Battery Draining Mystery
Hello,
I've encountered a problem that until now no one seems to know the answer to:
The other week i went to my car and the battery was suddenly completely dead for no apparent reason. The car hasn't been standing for more than a day. MB came around and towed it. They replaced the battery with the claim that the old one was totally busted and wouldn't even hold a charge. I got the car back and for 2-3 days everything was fine when suddenly I had the same exact problem, except this time the SRS system (in charge of seatbelts and airbags) showed me an error as well. MB picked it up again but I haven't heard back yet.
Has anyone had a similar problem or could know what's wrong

They will likely hook up a DMM to the pos side of the battery in series. Then start pulling fuses. When the DMM shows a loss of amperage draw they have found the bad circuit. Then they will change parts until the bad component is found.
Hope it is under warranty.
