Hey guys, I’m gonna tackle this problem over the weekend since I just got a P0400 fault today so I’m gonna clean the egr valve and plumbing. I wanted to make sure I’m looking at the right thing since this is the first time I’ve had to do anything under the hood with a Mercedes. Any help is appreciated and I looked at threads already but didn’t find pictures of my engine and year specifically.
