Throttle body cleaning

[suthernfaries]

I’ve been told my throttle body needs cleaning, however I can’t seem to locate it.
I’ve got a 2011 c220cdi.
Am I right in thinking this is at the back of the engine in the middle ?

Lovely cheers mate, you reckon it’s easy enough to do or better of sending to a garage ?

Who told you and why?

3 fault codes to do with the throttle. Mercedes specialist said he’s 99% sure that’s what the problem is,
Throttle feels sort of lumpy, not smooth n like it’s being blocked

Merc specialist with a solus diagnostics?? If I were removing the throttle to clean, I would be replacing it as it’s a pain to get to.
