hesitation under acceleration

i am experiencing a slight hesitation with my w212 E250 CGI where under throttle the car doesnt respond then after a second it suddenly starts accelerating.this happens when the car is already in motion say after a red light and i try to accelerate abit faster. what could be the issue here?
also i can hear some rattling sound when accelerating when the vehicle is changing from second to third gear.what could be the issue?no CEL light

Is your car turbo charged?

Have someone with MB Xentry (diagnostics) check for transmission software update.
