2005 E500 wagon battery drain

... Just about to break down and have the dealer look at this one.

Both batteries brand new along with alternator. Battery will still drain overnight. Sometimes it will start and show battery low message in red. Once you drive the car for a while it will be the battery message in black. After fully charged it goes away. Park the car overnight and it will repeat.

We have pulled every fuse in the car for testing and there is still a drain on the battery. Both batteries test fine and the alternator tests fine.

Any ideas?
