I can bet my life on it that it is just a selection in the software to have it either on or off at start of the car. It probably also has an option that it keeps it at setting it was at when the car was turned off. They would be stupid programming it in just one way. Some country might even have a law saying the driver must have the SAY on this as how it works.
The question is if anybody can bend MB`s arm to get them to change the setting?

I agree it is related to battery. I was happy using ECO stop for two weeks then it seldom turned GREEN. I guess it is because HID headlights consume too much power at night. So now I always turn ECO off at night and then turn on ECO on in the daytime. But it is quite annoying that when engine starts automatically (not by releasing brake), it feels like an earthquake that always shocks me.

It can be totally disabled by Xentry DAS. But MB service probably won't do this for you. You have to find a private car shop to turn it off for you.

I like the system but it's kind of an on and off thing. Even when all of the requirements are met when ECO is on, such as the seatbelt being buckled and the A/C being to a low setting, the engine doesn't shut off. Sometimes it does. Also, I wish that Mercedes would offer a standard off mode for ECO because there is a lot of stop and go traffic in LA and it does get pretty shaky.

Same here. Would welcome a mod if the eco button remembers it's last setting
We bought a 2014 E350 a couple of weeks ago. The wife does most of the driving and HATES the start/stop/restart with that delay of the restart. Part of her procedure is to push START, push ECO, press brake then engine starts.
The starter may be made more rugged, but many other devices also surge upon restart. The more a device is used or restarted, the faster it wears out.

I don't think all people are lazy. It's just annoying sometimes that I forget to turn it off until I'm at a stop light and the engine shuts off on its own.

The point is that cruise control is off by default while ECO is on by default. This is bad. (At least BMW has ECO button positioned near ON/OFF which is easier to default)

Why is the rear lock unit different and special in North America where you have to pull the pin to unlock it, it won't unlock from the handle?
Why can't I lock the car with the keyless-GO while the engine is still running? At least BMW let's you do that?
Why won't the seat heater stay on and not reset if I only get out of the car for a minute? BMW does!
Why, why why? It's because it's a Mercedes and their engineers decided to do it this way! Suck it up buttercup! Or try to be special, make their focus group and whine to them. This right here does absolutely nothing.

One of the reasons I recently traded my F30-335i was the placement of the *** (auto stop start) button. On several occasions, I had brought my car to a stop in heavy traffic, waiting to say turn left. Unexpectedly, the engine would stop. I could not see if the telltale light for *** was on or off because it was not visible. I would then go to re-start the engine which had by now shifted automatically into park, then re-engage drive with BMW's overly complex shifter and finally be ready to make the turn. When all of this happens in heavy traffic, it can be very unnerving and darn right dangerous !At least Mercedes has placed the *** button in the centre of the console where the green light, indicative of *** being active, is clearly visible at all times. The indicator light's visibility does not depend on the position of the steering wheel !

After driving new 2014 E350 Sport 4-Matic for four weeks now, I seem to turn off the Stop/Start feature more often than not.
I don't like being in traffic with my engine not running, doesn't feel right.
I can't believe I'am saving much gas since I don't drive much in traffic.
I've owned 8 new MB's in the last 24 years and I wouldn't be buying MB's if I were trying to save on gas.
What does anyone else think about this feature?

You are more patient than most. What is the failure symptom when "it does not always work as it should"?

There is a complicated algorithm the computer processes to decide whether ECO start/stop should be active. It is not simply supposed to be enabled when you start the car. It takes into account things like: is the motor warmed up; what is the interior temperature compared to the exterior temperature; are you actually in stop and go traffic; are you coming to a complete stop or simply slowing down or making a rolling stop.

My first experience with ECO/Start/Stop was on a BMW 5238i and I didn't like it. Way too rough starting up. The fact that it was a rental may have had some impact on this, don't know.
On my E250 it's much smoother. I don't mind it kicking in at all. You barely notice it starting up and smoothly accelerating when you punch the accelerator (I usually invoke the brake HOLD function too).
I do notice it not kicking in sometimes, but that's usually when the A/C is on or the car isn't warmed up yet. Doesn't bother me.

That's going to be difficult as it's becoming standard on just about every car in the luxury class. Heck, it's on almost every car in Europe. At least Mercedes does it right with a dedicated *** battery and queuing up cylinders under compression so a spark helps smooth the restart. On BMWs, they just twist the starter... No different than you twisting the key and putting it in drive. That's why theirs is so rough.

I do not like the eco button. Car hesitates. I am looking on how to disable the button. BMW has a fix to disable the button. Mercedes should also. The hard part is to find someone who knows how to disable the button. I want to be able to turn it on when I want it on. I did not buy a car that takes high octane to save money on gas. I want performance not hesttation.

I had a GLK loaner a while back that had the start/stop function and I thought it was pretty cool, worked very well in my opinion. I wish the E350BT had it, I think it would be useful to save on fuel.

I am on the fence concerning the ECO feature.
I don't mind it when stopped at a street light.
I don't like it when I pull in the driveway and I'm about to put the vehicle in Park but ECO cuts in. Vehicle goes in Park and engine comes back on.
I don't like it when I am waiting to turn left into my street and am waiting for opposite direction traffic to clear and the ECO cuts in.
I find myself selecting/de-selecting ECO under certain scenarios.
600 km's into my E250BT......

I don't think I've ever actually put my E250 in Park using the gear shifter.

C-180 2016
I got a C-180 last Aug, 3 month latter Mercedez dealer place a mouse panel on the car but it start to show conflicts with ECO mode and air conditioning system, they said Eco mode Start/Stop mode has many rules but didn't give me all the instructions and conditions, I didn't find it at owner´s manual.
I´m worry it produce an electrical problem or something related, can someone give me an orientation about what to do, please
