Here is what happened, I fixed my EGR valve problem, cleaned off the tube, the valve itself and put everything back in place, but I notice that there was a vacuum line hanging that runs from the RT side from the fender (Opposite where the Fuse box is) and that has more vacuum lines & connector going into the car. Now my A/C Center Vent stopped working, i got it stuck at windshield and side vents. I have read that a cause is a vacuum line that came loose, which I think is the one that runs across the firewall back of the engine which is the one I'm talking about. So what I need to do is to locate the connection to where to connect the vacuum line that is hanging, to which my knowledge I've read & I heard is the cause of why the A/C Climate Control center vents do not work. Since my C43 AMG is vacuum pumped unlike the C230 Dial knobs, I cant rel on my C230. So if any of you have pictures of the back where is connects to, I would be gratly appreciated. The reason I ask is cause I checked my C230K and i don't think it has the same vacuum lines coming and going as the C43 Automatic Climate Control air control system. So Please kindly sirs that can take me a pic that would help greatly.

It plugs in by the throttle. If you remove the air box you should be able to find it pretty easily

Thank you man. I fixed it. I connected the lines incorrectly so now I double checked and now I can say its good now. Much appreciated. That was the vacuum line that connected to the left of the throttle (right side when facing the car)
