Hi.
Your Opcom PCB looks like a good "Opcom New". D5 and C22 are not visible. It has a real PIC 18F458 at 99%. However, the risk is there.
If you don't take the risk, you won't know. I changed my FW cable from 1.67 to Chinese 1.70 and it works with Fantomel's software.
Unfortunately, I couldn't check on the car because I don't have any Opel.

Take pictures of both sides of the interface PCB and post it here. Maybe it has a fake PIC 18F458.

the links don't work?
I can't download any software.
I have an interface that appears to be a good opcom. with the software they gave me, it gives me "interface communication error or interface not powered from car". how can i solve

Fantomel's last link with SW still works. (YANDEX yandi)

Thank you. maybe I had skipped it. i tried the software but it doesn't connect. searches for the interface and stays there for hours, as in the picture

Follow all the steps from Fantomels' post and it will work. You have a driver issue. Use CMD uninstall to clear that Vauxcom driver installed earlier, reinstall Fantomel's software and will work ok.
