How to choose ECU BG91-12A650-FFB for your Ford
This is a Delphi DCM3.5 engine control unit with Ford number BG91-12A650-FFB and number 28354065, used in Ford vehicles with the 2.0 TDCi engine. The unit is tested before dispatch.
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.
Choose by number, not by model
Fords with the 2.0 TDCi engine used many versions of the DCM3.5 ECU, and one version could go into several models. That is why you should choose the ECU by its numbers only: Ford BG91-12A650-FFB and Delphi 28354065 must match your unit. If in doubt, send us a photo of the label before ordering.
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.
