I did this to the project 2000 S500 a bit over a month ago. I found it easier to just remove the entire air intake.
1.) There's what looks like a quite large, circular clip at the top. Use a screwdriver to gently pry its lever open and remove that clip.
2.) Remove the electrical connector for the MAF. It's a clip-on like other M-B connectors; mine came off with minor persuasion.
3.) There's one clip in the back of the air intake that I could see. I undid that and then just kinda gradually twisted the MAF out. There is what looks like a second clip below that, but as I recall, it's more like a plastic spacer "stud" more than anything else. Anyway, it does come out with some gentle-ish persuasion.
You should now have the room to manoeuver the EGR pipe so that it'll come out.
