I have a problem with my id on vag simos pcr 2.1 with foxflash software on bench. 12.3v battery and connections ok it doesn’t make me ID, what could it be?
Check PIN out if ok the problem is the voltage. For pcr2.1 needs minimum 13v. V13.5 is recommended.
Change power supply and try again.
In fact, the voltage has risen and it went well.
