If you are replacing the hoses, then cut them off if they won't slip off. I replaced all the rubber vacuum hoses on the C240 and had no issues with anything in the way that couldn't be gently moved aside. But as I said - I replaced all parts so I wasn't worried about damaging adjacent hoses.

For me the easiest way to replace those hoses was to remove MAF sensor first (
- I didn't remove hose from MAF sensor while removing MAF sensor). After removing the sensor you'll be able to remove the rest of the hoses as one piece (see attached photo).

The yellow X is on the engine wiring harness. It's held down with zip ties. You can cut some of those and move it out of the way enough to get to the hose.

Yeah, that hose on the MAF sensor housing/elbow is a pain.
