Opel Engine Control Units – ECU for Astra, Corsa, Zafira and Vectra
Opel Engine Control Units: Choosing by Part Number
At Auto24Parts you will find used original engine control units for Opel cars, including the Corsa, Astra, Vectra, Zafira and Meriva models, inspected and tested before sale. Refurbished control units, including Virgin versions, are also available. 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 55557933AX or 16188269NC, 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, Virgin or full set. We describe them on the ECU preparation options page.

Opel Engine Control Units: ECU, ECM and Engine Computer
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. 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 an Opel 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 Opel (GM) part number, for example 55557933AX, 16188269NC or 90562575LM,
- the control unit manufacturer's number, for example Bosch 0 261 208 940, Delco, Siemens 5WK, Delphi or Magneti Marelli,
- the full designation, including the final letters,
- the engine code and the designations from the listing, for example Z13DTH, X14XE or A16XER.
A similar housing and identical connectors do not confirm that two control units are compatible.

Refurbished and Virgin control units
Some listings describe the control unit as refurbished and others as Virgin, meaning cleared of data from the previous vehicle and prepared for reprogramming. Examples are:
- refurbished Opel Corsa D 1.3 CDTI control unit, number 55198931CJ,
- refurbished Virgin Opel Corsa D 1.3 CDTI control unit, number 55566039HK,
- refurbished Virgin Opel Corsa D 1.3 CDTI control unit, number 55573953QU.
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.
