Tell them exactly what part number to order. It’s your money and your car.

bobblehead

yeah. If you ask and SA tells you they have the older part #, then that might be a flag for you to be concerned.

Thanks for posting your update. Just to be clear about the extended warranty, it was the "factory" Mercedes extended warranty, correct?

sixfive

I believe so as knowing me, that's what I would have purchased from the get go . . . Have not had time to look it up in my contracts s as I'll have to find those first . . .

b0rderman

Was it the Mercedes service techs/advisors that notified you it was going to be covered under your extended warranty? If so, then that would indicate you have the MB extended warranty.

sixfive

sure was. I kinda doubt that would offer aftermarket while sitting in showroom picking up a new AMG

b0rderman

I believe this might be the first confirmed instance of the MB extended warranty covering a RMS leak...which is great news because I have the MB extended warranty as well

HBerman

It's listed in the covered items for the Extended Warranty brochure at the end of the list.

just received this from the SA:

I have not had part list them in your repair order yet. But these are the parts number on the S63 I currently have coming. With this being the same engine im assuming it the exact same part numbers
LEFT: A1770105003
RIGHT: A1770105103

they don’t match up with what was previously posted so ….. ?

HBerman

Yet another set of p/n's. Not the same as previously posted.

crankcase vent valve .. and there is even a newer one that replaces the mentioned


i looked at my invoice, no crankcase vent valve was changed out.

b0rderman

Yes and that offers some assurance, but the actual policy language does not include that list. From what I remember, the policy language defines what is covered as all things that are not named in the "what is not covered" section. In any case, it's great to have a real-world example to point to.

sixfive

This is what my SA was able to come up with but it looks like I’ll be waiting a while til they actually get here. Picked car up after brake job and a B service but SA wasn’t there, supposed to call me on Monday to discuss further steps … numbers certainly don’t match up with what you guys have posted …. ?

the latest: just got off phone with SA, Oil Separators backordered til at least middle of July, likely longer than that . . .

What engine numbers are showing the rms problem? The m157 or the m176, m177, m178, m278. Thx

SilverE5588

M177 , unsure on the other variants. Negative on the m157.

chassis

M17x 4.0TT hot vee V8.

Not the M157 5.5TT or M278 4.7TT cold vee V8s.

In case anyone is interested, my GLC63 just got diagnosed with a RMS leak. 2020 with 25k mikes. Glad I’m still within the factory warranty.

chassis

Sorry to hear. Did the dealer state the cause is failed vapor separators?

Prago

They haven’t really begun the work yet. I’ll definitely update this thread when I learn more.

theboogers

Curious what climate these cars are operating in? Are your winters cold?

Prago

I live in Seattle. Winter is not typically harsh here.

theboogers

I’m in arizona with no problem now. Just wondering if cold would speed up things. Thx

sixfive

winters here in Idaho are a bit on the cold side but we've lived here only for a couple of years and I haven't most miles in this climate. Oregon was not quite as cold but much more humid . . .

ffejnotrom

Im in Arizona as well.... However I have a 2019 G63 AMG @30k miles on it. I noticed it in the last 1-2 weeks, and its just recently started to turn into the normal AZ summer 110* plus. So maybe the heat made it worse? Not sure.

Noticed some oil on my garage floor. Looked under and definitely has some oil residue on the covers/area where transmission would meet the block.

I have not had it diagnosed yet, however after reading all this, i'm about 99% sure it's a RMS leak.

So add the G Wagon to the list, and there is a thread over there as well.

Quick question for those with the problem, not that I plan to wait very long, but is there anything to worry about if I can't get it repaired ASAP? Am I able to drive it still for a week or 2 until i'm physically able to have it checked out and repaired?...other than, of course the drops of oil in my garage.

I just don't want to be driving it and blow the RMS completely out and have oil everywhere and a blown motor.

I'll be demanding they replace the separators as well. Clearly they know this is an issue, maybe a class action lawsuit would get their attention.

Also, anyone have any luck regarding coverage the emissions warranty if the bumper to bumper is expired?? The emissions warranty is longer isnt it?

bobblehead

Have a bottle of two of oils and monitor the oil levels

My process from seeing oils on the garage floor to diagnose to actual repairing it took nearly 3 months
