does unplug the battery and wait for like ten minues help to reset the computer (including like transmission computer....radio code .... etc) on w203?

 

Unplugging the battery will erase some of the data in the ECU (such as your adaptive driving), but will not reset the computer completely. I was told some info needs to be reset by the SDS. Our radio doesnt have radio codes. I am not sure how long you are supposed to unplug it, but just to make sure, leave it overnight.
