Yep, thats the button I'm talking about.

Yep, I have that module, it works great. If that would solve this issue, thats an easy solution.

I am sorry that my friends are not responsive, I am guessing they are all busy or maybe I need better friends Well, anyways that one that replied to me I mentioned in an earlier post said he had to schedule an appointment for May to have the vehicle checked out. Until then, guess it will remain a mystery but I guess they key takeaway is that you are not alone on the problem or if MB Canada calls it normal like you mentioned then it is a "characteristic". We will see what happens.

In the mean time I hope you still enjoy your vehicle. This is annoying for sure but I am hopeful that the rest of the vehicle makes up for this for you.

For that module, it disables cylinder deactivation on top of auto start/stop?

SW20S

It remembers the setting of that button, so if turning that off solves your vibration, it will leave it off

W205C43PFL

I see. I wonder if OP tried it yet, maybe I will ask my friend to try it too then while he waits for the May appointment.

"This is annoying for sure but I am hopeful that the rest of the vehicle makes up for this for you." In a way I guess you're right.

Hey Vin, was wondering if the following is similar to the vibrations you felt?

2020 560 4M, 42k miles

I've recently began noticing a slight vibration (shiver) at various speeds from 5mph to 75mph. It's not ongoing, very inconsistent -- most noticeable when driving through a parking lot at 5mph, it lasts a few seconds then dissipates. The other day my wife asked if the vibration was the car or the road. Anyway, it's not significant enough to be annoying...my concern is if it gets worse or is an indicator of bigger/future problems.

Also, I began noticing this after the dealership installed new tires, rear breaks/rotors & fuel pump (recall) a few weeks ago.

I am having same issue with 2019 S560. Owned vehicle new Jan 2019 but noticed condition within past 1 year 2022. Dealer tried to flash software update 2 days ago for torque converter. Not sure it worked. Different, not as obvious, but still there. Condition occurs at all speeds when following steady traffic with minimal acceleration, just enough to maintain steady speed. Stops when foot off accelerator or positive acceleration. Vibration felt in steering wheel and seat with low frequency noise similar to subwoofer. Turn radio off to be sure.
I just noticed posts for similar, same condition. Has anyone found a solution?

The engine and trans mounts were replaced. I must admit that the symptoms of 'rumbling' effect were greatly reduced mind you, if you all remember, this rumbling was very apparent in ECO mode and almost disappeared when ECO was shut off. Was happening with Eco on and around 1100 rpm. I eventually sold the car for more than I paid for it and picked up a new loaded Graphite Grey E450 wagon, my 9th wagon! I go thru cars like a woman and shoes, may look at another S in the next couple years.

jekoda

Yeah, same issue on my 2020 -- slight vibrations when slightly pressing the accelerator, at all speeds. Based on your discovery of turning off eco mode the issue is non-existent. But dealership has approved replacing engine and transmission mounts under warranty, so might as well.

vinnybenz

Let us know the results of the mounts work and if the Eco mode still presents the problem after. Thx

vinnybenz

Hey jekoda

Any results?

Just got my 2019 S560 and one of my complaints is that it moans when driving between 20-30mph especially cold. Pressing on the gas slightly more makes it quit. It's like the transmission is already in 9th gear with the overdrive torque converter locked in. I'm considering it a normal condition. I going to try driving in sport mode and see if it rectifies the shift pattern. I'm sure it's a fuel mileage thing and any updates to the transmission will probably decrease it ever so slightly.

tbirdvet

This can be typical on some units but the dealer can check to be sure no codes.

Donnymac

Don’t over look motor and trans mounts especially if the car lives in ECO mode.

jekoda

Yes.

Decided to wait until 50k miles service to have engine & transmission mounts replaced, which was last week. Unfortunately, minimal change (with eco on). That said, I've been driving in eco off mode since reading your post last year. With eco off the problem is near non-existent, acceptably smooth. Was hopeful to see a difference (in eco on mode) with new mounts but just happy to have the eco off solution.

