I have a 2003 E55 that's experiencing some electrical issues. Here's a list of issues it's having:

-Dashboard lights completely off. The lights for the orange needles are on, though.
-Dashboard clock doesn't work. Everything else does
-ESP malfunction light comes on.
-Alarm randomly turns on, even while driving.
-Cassette door doesn't open and the screen is always stuck on "close door" and I can't change the radio or anything, even the CD changer won't open when I press the button.


So, what can be causing all of these issues? Both the main and aux battery are brand new. I replaced the alternator with a new Bosch alternator less than 2 years ago. Any help is appreciated!
