Delphi DCM3.5 ECU BG91-12A650-NE – what to know
Unit BG91-12A650-NE (Delphi 28297065) controls the 2.0 TDCi engine in Ford cars. We test every unit before sending it to the customer.
Ford number and Delphi number
Both numbers on the label matter when you order:

- Delphi number: 28297065
- ECU type: Delphi DCM3.5
Vehicle compatibility
ECU BG91-12A650-NE may have been fitted to different Ford models, so compatibility is decided by the numbers on the label, not by the model and year of the car. Compare Ford number BG91-12A650-NE and number 28297065 with your ECU. If in doubt, send us a photo of the label before buying.
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.
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.
We describe the replacement and programming in our guide Ford DCM3.5 ECU replacement and VIN programming. Other numbers are in the Ford DCM3.5 ECU collection, and more about the manufacturer on the Delphi page.
