I have the same thing going on except it is on all the time. When this problem first started i noticed that the keyless go and the keyless entry stopped working. If u find a solution or an answer please let me know. I have not had a chance to have it looked at.

There is a recall on the seat modules for some cars.. I know there are some people that have experienced the seat motors not turning off and draining the battery while being parked overnight.
Get to a dealer and have them run a FULL SYSTEM TEST in STAR DAS. It will go through all the modules and check for faults.
If the faults dont show up, ask them to check for the seat control module recall.. i dont know the exact name for the bulletin but it has something to do with the seats.

So the seats are supposed to make alternating noises after shutting off the car? I tried to nap in there and heard noise for about 5 mins, that eventually disappeared or I dozed off.

very easy fix. had auxillary lights wired to small battery under plastic cover on upper left side of engine compartment and battery light would come on after half hour of lights on. mbz said there is a dedicated empty plug in fuse block. have them wire it there so it taps into the central electrical system.

I'm going to guess the alternator voltage regulator, even though it was replaced under a campaign, may be faulty again. I have seen a handful of the campaign regulators fail within a year.

you can`t wire anything to the aux battery, it is only charged for a short time after starting depending on battery voltage, if drive on a long trip the battery discharges below the allowed voltage and will turn the light on
