2018 with 50k miles and a bad rear main seal. Dealer has done a few of these but hasn’t done anything with the oil separators on any of the repairs. What are you guys seeing to know that the oil separators are a problem? I may do them myself if it’s needed.
I first noticed oil on the garage floor. Dealer replaced the RMS. A month or so later my car started to make what sounded like a clown horn. They said the oil separators was causing a build up of pressure which then caused the RMS to fail again.
For sure on a maint. item the way it seems to be going . The separators are not expensive , unsure how labor intensive it is. Since these rms leaks seem to be in the 40-50k range - maybe around 30k is a good time to replace them.
everything is labor intensive. Dealer was going to charge 5k for the oil separators and 5k for the RMS.
@Valvestud Hey are there any wis documents on replacing the oil separators on these m177's by chance . Vin is just a random for sale 18 E63 to use for reference WDDZF8KB8JA458941
I don't think it is rear seal failure. There are bunch of things above back of the engine running of camshafts, and failure of any seals on those could look just like that because of the gravity

i can’t say for sure about others, but my RMS definitely failed… and the car hasn’t leaked a drop of oil since replacing.
does this seem like a RMS Leak? My thought would be that it would be coming out if the bottom, seems pretty high up, but could be wrong. Also the rear crankcase cover with seal is showing as being discontinued. So not sure how to fix this… lol
I am in Canada and out of orig. factory warranty btw. Dealer quoted me:
15 hrs (roughly 3 days) x $170 shop rate = $2,550 Cdn + 13% taxes on labor alone
parts of around $400 + taxes for the RMS
(Tech will evaluate the oil separators when he opens up the tranny/engine. If they need to be replaced along with any relevant parts, then parts & labors are extra)
Prelimin projected total $3300 Cdn. (or roughly $2,500 US)
I asked for any breaks but was not given any.
Car will be at dealer for about 4 days (3 days for repair and probably 1 day for the tech to test drive)
I just got my car back after 6 weeks. The oil separators was causing the rear main seal to fail. Which meant Mercedes wasn’t going to cover that part under warranty. Eventually they agreed if not it would have been a $10k fix.
My 2019 E63S AMG is in the shop for the second time for oil leak. Rear main seal replaced about a year ago. Now they’re telling me it’s oil separator failure. I have CPO coverage until December 2023 but am being told this will not be covered. How did you get them to agree? It’s aggravating that they don’t want to cover this since it seems to be a common problem.

My service guy is super helpful. I was very fortunate. I honestly didn’t push them too much on this. I let them take their time with trying to figure out a way to make this repair happen. I only expressed my frustration and to ask them to help me out with this considering the rms was already fixed a few months before (under warranty) before it failed again due to the oil separators.

My car is currently with the dealer and they have inspected the oil separators with no problem, so they have advised me of not to replace them and simply doing the seal as that should fix the oil leak. The car will remain with them as they have to wait for some bolts to be flown in from Germany and will likely take two weeks time.
