What happens after purchase
Once you have placed your order, send us the car’s VIN. We prepare the ECU with data from the Ford server and load the latest software – this service costs nothing extra.
The ECU is not plug & play. After fitting, the keys and VIN must be assigned in the PATS procedure using FORScan or Ford IDS. The warranty is 6 months.
When the ECU may be faulty
An engine ECU failure may show up as:
- no start and no signal at the injectors,
- the diagnostic tool cannot connect to the ECU,
- the ECU gets no power even though the fuses are OK,
- problems after water damage or a short in the wiring.
Faults in the wiring, power supply or sensors can cause similar symptoms, so run a diagnosis before you buy.
How to check compatibility
The safest way is to compare labels. If your ECU shows number BG91-12A650-RF and number 28306977, it is the same version – whatever the Ford model and year, as this number may appear in different cars. If the sticker is hard to read or you have questions, send us a photo of it before buying.
