Oil fill experiment
The Bentley manuals says the 2010 e60 takes 6.9 US quarts of oil in the crankcase.
When I change the oil I always put in 6.9 quarts.
I ran an experiment today when I changed the oil. I only put in 5.5 US quarts of oil.
I then got into the iDrive and it registered all the way at the Max mark.
That leads me to believe when the oil is drained, it doesn't all come out and I've been over filling it for years.
Alternatively, my oil gauge in the bottom of the pan could be inaccurate.
If I have been over filling it for the last 3 years, maybe that is why the oil pan gasket leaks today?
Maybe the rear main seal and the front main seal are also compromised due to the excess pressure?

How much oil did you drain? I doubt that you have been overfilling by 2.5 qts every time.

Yes, I did measure the oil precisely when it drained. There were 7 quarts that drained out of the crankcase. However, when I put 5.5 quarts back in, the oil pan sensor shows MAX in the iDrive screen.
Now the question is:
- when the oil pan sensor is malfunctioning, does it get stuck on Max and always shows a Max reading?
- when the oil pan sensor breaks, does the iDrive screen go black with no reading at all?
- what are the characteristics of a broken oil pan sensor or malfunctioning sensor?
There is something interesting going on. Below are two pictures of the iDrive screen oil reading. At the top of one screen, I show how a portion of the measurement has been cut off now that I only put 5.5 quarts in the engine.

It took 2 days for the oil sensor gauge in the oil pan to produce an accurate reading for 5.5 quarts in the crankcase verses 6.7 quarts.
Today I got in the car and the iDrive screen said, 'the oil level is below the minimum. Do not drive the vehicle'.
Just as an experiment I tried to get the oil measurement screen to see how low it was actually reading at 5.5 quarts. The iDrive would not produce that screen.
I added one quart of oil and I was able to get the iDrive screen showing the max oil level in the car.
