A customer tried to install a used Audi radio unit from eBay, only to be hit with the dreaded Component Protection (CP). Like many, he believed it would be plug-and-play—but reality had other plans. After unsuccessful attempts with various CG programmers and efforts to manually transfer EEPROM data, the solution finally came from Xhorse Multi-Prog Programmer.
While CG100 and CG Pro 9S12 failed to read the 24C256 EEPROM, the VVDI Multi Prog stepped in and read the chip effortlessly—saving the day!
Why It Worked:
- Powerful chip recognition for 24C256 EEPROM
- Stable read/write operation even when others failed
- Reliable support for EEPROM/FLASH operations in component protection repair
Lesson Learned:
Not all programmers handle every task flawlessly. Having multiple tools—and knowing which one works best for specific jobs—can save time and avoid costly mistakes.
If you’re working with Audi radio modules or dealing with CP issues, Xhorse Multi Prog deserves a spot on your bench. VH13 Adapter is required.
