How to choose ECU BG91-12A650-FFD for your Ford
This is a Delphi DCM3.5 engine control unit with Ford number BG91-12A650-FFD and number 28362908, used in Ford vehicles with the TDCi (most often 2.0 TDCi) engine. The unit is tested before dispatch.
Typical symptoms of a faulty DCM3.5 ECU
A damaged ECU can stop the engine from starting because the injectors receive no signal. The tester then cannot connect to the unit, and a measurement may show no power at the ECU despite good fuses. The failure can follow water ingress or a short circuit in the wiring.
The same symptoms can, however, come from a fault in the harness, power supply or sensors, so run a diagnosis before you buy an ECU.
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.
Ford number and Delphi number
Both numbers on the label matter when you order:
- Ford number: BG91-12A650-FFD / BG9112A650FFD
- Delphi number: 28362908
- ECU type: Delphi DCM3.5
Choose by number, not by model
Fords with the TDCi (most often 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-FFD and Delphi 28362908 must match your unit. If in doubt, send us a photo of the label before ordering.
Before fitting, it is worth reading our guide Ford DCM3.5 ECU replacement and VIN programming. If your ECU has a different number, check BG91-12A650-FFF (28459226), BG91-12A650-FGB (28354071), BG91-12A650-FGD (28362914), BG91-12A650-FGE (28403828) or the whole Ford DCM3.5 ECU collection.
