A little update, a friend of Highline-Autos stopped by our Cars and Coffee last Saturday, he let me know he had used his Fidelity warranty we sold him to fix his RMS, saved over $10K at the local Scottsdale Mercedes-Benz dealer!

Holy hell that's a lot of blow-by for only 1000km.
Do you guys make a lot of short trips & not let the oil temps get above 200f? Water does boil at 212f. I would think idling the motor for a few minutes above 210f would take care of the water & condensation from the blow-by and keep the motor from blowing through the RMS by keeping the engine sludge under control
None of the above scenarios apply to this car. Work is 30 km away. Also the system was installed right after break in period and have been going at it pretty good. Temps always out of the blue font of death for both oil and trans. And yes temps go up 97 C on the regular . The fact is if RMS’s are blowing its not likely the driver habit thats a problem. The new aftermarket versions will have an empty schedule of 3000 miles or 5000 kilometers which is more in line with what an oil change interval should be for engines like these and the way to empty it is pretty trick! Expect to pull out about 500mL total at that point! Each can is now able to collect a cup’s worth of volume each!
edit: bank 1 had condensation (weird) and bank 2 had none. Again new engine driven normally with the occasional full load on the throttle. I definitely try to stay out of 4 cyl mode where possible! Last! Installing the new production versions in about a week’s time and I believe the three testers will be receiving the same treatment around the same time! I would allow the warranty to carry over but I am in love with this car too much to let it suffer or get to that point where a failure could be prevented

The only reason oil consumption is a misnomer is because of how these manufacturers routed the “blowby” system. Essentially the crank and heads are subject to a constant vacuum from the intake manifold which means you are recirculating oil vapours constantly. Some oil are burnt, some turn to carbon deposit in DI, but most are trapped in the intercoolers and intake plumbing. M177 engines will always be subject to AOS failures with the way they operate from OEM.
The life cycle of this engine suggests most will go past the warranty period which would place it in a recall category if enough owners push MB-AMG into a class action lawsuit type of scenario. The last time this happened was with the M156 valvetrain and MB won.
Burning oil isnt accurate. Also the M177 systems are not available to purchase, so no one would be able to pull the trigger on this product until it is released 😅. But were getting amped up for the upcoming release date M177 PCV
Thank you for the details, really appreciate the explanations. Still interested! I just know me and I would forget to empty the things. Enjoying watching the progress and revisions. Thank you I don’t mean to be a party pooper. With the RMS solved there’s not a lot more that goes wrong compared to the M157 which as many “quirks” so this solution is very exciting….
The PCV principle of operation on M17x is the same as the latest generation of Porsche vee engines, the EA825 4.0TTV8 and EA839 3.0T/2.9TTV6. Lots of crankcase vacuum which reduces the net emission effect of blowby.
Major design flaws in modern German engine PCV systems are cheap plastic components (tubes, diaphragms, etc.) and the routing of vapors in a way that permits condensation in the tubing.
Is there any kind of a common thread here for failure? I have 33K on my 2019 S63 and I love the car but feel like I am driving around carrying a hand grenade. It is garage parked every night and not really exposed to any extreme temps here in the PNW. I typically drive it for extended periods of time but it is also my daily driver. Want the kit when it becomes available but hope it is a DIY thing as I do most of my own wrenching. Are there any sensors that offer crankcase pressure data?
There are two W213 threads on RMS/oil vapor separator failure. I think also a W205 and a W463 thread in each section. So, no, there is not one consolidated thread for this.
They gave me a simple one-line, hand-written estimate, and I didn't ask too many questions. But based on the number, I'm sure it's just the seal and does not include the separators.
Either way I'm not too concerned, as I'm putting the car on the market shortly.
Now I will never know the outcome: I drove my wagon for the last time today, it's sold. Sad, but with the RMS issue costing significant dollars to repair, only to have it recur in another 50K (or so) kilometers, I felt it was time to say goodbye.

Did you sell it to the dealer? Pay to fix it then sell it to someone else? Did you not fix it and sell it to someone else?
Did not fix, sold to a re-seller. Definitely got less than I would have with a private sale, but the transaction with the re-seller was basically painless.

If you did not sign any docs disclosing any unrepaired issues, then you are ok. Some dealers out there will ask you to sign the mentioned and may come after you if they later discovered you have knowingly failed to disclose the fact (pre-existing issue).
Of course, the reseller knew the potential risks every time when they buy used vehicles.

My question is, looks like this is a MAJOR issue for w213, WHY IN THE WORLD didn't MB recall for this issue?? This seems like it's a super common issue and in my car group, everyone and I mean everyone who had a w213 E63s has had a RMS failure.
The reservoir has also been increased. The increase, plus with the easy drain makes the usability to be more in line with what owners expect. The videos above had the reservoirs filled with fresh oil for demonstration purposes. With that, the kit is now in production and available online. Keep driving your cars!

so does this fix the separators clogging up some how?
Just chiming in since my 2018 E63 AMG-s has now had the dreaded RMS leak at about 55k miles. I took her in for the transmission service after the spark plug service and they found oil.
Now for the good news, my Veritas warranty is fully covering the RMS leak as well as replacing the oil vapor separators!!!
Car has been in the shop for about 2 n half weeks waiting on parts which just arrived today.
Let this be another cautionary lesson for anyone considering an E63 AMG-s, buy the extended warranty or be prepared to drop 8-10k on a RMS leak repair.
I will say that I started using launch control and launching the car often in the months prior to the RMS leak being detected, coincidence? Possibly.
All that being said, still top 2 sedan you could ever buy and it’s not #2!!!
