List of products
Fitting Opel ECUs to your car
The engine control unit (ECU) manages injection, ignition and the throttle based on sensor signals. That is why a replacement is chosen by the numbers on its label: the electronics manufacturer's number and the Opel OEM number. The car model and engine size alone are not enough, because one model can come with several ECU versions.
Numbers and markings of Opel control units
Opel control unit numbers usually consist of the electronics manufacturer's number and the OEM number. Enter both in the shop search or send us a photo of the label. The Bosch number 0281001675 is sometimes written as 0 281 001 675, so search both ways. Engines in the listings here include 1.3 CDTI, 1.3 JTD, 1.7 CDTI.

Frequently asked questions
| How do I find the right engine control unit for Opel cars by part number? | Copy the numbers from the ECU label: the electronics manufacturer's number (for example Bosch) and the OEM number. Enter them in the shop search or send us a photo of the label. |
|---|---|
| What do VIRGIN and IMMO OFF mean? | VIRGIN is a control unit without the previous car's data, ready to be paired with yours. IMMO OFF is a version with the immobiliser function disabled. Availability depends on the specific ECU. |
| Is the manufacturer number the same as the OEM number? | No. They are two different numbers on one control unit: the electronics manufacturer's number (for example Bosch) and the car brand's OEM number. Both help to match the part. |
