OM642 manifold absolute pressure sensor

Could someone please indicate the location of the map sensor on the OM642 engine in the 2011 CLS350CDi?

Thank you.

On my previous E320 CDI, I believe it is located on or adjacent to the right-hand air filter box when viewed from the front of the vehicle.

Upon examining some of my old engine photographs, it appears that the issue may be located in the middle of the right-hand manifold, a few inches to the right of the fuel filter when viewed from the front of the engine.

I now believe I am mistaken on both counts.

You are correct; that is indeed where mine is located.

[SushySosa]

Thank you. Is it challenging to access?

[AmericaMonster]

Incorrect...directly atop the engine.

Excellent, thank you. I will remove it to ascertain if it is obstructed.
