I bought Xhorse XSADJ1GL VVDI Universal Smart Remote Key for Audi (Immo5, BCM2 system) I can’t prepare 868 MHz. 315 and 433 MHz prepared ok. But when I try to create 868Mhz I get key with 433 MHz. but work good after programming. I tried with my Mini Key Tool.
Here Xhorsevvdi tech
1.VVDI Mini may not identify the frequency of 868MHz due to its weak signal
2.Program the new 754J Remote after successful remote generation
