Xhorse Multi-Prog Clone Audi BCM2 Data Guide

Problem:
When using Xhorse Multi-Prog with an old BCM2 adapter to clone an Audi BCM2 (A4 type), the module shows as encrypted. Synch data is not required, and you can read Data 1 and Data 2, but don’t know how to use these files.

XhorseVVDI.com Engineer’s Solution:
The old adapter cannot complete a full read, so full cloning isn’t possible directly. You need the new BCM2 adapter or process the data manually.

Steps:

1. Read Data 1 and Data 2 with Multi Prog
2. Load both files into VVDI Key Tool Plus
3. The tool will generate:
   • Service File
   • Key (IMMO) File
4. Write the Service File into the donor BCM2

Result:
No synch needed — BCM2 cloning completed successfully.
