How to choose ECU BG91-12A650-SE for your Ford
This is a Delphi DCM3.5 engine control unit with Ford number BG91-12A650-SE and number 28298181, used in Ford vehicles with the 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.
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-SE and Delphi 28298181 must match your unit. If in doubt, send us a photo of the label before ordering.
