BMW DDE & DME Engine Control Units – Bosch, Siemens and Continental
BMW Engine Control Units: Choosing by Part Number
At Auto24Parts you will find used original engine control units for BMW cars, including models designated E34, E46, E60, E87 and E90, inspected and tested before sale. Control units for other makes and models can be found among all engine control units.
What matters when choosing is the complete part number from the label, for example 7794218 or 0281011224, not just the model and year. If you are not sure, send us a photo of the label on the original control unit and we will help you check compatibility.
Engine control units may be offered in several preparation variants, for example locked, unlocked or full set. We describe them on the ECU preparation options page.
List of products
BMW Engine Control Units: ECU, ECM, DME and DDE
An engine control unit, also called an ECU, ECM or engine computer, is an electronic module that manages engine operation based on signals from sensors. In BMW listings you will also come across the designations DME and DDE. When it fails, the car may not start, the engine warning light may come on and the diagnostic tester may be unable to connect to the control unit.
How to choose a control unit for a BMW by part number
Model, year and engine capacity are often not enough, because the same model can come with different versions of the control unit. Before buying, compare:
- the BMW part number, for example 7794218, 8589145 or 7541459,
- the control unit manufacturer's number, for example 0281011224, 0261209005 or 5WK93643,
- the DME or DDE designation given in the listing, for example DDE8596362 or DME 7519592,
- the full designation, including the trailing letters and digits.
A similar housing and identical connectors do not confirm that two control units are compatible.

Older BMW modules
The older listings include, among others:
Our range changes regularly and not every listing states the year and the engine, so compatibility is determined by the number on the original control unit.
Engine control unit variants
Engine control units may be offered in several variants: locked (with data from the previous vehicle), unlocked (for example Virgin, with a PIN code or CAR PASS, IMMO OFF or Plug and Play) or as a full set. Whether a unit can be prepared depends on the full part number, the manufacturer and the immobiliser system. We describe the details on the ECU preparation options page.
Used original control unit: condition and inspection
We sell used original control units, not new parts. Every unit is inspected before sale, and you can compare the numbers in the listing with the label on your own control unit.
