I just posted on another thread. Maybe RMS failure? Will CPO warranty help?
I am a new owner of a CPO 2019 AMG E63S Wagon. Unfortunately I am not having the best of luck after just over 100 miles and 1 week of owning. I only drove it back from the dealer in San Diego to my house in Los Angeles and after a few days I have a Big puddle of oil on my garage floor. I can see the leak under where the center consul would be in the car. No idea where to start other than I will be taking it to my local dealer in Torrance, CA Monday for an inspection. The 2 times I drove it, it was the best driving car I have every had. So as you can imagine I am pretty bummed out.
Any tips would be greatly appreciated. It has 45,000 miles on it and the condition was brand new from my perspective.

if its under the center console it could be the oil pan but that is just a guess, let us know what it is.
I had an oil pan leak and was replaced under warranty.
Hopefully getting my 19'. E63s wagon back today. 46,000 miles with a RMS failure. The dealer is covering it under CPO warranty. Happy to have it back and not see that issue for a while. Took them about a week to take care of it. (Side note, I loathe the turbo 4 in the GLC 300 my loaner) can't wait for the car back. Will add the video from dealer under the car.
Do you think that it's just mileage or a parts defect?
like the other member had said, it is likely the design issue (pressure is too high) which leads to the failure of parts. Therefore, it will happen overtime ... probably nothing in the first 3 yrs. Mine failed exactly after 5 yrs @ 60,000 miles.
Might be a dumb question but... the oil separators aren't complex mechanisms, I'd be curious what exactly makes them stop working? If they are filling with oil, can the oil be extracted from them or can the be cleaned in place somehow?
For the cost/hassle of replacing the oil separators maybe there is a more creative solution.

Good question , picturing a filter of some sort inside getting clogged gradually then plugs up . Question is what contributes to it .. blow by , moisture , overdue dirty oil. It doesn't seem to discriminate on well/poorly maintained cars so who knows ha .
VAG separators have at least two check valves. The valves can stop working (plug) and pressure builds up behind them, and finds the path of least resistance. Apparently with the M177 MB 4.0 TT V8 this path is out the rear main seal.
Mahle is the supplier for the M177 vapor separator. It is a dead simple component - only three screws plus hose/tube connections. However, the intercoolers on some installations need to be removed or at least moved out of the way, which increases the labor time significantly.
The images below are from Mahle, the supplier of the M177 component. The images do not show the M177 separator but show at least 2 springs which control the "overpressure" check valves. There is also some "gauze-like" material in the assembly. I can imagine the internals of the separator and gauze-fiber filter getting gummed up and the spring/rod/valve assembly getting sticky. Good idea, bad implementation. As usual.
Separators are beta technology in the industry, car companies are still figuring them out.
First image is similar to the M177 component. Second image shows internals for the principal of operation.
Great info , thanks for clearing that up. Yeah surely some diy's will make their way around eventually on replacing these . Can't find much yet except for valvestuds wis attachments .
Digging around some more it looks like Alfas from decades ago use an oil vapor separator. So today's separators are a reincarnation of an old idea. And still not quite right yet.
Can these separators be replaced pre-emptively without dropping the transmission?
I believe the dealer does not drop the transmission. I see no reason to touch the transmission. Maybe @konigstiger can post WIS for the separator replacement?
edit: comments about transmission removal on this thread relate to rear main crankshaft oil seal replacement. Transmission removal is required to replace the RMS. Pre-emptive replacement of the vapor separators does not require transmission removal.

Yes there was some wis attachments floating around - maybe in this topic farther back.
The separators are in the front of the engine. Intercoolers & maybe some accessories have to be moved/removed
You have to ask whether extended warranty will cover this. My dealer (Servicing dept) is not 100% sure if this is a warranty item, I guess he would have to call up MB Canada to get confirmation.
Back in 2021, the extended warranty for our E63s price quoted was C$5,250 for +24 months // C$6,200 +36 months .. taxes not included
Not sure what the latest quoted price for that now
I find that the extended warranty doesn't cover a lot of stuff. Imagine spending $5-6K on extended warranty and something like this happens and you have to fork out another $6K...that would hurt pretty bad!!
Did MB say what was the root cause for this issue and is there any prevention from happening? Or is just the luck of the draw for everyone?
