BMW F10 (F07) No Crank No start! No communication with ECU (DMA)

Hi all !! When I hooked my scanner to diagnose no crank no start issue of this bmw 5 series f10 (f07), I did not have communication with ECU ( DMA) of the car! I’ve thought it might be the ECU and need to be replaced! The thing is that always need to check the fuses first before attempt to leave the car to the dealer! In this case if one of these fuses blows up, you have spare ones do not buy complete distribution box because if one fuse!
