Hi all,
I used my OBD scanner and got Fault code P0346 (Camshaft position sensor Bank 2 Sensor A). I read through the threads and watched countless videos on YouTube of W204 owners replacing their camshaft sensor). My vehicle is a 2014 C350 4Matic
Im aware that Bank 2 is driver side , but for the life of me I can't find the Camshaft sensor! All the videos and pictures of W204 engines I saw online don't look exactly like mine (so couldn't follow the steps). I took a picture of my engine (attached). I circled in red what I suspect to be the camshaft sensor Bank 2... Did I guess correctly? If not, where is it hidden?
And if i.did.guess correctly, how do I take it out? Looks impossible to get to!Thanks Picture of 2014 Mercedes C350 4Matic engine

Yes, you got it !
To access remove the chunky plastic intake.
Check for signs of "oil in harness" while inspecting
It's the kind of busy job you don't want to do too often for free...
the way to go is combine that with other items that require the same steps, like:
Bank1 sensor + 4x actuators
chain tensioners
PCV diaphragm
Spark plugs + boots

Thank you CaliBenz ! Yes that sounds like a busy busy job on this engine model. Seems to be much much easier on other engines
Just posting another data points for future thread searchers (hope it helps)
The engine model is M276 (will make your future online searches easier)
I found this excellent video - guy is replacing sparkplug's and ignition coil, but shows step by step how to remove the intake manifold and all hoses and wirings that are connected... quality of video and super!
I am also attaching the service manual for engines M 276 and 278 so you know where the parts lay in diagrams
Conclusion - this is a busy job and need someone who knows what they are doing on this specific engine model due to its layout (i'm not a seasoned DIY to carry this out solo without screwing things up). I'm going to a licensed Benz mechanic!

“Busy” is putting it kindly. It’s a 10 minute job on my M271. The M276 engine is quite reliable, but what should be minor repairs are made extreme by the packaging.
BTW — There are a couple of threads where the spark plugs were changed without removing the intake manifold. But it takes extreme patience, contortionist skills, and flex joint tools.
