I found out my car had a small pipe that connected to the intake tube cracked just like most of the members here that have the w204 C250 either coupe or sedan. I went online and saw Flexx video about replacing the whole pipe with the tornado tuning pipe that was made of steel (I believe) with a silicon coupler so it won't be cracked again in the future. While changing out the intake pipe, I accidentally cracked the hose that I circled in the picture above. I tried to connect it again with a silicon pipe with some hose clamps but then the car threw me CEL for P0068. I assumed that because of that pipe was cracked. Does anyone here know what is that pipe called I'm looking to buy a replacement part for it. I appreciate all your help.
