Replaced battery & alternator; all lights still showing-RAS, SOS, ESP, SOS, etc. on 2002 Mercedes-Benz C240

Please tell me what can be done, or is it time to get rid of it. Also, it won't change gears when pulling off, added trans fluid about 2 wks. ago, when all of this started. Alternator & battery replaced in the last 48 hrs., but still getting the same error displays: ESP, battery/alternator, SOS, SRS, and more that I can't even remember. It's traumatic to stop in the middle of the street...

You need to take it to a qualified M/B tech.
