Delphi DCM3.5 ECU BG91-12A650-FJB – what to know
Unit BG91-12A650-FJB (Delphi 28362911) controls the 2.0 TDCi engine in Ford cars. We test every unit before sending it to the customer.
How to check compatibility
The safest way is to compare labels. If your ECU shows number BG91-12A650-FJB and number 28362911, 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.
Ford number and Delphi number
Both numbers on the label matter when you order:
- Ford number: BG91-12A650-FJB / BG9112A650FJB
- Delphi number: 28362911
- ECU type: Delphi DCM3.5
Preparation and fitting
- After purchase, send us your VIN – we prepare the ECU with data from the Ford server and the latest software. This service is included in the price.
- The ECU is not plug & play: after fitting it requires PATS programming (keys and VIN) with FORScan or Ford IDS.
- Warranty: 6 months.
Symptoms that may point to an ECU failure
- Diagnostics cannot connect to the ECU.
- The engine will not fire, the injectors get no signal.
- The fault appeared after water got in or after a short in the harness.
- The ECU has no power despite working fuses.
Keep in mind that the cause may also be the wiring, the power supply or a sensor. Diagnose first, then buy.
