Delphi, FoMoCo, Continental and Bosch ECUs for Ford
We supply used Ford engine control units, checked before dispatch, for passenger cars and light commercial vehicles. More than 100 of them are Delphi DCM3.5 units for 2.0 TDCi engines. The range also includes original FoMoCo ESU-312, ESU-411 and ESU-412 modules, Continental SID206 and SID212EVO units and individual Bosch ECUs, for example for the EcoSport 1.5 TDCi.
How to choose the right Ford engine ECU
The most reliable method is to compare the full numbers on the label of your original unit. Before ordering, check:
- the Ford part number in the XXXX-12A650-XX format, e.g. AG91-12A650-ZG or JK21-12A650-AB, including the letter suffix,
- the manufacturer number, e.g. Delphi 28278423, Continental A3C01265902 or Bosch 0281033076,
- the ECU family, e.g. DCM3.5, SID212EVO or ESU-412, if shown on the label,
- the engine code and capacity, and the gearbox type,
- the preparation stated in the offer – usually "ready for programming".
On Ford vehicles, the letters at the end of the part number define the software. The same Delphi base number can appear with different Ford references – for example 28270050 as AG91-12A650-AEF and AG91-12A650-ZF – so always compare both numbers. The VIN helps identify the vehicle version, but it does not replace the number on the ECU label.

Delphi DCM3.5 ECUs for Ford 2.0 TDCi
DCM3.5 is the largest group in this category – more than 100 units for Ford 2.0 TDCi engines, including the Focus, C-Max, Mondeo, S-Max, Galaxy and Kuga. They differ in Ford number and software version, so we have grouped them all in the Ford DCM3.5 2.0 and 2.2 TDCi collection, where a specific number is easier to find. DCM3.5 units are supplied ready for programming – after installation they need the correct software and vehicle configuration, followed by PATS adaptation.
Programming, PATS and cloning
A used Ford ECU contains data from its previous vehicle, so it will not start the engine straight after connection. The preparation depends on the ECU family and is stated in the product description.
- Ready for programming – the standard version: after installation the workshop loads the software, writes the VIN and configuration, e.g. with FORScan or Ford IDS, provided the tool supports the vehicle.
- PATS adaptation – pairing the ECU with the immobiliser; on some models the procedure may require two working keys.
- Cloning – for selected offers we can transfer data from your old ECU to the replacement on request; this depends on the condition of the memory and processor in the damaged unit.
Before ordering, make sure your workshop has a suitable interface and software for your model.

Symptoms of a faulty engine ECU
The most commonly reported problems are: the engine does not start, no diagnostic communication with the ECU, engine cut-outs while driving, limp mode, PATS faults with a flashing immobiliser light, and multiple unrelated sensor faults at once. The same symptoms can also come from the power supply, earth connections, wiring, sensors or other modules, so we recommend a vehicle diagnosis before buying. Read more in our guide Faulty engine control unit (ECU) symptoms. If diagnostics point to another module, see Ford ABS pumps and Ford BCM, GEM and SJB modules.
Testing, warranty and delivery
Every ECU is bench-tested before dispatch – connected to a power supply and diagnostic tools outside the vehicle. Testing the unit does not replace a diagnosis of your car. Warranty terms are given in the product description; more information is available on our returns and complaints, shipping costs and delivery times and payment methods pages.
