Where is the throttle body and sensor on a w204

[Mymercedes220]

Still having this eml throttle issue. I replaced the pedal and the light is still on.
Perhaps it's the throttle body it's self?

Where abouts is it on the c class 2011 220cdi estate ?

Maybe I can clean it up or so . Worth checking, can anyone advise ?

Thanks all
