Hi, opcom cannot retrieve corsa d ecu security code. The tools I know are: carprog but unreliable, smok opel all but very expensive, I think also opel scanner but I cannot remember for sure. Each of these tools is 1000€ plus. Can you hold on any other module from donor car? Like instruments, radio, radio di splay? Then theoretical, you could read the eeprom of that and I can tell you security code. To read eeprom, buy cheap china upa usb.

Ok, head to bCM you should have something like programming programm immo ecu installed. Maybe post some print screens.
After that, reset airbag immo reset ipc immo. Contact out, wait 30s, contact on, program airbag immo, program ipc immo.
Contact out again, on again, head to ecu, program variant config and canbus to your car spec.

Car with spanner is just solid not flashing so I assume Immo is working and opcom is showing all Immo programmes as correct no fault codes in airbag

From now on, you need to get multimedia, otherwise I can’t help you and I will no longer reply here.

Post:
  • year of build
  • engine code
  • opcom print screen of engine ecu as you just connect to it
  • opcom with fault page showing all errors.
If you know how to measure voltage and ohms, based on the info I ask, you will fix this car, otherwise, I’m wasting my time here and I will not allow this to happen.
Up to you now!

The car was starting and running with old ecu but cut out after 10 mins I sent it to tech scan and it was unrepairable so there is no problem with car
Thank you for all your help looks like I will be sending another ecu back £200
Off eBay plus coding this is the second
Faulty ecu off eBay now

That’s unproven so far. The fact that car run and stopped in 10 min could simply mean the problem is somewhere else. The fact is known that these ecus are not repaireable so who tried to fix it might as well damaged an very good ecu. My opinion so far: you’re on wrong paths now. Good luck further.

Ok but I still think ecu is at fault IV already changed all 4 injectors, fuel rail sensor ,fuel pump ,compression is fine
Crank sensor changed ,camshaft sensor changed ,fuel pressure is all correct timing chain is all fine tecscan have 100% feedback on repairing these ECUs and give a lifetime warranty on repairs they fix 99% of ecus sent to them

Hi . I’m just new here. Just trying to work it out and you seem to know your stuff so thought I’d ask if you can help. I’m looking for a ecu pin diagram for 2011 Corsa a13dtc ?
If you could help that would be great

thanks
