Description
Engine Control Unit BOSCH ME7.4.4 NFU. It is for Peugeot 307 1.6 16V NFU 80 kW.
Original Bosch ME7.4.4 engine control unit designed for vehicles equipped with the 1.6 16V NFU (80 kW) engine. Commonly referenced by product codes 0261207474 and 9650346080, this ECU is suitable for mechanics and experienced DIY enthusiasts who need a reliable control unit replacement for Peugeot (and some Stellantis) models. The unit controls fuel injection, ignition timing and emissions parameters to ensure smooth running and optimal performance of the NFU engine.
Key advantages: precise engine management calibrated by Bosch, direct compatibility with NFU engine wiring and sensors, and recognition in common parts searches by reference numbers (0261207474, 9650346080). Ideal when the original ECU shows faults such as no-start, misfiring, or erratic behavior linked to the control electronics.
Technical Information
- Manufacturer: Bosch
- Model: ME7.4.4 NFU
- Product Codes: 0261207474, 9650346080
- Other Numbers: 1942E4, 1940V8, NFP
Compatibility
Fits: Peugeot 307 with 1.6 16V NFU engine (80 kW). May also be used in related Stellantis applications that share the NFU engine control specifications. Verify engine code NFU on the vehicle before installation.
Installation And Coding – Important
- The unit is used and is “paired” with the original vehicle (VIN/PIN/keys).
- Options to commission the unit:
- Cloning data from the old unit (EEPROM/Flash) – after cloning the unit is plug and play.
- Virginization and subsequent initialization/telecoding via DiagBox (or online) + key adaptation.
- Recommended to be performed by a specialist with PSA service equipment (DiagBox/Lexia/PP2000).
- Always disconnect the battery before removal/installation and follow the manufacturer procedure to avoid damaging the unit.
Recommended Installation
Preparation: Park on a level surface, remove ignition key, and disconnect the negative battery terminal. Locate the ECU (consult vehicle service manual for exact location). Carefully unplug all connectors, mark them if necessary, and remove mounting bolts. Install the replacement unit in reverse order using original connectors and secure mounting. After mechanical installation, perform cloning or coding as required (see Installation And Coding section). Finally, reconnect the battery and carry out a full system check and test drive to confirm correct operation.
Why This Part Fails Most Often
Common failure causes include water ingress or corrosion of connectors, thermal stress and solder joint fatigue, electrical surges from a failing alternator or jump-starts, and physical damage from improper handling. Failures often present as no-start, intermittent stalling, misfires, or fault codes related to fuel injection and ignition. In some cases, immobilizer or key-pairing issues prevent engine start until the ECU is properly cloned or coded.
Practical Tips For Mechanics And DIYers
- Check wiring, grounds and sensor signals before replacing the ECU to avoid unnecessary unit swaps.
- Use anti-static precautions and avoid touching PCB contacts. Keep the unit dry and protected during work.
- If you lack DiagBox-level tools, consider professional cloning or coding services to ensure immediate plug-and-play operation.
