The EPS shows part 20 as the pressure sensor, which is close to part 2 in your picture. This is for my 2013 C250 but I would think this is similar for your 2012 C250. I'm fairly sure that part 1 in your picture is part of the intake hose, 2710902029, and cannot be purchased separately.

The dealer asked for 130 dollars. I found the one I sent you on amazon but do not know whether the map or the one by the throttle. Is #9 on the image the MAP sensor? If so what is the name of the one by the throttle
The car has an overboost code and making an annoying noise. It seems like the car is going on low gear until I press on gas to make it stop.
I also noticed when I shift to six gear manually and remove the foot off the gas, the noise is less.
I was reading about it and indication goes towards one of those two sensors and or the wastegate..therefore I am going to replace one sensor at a time
