Hello,
Hope everyone doing well. Its' been a long time and now I'm having new issue.

My battery drain overnight on a good battery and alternator.
Please advise of where can start finding where the drained are at.
I have 2004 E55 AMG with brand new battery.
Autozone confirmed it's not the battery.

Please help.
Thank you,
nphra

So it goes dead overnight? Have you inspected all lights at night?

Battery drains usually turn out to be the BCM, the CGW, or sometimes the passenger seat control module.

I had the same problem try to pull out the fuse for the seats. This works for me. If that is the problem in you tube have a video with solution of the problem
