Each time I park my Mercedes Benz w202 over night. What I  discovered next day was a flat battery the car would not start again.. I run scan on the said car no solution yet...

A scan is not going to show anything. What you have is a system not going to sleep and draining the battery. 

You need a multimeter that can measure current draw. Then pull one fuse at a time and check which system is drawing over 0.3A.

Start with the audio gateway. If not that check the rest of the circuits.
