Hello everyone,
I'm currently sitting in my girlfriend's 1989 Volkswagen Golf and I'm at my wit's end... We gave the car a new engine: an AFN from a 1998 Seat Ibiza 6K.
Unfortunately, the immobilizer control unit went missing during the renovation phase. We quickly bought a new one. However, I haven't been able to program it.
I have also searched this forum and others, but I haven't found any instructions on how to reset the immobilizer.
VAG Com version 311 is available and licensed/activated. I would like to update to a newer version; is there a guide for this? I only borrowed the VAG Com, so it would be great if I could also explain to the friend how to perform an update

.
Here is some device information:
