2015 S550 ROUGH IDLE--DOES YOURS DO THIS?
I am getting a "nervous" idle. It's not enough to show on the video game tach, but it's annoying. I am running 76 premium gas. My W221 never did that. Anyone else have this problem?

My car is smooth as butter. I have to look at the tach to see if it shut off or is running, you really can't tell. Perhaps the regular gummed up something. I doubt it would happen so fast but maybe. Still couldn't fathom putting regular in an S class though....

So wait, regular was used and now the car idling rough? Why in the world would anyone buy a 100K and then skimp on gas is beyond me. I don't get the point of threads like these.

To this point, I was at the dealer this morning getting a wash before the gym, guy came in to get his car washed (2015 S550) and complained "when I am at a light, the damn engine turns off and then turns back on, there is definitely something wrong with this vehicle you've sold me"

On the subject of running low octane fuel in your car. Don't listen to anybody, keep doing what you're doing, I'm doing the same thing.
On a secret note, I'm peeing into my tank on regular basis. As long as it contains high levels of ethanol (as mine does), you will be fine and you will continue to save money.

Just curious, what's annoying about it? I find it shuts off with barely a peep and startup is seamless. It saves a good amount of gas in stop and go driving...

Well, like so many things about these cars, I guess it's a matter of opinion. I find it very annoying and I do believe, that if we took a poll, most folks on this board would say that they would much prefer being able to turn it off permanently. In addition to finding it annoying, I dislike these "big brother" kinds of things. I like to be in control of my vehicle, not the other way around. That said, if you like it, that's great and I'm happy for you.

rather basic, first tier to implement. Believe it or not, MB's electronics are not bulletproof.

The phrase that every tuner does it just BS.

2015 S550 Idle
I am getting the same rough idle when Eco is off either in Park or at stop with foot on brake. The only way I can describe it is that the car gets a shiver. It can happen when car is cold or warm. Nothing shows on the tach, but you can feel the car shudders.
Techs tell me they don't feel it.
