Vehicle Compatibility
- Fiat Punto – selected versions with the 1.2 8V petrol engine, Euro 6, without Start & Stop.
Before ordering, compare part number 51987310, designation 9GF.TH and hardware version HW003 with the label on your original ECU. It is also advisable to check the software reference 4E03_L18 and the additional marking BC.0116768.C.
Matching the engine capacity or the 9GF ECU family alone is not sufficient to confirm compatibility. If the numbers or variant of your original ECU are different, send us a photo of its label together with the VIN so that compatibility can be checked before purchase.
Virgin Preparation and Installation
This ECU is supplied in Virgin condition, with its previous vehicle assignment cleared. Once installed, it automatically pairs with the immobilizer system of a compatible vehicle.
For Plug & Play operation, the ECU must be correctly matched to the vehicle, the immobilizer must be functioning properly and communication between the ECU and the vehicle must be correct. When these conditions are met, the ECU is paired automatically without separate immobilizer programming using diagnostic equipment.
The immobilizer remains active. The Virgin configuration is not intended to bypass immobilizer faults.
