Hello,
I have a Lexia cable, Diagbox 7 and a car that I no longer have the pin code for a new key as the BSI/ECU was replaced by a donor several years ago.

I've read you can dump the ECU or BSI to retrieve the pin code but unsure how people are doing this? Any tips? Do I need a different cable to do it?

I think it is a siemens ECU

Thanks,

Robbie
