Magneti Marelli 55201829 IAW 5NF.S5 engine control unit for Fiat Panda 169 1.2 8V

The tested 55201829 engine control unit has been prepared for installation and is covered by a warranty. The offered module is supplied in Virgin plug & play condition. It does not contain immobiliser data from the previous vehicle and automatically pairs with the vehicle security system after installation.

Applications of the 55201829 61600.579.03 engine control unit

The 55201829 IAW 5NF.S5 engine control unit is mainly intended for the second-generation Fiat Panda, type 169, fitted with the 1.2 8V FIRE petrol engine. This ECU version is also found in selected configurations equipped with the Dualogic transmission.

  • Fiat Panda II 169
  • 1.2 8V FIRE petrol engine
  • engine capacity: 1242 cm³
  • power output: usually 44 kW / 60 hp
  • engine code: 188A4.000
  • selected versions with Dualogic or automated manual transmission
  • approximate years of application: 2005–2011

This control unit is not automatically suitable for every Fiat Panda with a 1.2 engine. The Fiat Panda 169 was fitted with many different ECU versions depending on the year, transmission, equipment and software version. The most important compatibility criterion is matching the references shown on the original module.

Identification numbers shown on the ECU label

  • 55201829 – Fiat part number
  • 61600.579.03 – Magneti Marelli control unit number
  • 6160057903 – number written without dots
  • IAW 5NF.S5 – engine control unit family
  • IAW5NF.S5 and IAW5NFS5 – alternative forms of the reference
  • HW104 – hardware version
  • 3004-A4W – software identification
  • D032 – module variant designation

The safest way to select the correct part is to match both the 55201829 and 61600.579.03 numbers. IAW 5NF.S5 control units with a different Fiat part number or software version should not be treated as direct replacements without prior verification.

Common symptoms of a faulty IAW 5NF.S5 engine control unit

  • the engine does not start even though the starter motor operates correctly,
  • the vehicle stalls after the engine or control unit has warmed up,
  • intermittent or complete loss of communication with the ECU,
  • the ignition coils or fuel injectors are not being controlled,
  • uneven engine operation and recurring misfires,
  • problems with throttle body or accelerator pedal control,
  • the engine warning light or immobiliser warning light comes on,
  • internal EEPROM memory, processor or output stage faults are stored.

Similar symptoms may also be caused by damaged wiring, connectors, ignition coils, fuel injectors, the throttle body, sensors, poor ground connections or incorrect power supply. Before replacing the control unit, the electrical system should be checked and a complete vehicle diagnosis should be carried out.

FAQ about the Fiat Panda 55201829 IAW 5NF.S5 engine control unit

Is the 55201829 ECU suitable for a Fiat Panda 1.2 8V?

Yes. Part number 55201829 is used in selected versions of the Fiat Panda II 169 with the 1.2 8V petrol engine. Before purchasing, also compare the 61600.579.03, IAW 5NF.S5 and HW104/3004-A4W references.


Is the 61600.579.03 ECU compatible with a Fiat Panda 1.2 Dualogic?

The 61600.579.03 engine control unit is found in selected Fiat Panda 1.2 configurations with the Dualogic transmission. Final compatibility depends on the complete references of the original ECU, the software version and the vehicle equipment.


Does the IAW 5NF.S5 HW104 ECU require immobiliser coding?

The offered IAW 5NF.S5 HW104 module is prepared in Virgin plug & play condition. After installation, it automatically pairs with the vehicle immobiliser system, so manual coding or cloning is not normally required.


Can the Fiat Panda 55201829 ECU be installed without the original control unit?

Yes. No data reading from the damaged control unit is required to start the 55201829 Virgin version. However, the part numbers and software version must match the module originally installed in the vehicle.


Are the 55201829 and other IAW5NFS5 control units interchangeable?

Not always. The IAW5NFS5 designation alone does not guarantee compatibility. The Fiat part number, Magneti Marelli number, hardware version, software identification and transmission type must all be compared. The safest solution is to use an ECU with the same references as the original part.
