    First, you should check if any interior light stays on.

    I had the same problem. It took them a month to find out that the radio was draining the battery pulling about 5V even when the car was turned off. They also told me that I had to replace the key, because it had no functions. I told them that I read on MB World that it could be the ignition. So check that before I replace a $300.00 key. "No that's not the problem" Needless to say after replacing the key the ignition had to be replaced also. Have your tech check all aspects. They're probably guessing as well.
