Choosing the Correct ECU for Fiat Punto 1.2 8V Euro 6
The label on ECU 52013987 indicates variant 9GF.TH/HW003 for the 1.2 8V Euro 6 petrol engine without Start & Stop. Additional references on this unit are BC.0116768.E and 4E04-_L20.
Vehicle Compatibility
- Fiat Punto – selected versions with 1.2 8V petrol engine, Euro 6, without Start & Stop.
Compare part number 52013987, variant 9GF.TH and hardware designation HW003 with the label on your original ECU. Also check the software references and the indication that the unit is intended for a version without Start & Stop.
Matching the vehicle model, engine capacity or 9GF ECU family alone is not sufficient to confirm compatibility. If the markings differ, send us a photo of the old ECU label together with the VIN for verification before ordering.
Possible Symptoms Requiring ECU Diagnosis
Checking the ECU may be appropriate if you experience:
- engine misfires after the spark plugs, ignition coils and wiring have been checked;
- incorrect injector control after ruling out a faulty injector and problems in its electrical circuit;
- incorrect response to the accelerator pedal after checking the pedal, throttle body and wiring.
These are examples of situations that may require further diagnosis and are not confirmed common faults of the 9GF.TH variant. Before replacing the ECU, it is important to determine whether the problem is caused by the ECU itself or by another component working with it.
Virgin Plug & Play Preparation and Installation
This ECU is supplied in Virgin condition, with its previous vehicle assignment cleared. Once installed in a compatible vehicle, it automatically pairs when the immobilizer is functioning correctly and communication between the vehicle modules is operating properly.
Automatic pairing does not require immobilizer data to be copied from the old ECU. The immobilizer remains active, and Virgin preparation does not change the ECU's intended application for the 1.2 8V Euro 6 version without Start & Stop.

No immobilizer data needs to be copied from the old ECU with the Virgin version offered here. Automatic pairing requires a compatible ECU, a correctly functioning immobilizer and proper communication with the vehicle.

Does the Virgin version have the immobilizer disabled?
No. The ECU is prepared to pair with the vehicle's immobilizer, which remains active. This is not an IMMO OFF version.
