My car struggled to start and blows smoke
So I recently started having problems with my car. When I start it in the cold it turns over fine but it kinda of bogs for half a second then starts and now it’s below freezing and the car won’t completely start by itself and I need to push down the gas pedal a little bit to get it going and when it starts if shoots out thick white smoke for about 30 seconds then stops. As soon as the car warms up everything runs perfectly, idle rpm is good, temp is good, performance is good. I just cleaned the MAF sensor and the throttle body with their respective cleaners and that was the start right after, just put chevron Techron in it and waiting for that to clear out carbon deposits. Also there are no signs of a bad head gasket. Would appreciate some tips on what could be wrong, edit the car is a 2011 Mercedes c300 sport

That looks like water vapor not smoke. Normal on a cold start on a cold day.
If the car runs fine after warm up, then the closed loop is okay and the problem is in the open loop where many of the sensors are out of the circuit. What is the maintenance condition of the car? How many miles does it have on it?
