open the ECU housing; this risks damage and loss of calibration.
Why This Part Most Often Fails
- Water ingress and corrosion of connector pins or PCB traces (common when the ECU mounting area is exposed to leaks or spray).
- Thermal stress and repeated heating/cooling cycles that cause solder joint cracks or component failures.
- Electrical surges from a faulty alternator, poor battery connections or jump-start events that damage onboard electronics.
- Connector damage, pin corrosion or poor grounding causing intermittent faults and ECU malfunctions.
Why Choose This Unit
Replacing a faulty ECU with a unit carrying the correct Bosch product codes restores engine management functions and error-free communication with diagnostics tools. For technicians, searching by the OEM part number (0281011090 / 9654984380) is the fastest way to locate the correct unit.
