  • [Corsa C 2000-2006] Opel Corsa C 1.2 16V ECU location

    Hello. Hope this is the right category. Here is my situation. The car has suffered a pretty bad accident, so many parts had to be fixed/replaced. Once that was done, the car won't start. The service light stays on all the time.

    We had someone plug it into a computer and it showed an immobiliser error. After little investigation, I found that the immobiliser is located inside the ECU.

    Can anyone advice where exactly is the ECU located, and possibly what should be done to reset or whatever to fix it?

    Thanks in advance!

    Towards the back on the right hand side as you look in the engine bay. Check it is earthed as that is a common issue. Resetting usually means using diagnostic kit. Other than that you may need to send it away to an ecu specialist, or buy a replacement ecu with matching transponder and key chips.
