Applications of the 8200181486 IAW 5NR2.T1 ECU
This engine control unit is mainly intended for selected versions of the following vehicles:
- Renault Clio II 1.2 16V – models from the early 2000s, approximately 2001–2005,
- Renault Twingo I 1.2 16V – selected versions manufactured during a similar period,
- 1.2 16V petrol engine with a capacity of 1149 cm³,
- engines from the D4F family, depending on the vehicle version.
Renault used several similar control units from the IAW 5NR2 family. Compatibility should therefore not be determined solely by the vehicle model, engine capacity or the appearance of the housing. Before purchasing, compare the references 8200181482, 8200181486, 16481134, 16514634 and the IAW 5NR2.T1 designation with the original module removed from the vehicle.
Possible symptoms of a faulty Renault 1.2 16V ECU
- the engine does not start even though the starter motor operates correctly,
- no diagnostic communication with the engine control unit,
- the engine warning light does not illuminate after switching on the ignition,
- no control signal to the ignition coils or fuel injectors,
- the vehicle stalls or the engine runs unevenly,
- internal faults relating to the IAW 5NR2.T1 module,
- the immobiliser does not authorise engine start.
Before replacing the ECU, it is advisable to check the power supply, ground connections, electrical wiring, ignition coils and communication with the immobiliser. A damaged wiring harness or faulty actuator can cause symptoms similar to those of a defective engine control unit.

Is the 8200181482 ECU compatible with the Renault Clio II 1.2 16V?
Yes, the 8200181482 ECU was used in selected versions of the Renault Clio II 1.2 16V. Before purchasing, also confirm the 8200181486 reference and the exact IAW 5NR2.T1 designation.
Does the 8200181486 engine ECU require coding?

The IAW 5NR2.T1 module is used in selected Renault Twingo I versions with a 1.2 petrol engine. Compatibility must be confirmed using the 8200181482, 8200181486, 16481134 and 16514634 references.
Do the 16481134 and 16514634 references identify the same Renault ECU?
These are Magneti Marelli references shown on the label of the offered control unit. They should be compared together with the Renault part numbers and the IAW5NR2T1 designation, as a single reference is not always sufficient to select the correct ECU.
