Fixed! VVDI Audi 754J Remote Generate 868MHz OK but Stay at 433MHz

---

Question:
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.



Answer:
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
