Mileage indictator keeps staying on after car is off?

I have noticed my new to me 2010 E350's mileage indicator screen randomly comes on then goes back off, and repeats this process well after the car has been shut off. I do have Keyless Go, and it does this even when the key is nowhere near the car.
Has anybody else had this problem? I'm getting concerned! I've been noticing a bunch of weird flukes with my car even though it checked out good at a private mechanic and the MB dealer in my area!
I even video it and sent to my Mercedes tech
He wanted to see the vehicle , but am to busy to bring it in for eval.
So far no it has not cause any other problem, I may just leave as is.

Watch video and u will see speedometer light up about 20 sec and then turn off for about 2 minute then the cycle start again.
I had to shorten video length so not to bore u members.

, my car is smart and it can do what it pleased
, as long as it starts when it has to
I'd be worried about battery drain ... Perhaps other electronic systems are waking up as well when that screen comes on...

And yes, I did prove this. Put the key in my room with the car off and locked, and it came on 2 times in 20 mins. Put the key at the other end of my house and it never came on.