Are you guys talking about the "A" button (Auto Stop/Start switch) by referring to eco off? There is no Eco button on the S560 and naturally it is in Comfort mode all the time so there is nothing to switch off (unless you are talking about eco drive mode which is not the default mode anyway). From previous posts, you seem to be referring to the "A" button, but this is really not an eco-mode drive but rather a switch for Auto Stop/start feature so am confused as how this would impact your driving experience/vibration at low speed or light acceleration.

@RJC in a previous comment seems to know about this issue and have reported that there is a common design flaw in all S560 with 4-Matic (or 2017 S550 with 9G transmission) when in idle, but he was referring to full stop vibration vs you both are talking about light vibration when moving at slow speeds (which I don't think is normal at all and I did not notice in any of the S560 I test drove ever). However, as far as vibration at full stop idle, i noticed a common issue in 9 out of 10 S560 I had tested that there is very very very minor vibration feeling as the car gets to full stop with gear staying in D position, and RJC was right that this is only noticeable on vehicles with the 9G transmission because on all these cars I tested as soon as the car moves, or as soon as the gear is moved to P or N, or if you rev the engine slightly with foot on brake, that tiny sense of vibration in steering goes away. Nothing crazy and I think 80% of owners would not notice it unless you are an OCD type of a guy lol. The point is, MBenz continues to prove that they are way behind in the transmission game compared to BMW. I feel it is more of a software tuning that anything. But again, if you are all referring to vibration while car is moving, this is different and I don't think is normal because every S560 I drove is dead silent and buttery smooth when it moves, but the only noticeable OCD type of steering vibration in some vehicles is apparent at full stop coming to a stop light with full brake and gear staying in D (mainly since the 9G transmission was introduced). Am not sure about 4Matic vs RWD but RJC said it is only apparent in 4matic and it's hard for me to remember all S560 is test drove while i was shopping.

jekoda

Yes, the A button.

I agree with the OCD comment. I'm really not the OCD type. My problem is this near perfect car has spoiled me. Any new little nuance or slight vibration/noise in this machine is amplified due to the high standard of pureness I've come to appreciate. The slight vibration I feel would likely never be noticed in any other vehicle I've owned. My W222 with 48.5k miles and 3 years old is still a solid all around 9.5, and the ownership/driving romance has not fizzled.

SW20S

I'm putting mine in Friday for a vibration at idle in gear, feels like a bad motor mount or something. Completely goes away in neutral. Will let you know what the net result is

S_W222

but if it’s a motor mount then it won’t go away as you go N and it would also get worse when u rev or move the vehicle
a forum member here said that this idle behavior is normal for all s560 awd and that there is no way around it once your ocd look for it.
i test drove many S560 AWD and found this in most of them
could that really just a “by design” flaw!!???

Question: Does the idle vibration goes away if you start moving the steering left/right while idling?

SW20S

Motor mounts definitely can cause a vibration that goes away in neutral, no vibration except when idling, and its worse when the car is on a decline.

Haven't tried the side to side turning, I will.

Donnymac

Whats your odo and do you run with “A” on or off?

SW20S

33,500 miles, I run with A off.

It does also go away when turning the wheel left and right

S_W222

I know that we talked about this in the messages, but since the vibration goes away when you turn the steering, it seems that forum member @RJC is right about his previous post. Sounds like a “normal” (aka: design flaw) in all S560 4-Matic vehicles since the introduction of the 9G. Many have tried to replace engine or transmission mounts with no success.
Since it goes away with steering movement left/right, I don’t see how that is related to mounts. My hypothesis is that this might be related to axle componenets (which are only present in the 4-Matic) that fail pretty soon. When in idle, the movement CV axle/joins lose movements vibrates back into the steering. When steering is moving or the engine is rev’ed, the components settles and won’t move/vibrates, hence no vibration is sensed. I could be wrong, but it’s certainly a 4-Matic type of weird behavior. Could be a transmission bad tuning, but could also be bad CV joints that fail pretty soon in all S-class 4-Matics.
