How to choose ECU BG91-12A650-RG for your Ford
This is a Delphi DCM3.5 engine control unit with Ford number BG91-12A650-RG and number 28316176, 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.
Does this ECU fit your car?
Model and year are not enough, because the same number BG91-12A650-RG may have been fitted to several Ford models. Look at the label of your ECU and check that it shows BG91-12A650-RG and 28316176. Not sure? Send us a photo of the sticker and we will check it before you buy.
