Strange battery drain
Hello all
I'm pretty new here and this is my first mercedes. I've owned it since last spring and it's been a blast, but over the last month the battery is dead if i go 3 or 4 days w/o driving the car (brand new battery)
I've been reading on here that the usual culprit is the seat controller, so I unplugged that, and it hasn't helped.
I unplugged the wires under the passenger seat. Should I pull the door panel and unplug the switches as well?
Is there anything else that commonly causes a battery drain?
..oh, and I inadvertently unplugged the airbag wire under the seat so the SRS light is on (the yellow 2 wire one). I plugged it back in but the SRS light stays on, is there anything I can do about it short of going to the dealer and dumping out the contents of my wallet?

Pulling fuses is a common procedure. Pull several and check the draw until the circuit has been isolated. After the circuit has been determined, start unplugging components on the circuit.
The SRS code can usually be cleared with a code reader.

I had the exact problem with my passenger seat. I unplugged all the wires to the controller box for the seat except for the yellow and red plugs which solved the problem with the battery dying out but obviously the seat is not going to move in any direction thereafter so if this is OK with you adjust the seat to where you want it for comfort and then unplug the wires/plugs. As for the warning light on your dash, you'll need a diagnostic scanner to reset the code which plugs in under the drivers side of the dash. Hope this helps.
