Somewhere in W163 archives you will find a topic where young MB owner used his friend for oil change.
His original question why after motor oil change, the transmission would not pull.
Long story short- his friend drained transmission and filled additional 8l of motor oil.
So with 16 l of motor oil - the engine still run with no symptoms. Obviously it was not driven this way.

Dipstick O-Ring is available from the dealer
Part Number 022-997-75-45-64 (O-RING)
Not sure why people here are buying whole new dipsticks bruh
If it does not fix your problem, it is most likely the breather valve thing.

I had a 1992 Volvo turbo wagon, the old cast iron 4 cyl RWD variety, that had about 260,000 miles, and when heavily loaded on long grade ascents (say, eastbound I80 from Sacramento over the high Sierra), it would blow the dip stick out if I stayed too hard on the boost too long.... it was a clogged up PCV system combined with excess cylinder ring blowby and/or valve stem seal leaks, aggravated by the sustained turbo boost. I just backed off a little and stayed at the 65 MPH speed limit under those conditions and didn't have any issues.
as someone said above, Mercedes has been quite into complex labyrinth PCV systems involving oil recapture, typically molded into the inside top of the valve covers... if the car has been run long and hard on old oil, those can get pretty gummed up. now, I'm not positive what they are putting in these newer engines, last engines I was really familiar with inside and out are the M103 and M104 inline 6's of the early/mid 90s.
edit: oh wow, the M276 3.5L V6 has a oil centrifuge in the vent path, hah hah. looks like there's hoses from both valve covers (drawing is vague) to a centrifuge case, presumably driven by the timing chain or something? parts diagram is pretty unclear, but it appears to be buried in the central V of the engine between the intake manifolds

The O-ring was not previously available. I had checked with several dealership part dept. and was told you have have to buy a new dipstick. Thanks for the info.

Unfortunately some dealers parts persons don't know how to look up these parts. Someone like Konigstiger here on the site is a great asset to have in your corner when looking for things like this. He is very helpful and willing to contribute part numbers and even pdf's for repair info...

The o-ring that you are referring to seems like it's for another 3.5L dipstick.
A remarkable difference between my old o-ring and the new one. The old o-ring was swollen with a circumferential flat spot where it made contact with tube. Problem resolved with the new stick.

So help me understand, do we have a new dipstick design (new part number) with replaceable o-ring or we could still use the o-ring mentioned above on our old dipstick?

For your vehicle (non-4matic) replacement diptstick is 2760100572, o-ring only 0229977545. 2760101872 (also utilizes o-ring 0229977545) is for 212 4matic vehicles only.

My 2012 E350's oil dipstick keeps popping up, first, it was doing every couple of weeks, now it has become almost every few days. Back in August of this year when my CPO was expiring, the dealership said they replaced the motor and transmission mounts, and they said it should take care of the problem. The problem is still there and has become more frequent in the last few weeks. Anyone experienced, the same problem with their W212? Mine only has little for 52K miles. I am no longer under warranty, any ideas where should I begin troubleshooting this problem? Thanks

No lemon laws are going to extend to a car that is 9 years old. He might can get the dealer to goodwill a repair because they said it was fixed, but if its been more than a year since then he may be SOL.

According to the EPC, the 276-010-18-72 dipstick does not list an available o-ring.
The o-ring that you are referring to seems like it's for another 3.5L dipstick.

Save yourself $30 and buy the o-ring instead of the stick . Doooh!

Same on our '11 E350 4M wagon, the dipstick would just pop out slightly and the o-ring was flattened and hard... I ended up using P/N: A 006 997 26 45 or A 019 997 76 45 (12x2 mm). It seemed to be the right size (at least for model with M272) and I had a bunch as it was a common size on older platforms.

This happened to my wifes 14 E350 today. could hear gurgling from the dipstick tube took me a while to notice with the car running where the noise was coming from!!
Im sure oil level is fine and oil was changed ages ago.
I'll replace the O ring people are talking about but what PCV items should also be checked? Anybody got any pics or partnumbers??

FWIW, I've only experienced dipsticks blowing out on high mileage turbocharged cars after extended high throttle and high boost, like climbing the Sierra on eastbpimd I80 at 80MPH plus on a hot day with a full load in my old 1992 Volvo 740 Turbo wagon that had 265000 miles of throttle mashing.

It sounds like its semi-normal on these and is just the o ring getting old or to much oil around the top of the dipstick tube from an oil check or splash from pumping the oil out of there during an oil change.
Atleast I hope it is. Mine is tuned but only just did that and its just being putted around town until I drive it once in a blue moon.
I am wondering about PCV though because I need to do the magnet o rings on the front of the heads too they are leaking too. This cars only done less than 70k kms. But as said its just putting around town so rarely sees high rpm until I drive it which was yesterday which explains why we noticed the dipstick popped this morning. I deff gave it a pull yesterday.
Think I'll just put a cable tie on the dipstick tying it down for now until this o ring turns up as got to go out of town in it this week.

the same thing that pops the dipstick will greatly accelerate the oil coming out the cam actuator/sensors and soaking into the harness

You have a low mileage (70,000Km... 50KMi) car gently driven around town that just wants to pop its dipstick.
Low RPM around town is linked to low oil pressure with disabled piston spray coolers below 3500RPM - I wonder if this indeed jams the piston rings with burnt oil deposits, causing this HIGH BLOW-BY
The work around may be to re-enable the normal piston cooling sprays by disabling the pump low-pressure solenoid.
One headache purposely made to save pennies.... that what TT V8 owners were after to save our planet!!
