As the title says, I am interested in knowing how this part actually works. Part nr: A272 016 01 34. I have attached two pictures, one of which inside the part. This particular part was taken off a M272 engine.
Also, how does a part like this break or becomes bad? It looks like some of the plastics inside my old part has been broken off. Thanks for any answers.
Actually I'm not sure if the part had failed. It seemed intact, but it's a piece of the PCV system on this engine, and I've seen some videos where people change this part together with the crankcase breather which lies in the back passenger side (that part had definitely seen better days)..
And since the part is easier to replace than an oil filter, I had nothing to lose

Generally, I believe if it ain't broke, don't fix it.
I recently replace the engine and transmission mounts on my 2014 C350 with 128k miles because almost everyone says the engine mounts are good for only about 100k miles. I was having no symptoms of collapsed mounts, but I changed them anyway. After changing them, the "old" mounts still had a lot of life in them, but as you said, what is there to lose? The car does seem to have better throttle response and smoother idle, but that could just be me (my wife would never be able to tell the difference). I will say the job wasn't too bad, but the first time is always a pain in the ***. I did learn that the best way to change them is to follow the procedures in the WIS, but you must follow the instructions closely since Mercedes often combines different engines and models in the same instructions. You can pull the mount out from above on the passenger side, but you need to disconnect the lower steering coupler to pull the driver side out from the bottom.
That does not mean you should not do preventative maintenance. But I usually keep to identified maintenance items (Oil and filter, transmission service, brake pads and rotors, brake fluid, spark plugs, etc.) and those that are beginning to show wear or have a problem.
You're right. Nothing to lose replacing that plastic part on a 15 year old car. Does it seem brittle?
MB has ups and downs with plastic parts suppliers.
Driving all models of last 30+ years, I can see the patterns.
W124 had excelent plastics and rubber parts. They are still in good condition even today, so if you are Junk Yard Junkee, look for them.
W210 and W163 had very fragile window regulators, grommets, hose and wires holders, so when I was visiting JY, I would pull those parts from older models, to install them on late 1990' and early 2000 models.
The breathers on OM606 engines would turn into dust with age and complicated system had to be replaced.
Our W212 passed 10 years /150k miles and the only weak part I experienced were sway bar link boots. I also replaced motor mounts, but with the mileage that was expected.
The rest seems to be solid

Thanks for your input as it shows how Mercedes-Benz improved the quality of the W212s . I really want to see this trend continues in other upcoming generations as well
