I can’t say if there is a technical protocol into replacing separators as well on rms leaks. My case was based on verbal consultation between dealer and Germany. Besides, i want them replaced no matter what they say since i’m paying the whole repair anyway. I just dont want this crazy nonsense anymore.
i know the separators parts themselves are only a few hundreds $ … maybe you can consider paying that on your own … if feasible ??

I was just thinking that, paying it on my own at an indepent shop. I'm going to talk to the Chevy dealer tomorrow and see if they will do it based on what I've read, maybe they'll take a look at them, and consider how much extra work it would be to change them
I got a video from the service manager today, theyve got the front of the car apart, wheels off, looks like the front axles/cv joints out, driveshaft out, tranmission still in. I asked for photos because the video he sent me is poor picture quality, but he never got back to me.... Im not sure how to upload a video to here. Im going to talk to them tomorrow, I didnt think the front of the car would have to be taken apart, but my guess is it does for the upper main seal of the oil pan?
Update: Talked to the service manager about having the oil separators replaced aswell, he said he'd tell the technician about it. Technician looked into it and agreed they're worth doing while the car is apart. They tried ordering them through Mercedes but were told there on backorder. (Probably because other people are having this same issue with RMS and having separators replaced aswell) Tech doesn't want the car apart anymore than two days and they can't have it taking up a lift space for an extended period of time so unfortunately they aren't going to be replacing the oil separators for me. I called my mercedes dealer and spoke with parts department to see if I could order oil separators and was told they're on backorder aswell, so Chevy dealer wasn't making anything up. The pictures I got the Chevy tech has the whole drivetrain dropped (engine and transmission together). Tech said he'll be done with RMS today and car is atleast 2 days to put back together. They are supposed to be doing the upper main seal of the oil pan as well. Perhaps dropping the engine and trans would make it easier for him to work on than doing it still in the air? Heres some photos
Another update today from dealer Going to be delayed another 2-3 days, because Technician doesn't feel comfortable re-using certain gaskets for parts that had to be taken off to get to the upper main seal of the oil pan. They are ordering new ones from Mercedes. So will not be getting the car back this week, should be next week. Definitely have the feeling that they DO NOT want this thing coming back for any leak after having to do all this work.

Good. never reuse o rings or gaskets or seals, thats just asking for it.
My 2019 w213 with 46,000 miles has been out of commission for 45 days total now due to oil leak. The dealer can't seem to figure it out. Got it back 2 weeks ago, it was still leaking when I got it back. It's back in the shop today after only having it for 2 days. It's with Mercedes Benz Escondido. I don't really have faith in them. They said it the RMS leak and also said it was oil pan. I told them about the separators, but said they looked into it. They told me they pulled the entire engine out as well. I am not sure how this is gonna play out. I just purchased it first week of January. It's on a CPO warranty as well. I almost wanna tell them to give me my money back and keep the car. Although I loved every second of the 2 weeks that I actually had it at home since I bought it. There is nothing for sale anywhere I can find with the similar specs and color.

Thanks for the photos. The rear engine block bulkhead needs to come out to replace the RMS, and a necessary prior step is to separate the transmission from the engine. WiS calls for engine removal in this case, evidently also the transmission or the shop decided to additionally remove the transmission with the engine. It's always easier to work on the engine out of the vehicle vs. in the vehicle. The decision needs to be made the the shop or manufacturer whether achieving "easy" is worth doing all of the precursor work to remove the engine first.
The oil separators are visible in the photo of the engine on the stand. So close, yet so far away (separators on backorder)...

I feel the exact same way, car being in the shop longer after buying it than it's been in my own driveway. Fingers crossed your dealer can correct the issue and make it right the 2nd time.

Interesting plastic windage tray and oil pickup.
exact same thing my Service Advisor had told me. No easy way in doing this. That's why nearly 30 hrs of labor charged on my job.

My 2018 had a bad motor mount. It took the dealer a full month to fix it and that didn't require any work on the actual engine (just pull it enough to swap out both mounts). I figure service on these vehicles will always be slow.
What’s the drawback to living with a small oil leak? My E39 7 series always leaked some oil. Just keep on eye on the level.
Drawbacks:
- oily garage floor (solution: cardboard)
- oily driveway at friends'/relatives' houses when visiting
- filthy underbody which masks other potential problems or leaks
- lack of peace of mind
I guess if you carry around a piece of (clean) cardboard in your car you are good to go at friends' and relatives'. If you clean the underbody weekly or monthly you are OK with the third one. Not sure how to address the fourth one.

Same issue here. My engine mount failed at around 1000 miles on my brand new 2021. I didn’t know it was bad until I had to take the car back to get the Hermes module retrofitted and somehow they found that issue. Took the dealership here in Boston nearly 3.5 weeks to fix it. While it was clearly a lot work, almost a month for an engine mount is absurd. The paperwork said that the job itself cost nearly $4000 IIRC.
I'm in Toronto as well, where do you service the car?
I'm having mine checked prior to end of the Original warranty
good call. You never know … thus far lots of 18 and some 19 are reported in this and other RMS threads. Again, my dealer is not certain if this is warranty covered or not. Do push the dealer into it as warranty issue if you do have a leak.
i used to service mine at my trusted indy mechanic for the last 15 yrs …but he has just announced his retirement back in March 2023. So, i have no choice but to service it at the dealer until i can search out a trusted mechanic in the next few months.

If you’re speaking to me, I have no idea. The car was new to me and so I couldn’t tell any abnormal engine vibration or anything and I don’t recall seeing a CEL. I just took it to the dealer for the module and they told me they found that it was bad.
