Hi Crew!
My 2005 S430 is doing this thing where it randomly kills the battery, just to the point of not being able to start.
Its like every 3-4 months this happens. I have to pull the passenger floor, hook up the cables to the wife's Suburban and jump my Benz.
The voltage at that point is about 11 volts.
One random note, recently when I turn the car on, sometimes the wipers make one pass the park themselves.....
So here is more info:
Ive read on here to shut off the command before you shut the car to prevent this. So after the last time, 5 months ago, I started shutting the command before I shut the car.
Fast forward to last night. The car is dead. I jump it. It starts. I drive around for a while and it recharges.
I park, i shut the car off, and locked the doors, but stayed in the car for about 20 mins.
The car makes a gremlin noise, a real quick one (after all the normal gremlin noises), the command comes on, and then shuts. it does this over and over.
Today I pulled the fuse for the command (fuse 22 on driver side, I think) in the hopes that this kills whatever is triggering the 'gremlin' to keep going on.
I ran some scans and this is what I found. (see pics below)
These codes dont seem to be related to the command doing its funny thing.

Try removing the disc from the COMAND slot - sometimes, COMAND gets confused and keeps checking the disc, and never lets the car shut down completely.
You are leaving the wiper switch in the first click on, which is the AUTO position. Both of my S-Class cars have done the same random one-wipe upon starting the engine. It's never been irritating enough for me to make a research project out of it.
It is possible that one or more of the reported shorts to ground could be causing a problem.
"CURRENT" means that there is a short at the time of testing. "STORED" means that there was a short at some time in the past, but it isn't there at the time of testing. The usual way of running the "Quick Test" is to run the test, write down the trouble codes, clear all codes, drive the car and run the test again. The system stores everything until it is cleared. If you clear the codes, then run the test again and get a "STORED" code again, you will know that there is an intermittent problem.
