Have someone stand far (for safety) and still be able to see the engine, foot on the brake put the car in reverse rev it, does it move excessively, foot on the brake put it in drive, rev it, does it move excessively? That is the best way to determine if you need mounts.
On a side note, unplugging the oil pump solenoid also helped decrease (in my case almost eliminate) idle vibrations. Certain engine oils also quiets down the engine and decreases engine vibration.
Don't forget to check your transmission mounts as well.

Unplugging the oil pump solenoid? Sorry I'm not following you there.

Hmm
My car has this rough shaking at idle too, but very infrequently. I always thought it was just the active mounts wigging out because electronics and computers always wig out once in a while.
It is VERY intermittent for me, like, every couple months for one drive. Next drive it's fine and doesn't come back for a while.
Dang it, just when I was about to try my CPC module. Now I have to worry about replacing the axle in warranty first. <sigh> I waited until 160,000 kms on my old car to mod it, then got rid of it in a year. I don't want to wait again - but - man I remember all the warranty work my old car had and I can't "afford" that just for being a second faster in the 1/4 twice a year. Argh.

I wouldn't worry too much about the axles. Both of mine were just the CV boots failing but the axles themselves were fine. On my W205 it was at 52K miles and my W213 at 67K miles. That rubber is expensive! lol

Read the FAQ in the first post at least when you have time : )

I'm a lifelong modder, but this comes across to me as a solution in search of a problem. I know what I don't know and this one is not for me.
Thanks man!

Unplugging it leaves the engine running at full (normal) oil pressure all the time and since the valve is always closed, it never has a chance to be stuck open.

I understand your concern. I did it on mine and I am enjoying only benefits. If you read the FAQ, if the oil pump solenoid does fail stuck open due to debris, it can be catastrophic for the engine as it forces the engine in low oil pressure mode even at higher RPMs.

If it makes sense to you and others then go for it! This is not a train I'm a passenger on.

Yeah, I've read most of that thread and I get it. But I see a lot of possible solutions there for a problem that doesn't seem to exist. Two-stage oil pressure systems in engines designed for them don't lead to increased engine wear or premature engine failure (the same can be said for auto stop/start systems even though many believe the opposite). And I've never heard of anyone losing a MB engine due to a failed hi/lo oil pressure solenoid or that it's even close to a widespread issue, not to say it's not possible... I guess anything is possible.

not to worry, the station coming up you can transfer to line 2 : )

Yes, it is applicable.
That said, you are right, no one with an M177 reported results of unplugging yet in the survey: https://forms.office.com/Pages/Analy...g1Mkw1WkJVNS4u

keep in mind that some people with an M1 57 engine, the previous engine in the E63 W-212, and various other AMG models, got a check engine light, and the only way to circumvent this check engine light was to attach a dummy solenoid to the plug that you disconnect. That being said, it's unclear if the M177 disconnected will give a check engine light

Yep
First reported:
"Intermittent very rough idle in gear when stopped. Cowl shaking, feel it in the seat, muscle car rough. It’s “cool” but…
I told them check the front axles as I heard it could be that. Car is left overnight to hopefully duplicate this when cold in the morning."
https://mbworld.org/forums/w213-amg/...ml#post9031013
Diagnosed (what I don't mention is they smoke tested to find the leak):
https://mbworld.org/forums/w213-amg/...ml#post9031296
Fixed:

They also found after unclamping the turbos to do the fix, that the pipes were not lined up 100% and "under stress" when clamped. Rotated and aligned pipes, re-clamped with new style turbo clamps, smoke tested, and then did an idle re-learn after some O2 sensor resetting too. I can find the service record if someone wants the whole verbiage. I'm fairly certain they caused this exhaust issue dropping the exhaust to replace the transmission since right after that fix I reported slight pre-cat smell, but at that time they said "looks good to us!"
