8586766 0281031944 – Bosch DDE engine control unit for BMW and MINI
Original, tested Bosch engine control unit designed for selected BMW and MINI diesel vehicles. The module is fully functional, but it requires the appropriate programming for the specific vehicle before installation.
Application of the 0281031944 control unit
- BMW 2 Series Active Tourer F45 – selected 216d 1.5 diesel versions with the B37C15A engine, five-door body, confirmed application in vehicles from approximately 2014–2015,
- MINI Hatch F55 – selected One D and Cooper D 1.5 diesel B37C15A versions, five-door body, early production years from approximately 2014,

Compatibility may depend on the software version, vehicle equipment and drivetrain configuration. Before purchasing, compare the references DDE 8 586 766-01, 0 281 031 944 and 1039S80802 with the label on the original control unit. The vehicle model, year and engine capacity alone are not sufficient to confirm compatibility.
Common symptoms of an engine control unit failure
- no diagnostic communication with the DDE module,
- engine does not start or stalls while running,
- injector circuit fault codes,
- incorrect control of the throttle or regulating valve,
- limp mode and reduced engine power,
- intermittent starting problems or loss of control over actuators.
Similar symptoms can also be caused by faults in the electrical system, power supply, ground connections, communication bus or engine components. ECU replacement should always be preceded by a thorough vehicle diagnostic check.
Frequently asked questions
Does the 8586766 control unit fit every BMW F45 216d?
No. This control unit is used only in selected BMW 2 Series Active Tourer configurations. Before purchasing, the complete set of part numbers should be compared and compatibility with the software version of the original ECU should be confirmed.
Will the Bosch 0281031944 start the vehicle immediately after installation?
No. The offered module requires prior programming, cloning or synchronisation with the vehicle electronics. Simply connecting the unit is not enough to start the engine.
Can the DDE 8 586 766-01 control unit be cloned?
Yes, provided that the memory of the original ECU can be read correctly. Complete cloning makes it possible to transfer the software, configuration and data required for start authorisation.
Is part number 1039S80802 compatible with MINI F55 or F56 1.5 diesel?
This reference is used in selected MINI versions equipped with the B37C15A engine. However, the Bosch number and DDE designation should also be compared, as different control unit variants were used in these models.
What is required to program ECU 0281031944 for a BMW or MINI?
The safest option is to provide the original engine control unit. If it has already been read, the complete memory data can be supplied together with the vehicle information and details of the required preparation method.
