Sounds like the MOST bus system has gone down, if the CCC (car communication computer) hasn't already failed then it is probably on its way out, you need to find someone who knows the system well like a BMW dealer. Oh a quick check to do is hold both ejects button on the CCC front panel and at the same time press the on/off button, this should reset the CCC and may jump it back into life?

WENT TO BMW DEALER...SOMEHOW WATER GOT INTO THE TRUNK..SHORTED OUT THE CCC, UNDER THE CARPET!!...3500.00 IN PARTS ALONE...WANTS TO WATER TEST THE CAR TO FIND THE LEAK...UGGGGGGG

Water issue is your problem. Hardware will need to be replaced.
