Convenience functions are temporarily unavialable
I cant tell you how much I hate this warning!!!
I bought a 2005 E55 with an insane sound system in the back-2 amps and a powercell was part of that.
I checked the battery after many of those warnings which at times would shut things down like my radio or my seats would not move. So I removed everything which is what I thought was the issue and bought a new battery.
I got a professional shop to instal a new configuration with some of the old equipment(only 1 amp and no power cell) and some new...While they were installing the stuff the battery died
They charged it up and said everything was good...Well yesterday I got another low battery signal...It had been one week since I had the new battery put in without no problems? So I charged it up and tested it. I got 12.58 sitting without ignition and 13.89 when turned on..These numbers were slightly lower than they were the night that battery was replaced but still strong.
Well today again that dam warning came on again while I was driving? I am starting to believe its the other smaller battery but my gut is telling me that the Battery Control Module might be taking a dump?
I really am tapped right now and really dont want to keep throwing cash at it without fixing the problem.
Can the alternator be messing up? I figured it was not because it shows a difference when turned on and that the battery is getting a higher voltage as opposed to being off?
Would paying the $200 to replace the front battery fix my issue?
I tried searching and found others that had a parasitic draw from seat modules and other places but I cannot find that with my car..Please help if you can

Wizos6, we have the same problems at the same time, lol. My idler pulley is making noise and the alternator regulator went 2 months ago, got a new one online and replace just the regulator without taking the alternator out. Look for one online and there reasonable.

I got the same problem I dont have a big system like you ( I want one though) but it started when I went to go pick up my cousin from the airport on X-mas and while I driving there that light popped on and my interior lights and seats/ heaters stop working and now it come on once every few days might have to take it into MB to have it checked out.
