During the winter season, many BMW and MINI vehicles suffer from flat batteries. After a jump-start, customers often report issues like windows not working or other electrical functions failing.
This is usually caused by the FRM3 module corrupting its software during a low-voltage event. When the EEPROM data shifts into the D-Flash area, communication with the module is lost, and dealers often recommend replacing it—an expensive solution.
Xhorse Multi-Prog: A Better Fix
Instead of replacing the FRM3, you can open the module, connect directly to the board, and restore the software. This realigns the EEPROM and brings the module back to life.
The Xhorse Multi Prog makes this process even easier:
- Automatically detects and repairs corrupted FRM3 partitions
- No manual editing required
- Reads and writes reliably
Supports soldering or clip connection (no soldering needed)
VVDI Prog vs. Multi Prog
VVDI Prog can read and write FRM3 data, but it cannot fix the corrupted partition automatically.
Multi Prog performs the repair for you, saving time and reducing errors.
For fast, safe, and cost-effective FRM3 repair, Xhorse Multi Prog is one of the best tools available in 2025. It restores communication and function without replacing the module, making it a must-have for BMW/MINI workshops.
