Technical Information

• Manufacturer: Bosch
• Model: ME7.4.4 NFU
• Product Codes: 0261207474, 261207474
• Additional Numbers: 9650346080, 1942E4, 1940V8, NFP, ME7.4.4

Compatibility And Application

Primarily fitted to Peugeot 307 1.6 16V with engine code NFU (80 kW). The same ECU platform can be found across related Stellantis petrol engines; always verify the engine code stamped on the engine or printed on the original ECU label when selecting a replacement.

Installation Recommendations

• Prepare: Park on a flat surface, switch off ignition and remove the key. Disconnect the negative battery terminal and allow the vehicle to sit for a few minutes to remove residual voltage.
• Access: Remove necessary trim and ECU cover to access the control unit. Handle connectors carefully—do not bend pins or force plugs.
• Replacement: Unbolt the ECU from its mount, unplug all electrical connectors and install the replacement unit in reverse order. Ensure connectors seat fully and locking tabs engage.
• Programming: After physical replacement the ECU will typically require software flashing/coding and immobilizer pairing or adaptation using appropriate diagnostic equipment. Reprogramming must be performed by a workshop with suitable Bosch/PSA tools or diagnostics capable of writing the correct firmware and immobilizer data.
• Safety: Observe electrostatic discharge (ESD) precautions. Avoid working in wet conditions and keep the ECU and connectors clean and dry.

Why This Part Commonly Fails

Engine control units are designed for long service life, but failures can occur due to external stresses rather than simple wear. The most frequent causes include water ingress or corrosion (from leaks or condensation), thermal cycling that stresses solder joints, voltage spikes from poor electrical connections or jump-starting, and damage from contaminated connectors. Faulty sensors, short circuits or persistent electrical faults elsewhere in the vehicle can also overload the ECU and lead to failure. Symptoms of a failing ME7.4.4 ECU include engine running irregularly, frequent limp-home mode, failure to start, random fault codes and poor fuel economy.

Why Choose This Unit

For mechanics seeking an ECU replacement that matches original Bosch specifications, this ME7.4.4 unit carries the familiar PSA part numbers and is suitable for workshops and experienced DIYers who can handle programming. Using the correct part number (e.g., 0261207474 / 9650346080) improves the chance of direct compatibility with the vehicle wiring and sensor set.
