Delphi DCM3.5 ECU BG91-12A650-FGB – what to know
Unit BG91-12A650-FGB (Delphi 28354071) controls the 2.0 TDCi engine in Ford cars. We test every unit before sending it to the customer.
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-FGB and Delphi 28354071 must match your unit. If in doubt, send us a photo of the label before ordering.
