Sooo about a week ago I get up to go to work and turn on my e53. Normally I leave it on the Sirius setting on the radio but for some reason it switched to FM when I started the car, No biggy I thought it has done this before. I go to switch it to Sirius and it completely skips that mode, goes from FM, to CD, then straight to AUX no Sirius. Weird I thought maybe I just needed to refresh my radio or restart the car? Didnt worry too much and just drove to work listening to the AUX connection instead.
After work it gets more interesting... I get into my car turn it on and the radio/nav display does not come on at all. Along with that the turn signal indicators on the dash wouldn't come on when I flicked on the turn signal, and the seat belt warning light was on even though I was buckled in. Now this is really weird so I got the car back home and plugged it into my laptop to try and see if I can run diagnostics and clear some codes (BMW Scanner v1.4.0.9). SO I run a diagnostic and the RAD, TEL, NAV, PDC, and MFL sensors dont pull up at all/no data. Now I was really worried because my car definitely has all of those.
Did a little bit of googling and people say to disconnect the battery for a certain amount of time to reset the computers as it seems the KBus is being overloaded. So I did that tried, 10 mins, 30 mins, 1 hour, and 2 hours all did nothing. Next I read something about a iPod DICE connector on the CD changer to I pulled out my CD changer, nothing plugged into it but for craps and giggles I unplugged it completely and started the car, Voila! Everything kicks on perfectly! Turn off the car and go about my day, go back about a hour later start the car, nothing comes on again...
Back to googling and some people say a ignition switch can cause various weird electrical gremlins so I tried replacing that. Still nothing. Im completely confused on whats going on and whats causing this. Anyone have ANY ideas?
