i have a 2022 q50 luxe i recently purchased. about a month ago my screens completely went black and kept boot looping. the back up camera works sometimes but just shuts off every 5 seconds.when it happened it also removed the music tab from my dash. my drive mode selector still works. i took it to a mechanic and had the dcu replaced but the mechanic said it didn’t fix the issue so he refunded my money. i want to see if there is any solution before giving up and taking it to a dealership where i will be for sure over charged.
