I cannot be sure for MB cars, buts some other cars after replacing the MAP sensor you need to disconnect battery and connect back after couple minutes.
Well, as MB owner manuals say that we should not disconnect battery, at least not "red" line. So, try to unplug "black" line and plug back in and see if new MAP will be adjusted by on board computer. Seem to me, sound like that the on board computer does not know there's no new MAP installed.
Ask around for more info.
