Sorry to hear that for you. From my discussions with some of eMMC 3rd party fixers over the last couple of years, I have learned from them, that all the different functions such as WiFi, BT, Radio, Music streaming even the "apps" that bring up the display are Services. And one of the symptoms of a failing eMMC is the code/files for those Services is corrupt or can't be read from the eMMC in order to execute. I not read backwards in this tread looking at all your previous posts, to confirm yes or no, that your eMMC has been replaced. But from what you just described about your WiFi and BT, it sounds as though, no, your eMMC has not been replaced. I hope for you that I am mistaken about my read on what's going on with your car, but just putting out there for you from why I have learned. And from my experience on TMC, someone is going to point out to me that I am completely wrong.
