Hello!
As per Ross-Tech, to swap an injection pump you need to have the PIN code of the old ECU.
ECU if MSA15, I have the current immobilizer code, but not the old one.
If I try to log-in with the current PIN code and the old pump attached, it rejects.
Also, going to channel 50 is useless, gives ERROR.

What if I don't have the old PIN? Can I extract it from the pump or I'am totally wrong..?
