How to use Xhorse Multi-Prog Programmer to read Audi BCM2 Module without soldering?
We need to use Xhorse Audi BCM2 Solder-Free Adapter to work with Multi Prog to read BCM2 all data, and use VVDI2 Key Programmer to calculate BCM2 immo data and save service file, and then write the service file back to BCM2 module with Multi-Prog.
In detail…
1. Read BCM DATA1 with Multi Prog
Connect Multi-Prog Programmer and a computer via USB cable
Open Multi-Prog software
Select Device>> BCM2>> LOCK_BCM2-2 (ADAPTER) (AUDI->AUDI) >> OK >> Detail >> General info/ Connection diagram
