E63 AMG 2014 ECO mode deactivated after one stop/start
I would normally pass about 5-6 stop lights in the New York city and engine would stop/start automatically this summer with ECO mode as it should. A while ago, I noticed, ECO mode would turn off automatically, when the engine was restarted at the light after one stop, and would not turn on even if I press the ECO button manually. It is not like ECO mode is not working, but it is strange that now ECO would disable itself after one stop/start at the light. It is like ECO is working only at one stop light. Please let me know if this is something has to with battery being not fully charged? If I turn off the ignition completely and start again, ECO mode would come back. Anyone have similar experience? Thanks for your input.

when this happened to me I had a bad crank position sensor code and they replaced it and I never had an issue after, this was when I had about 600 miles on the car ...
about 14 variables have to be the right number before eco shuts the engine down but it should never deactivate itself to the point where the button light goes off

This just started happening to me as well, however what I noticed is that the light itself is off when I start the car. Seems to happen more often when I don’t drive the car for a few days. It works as it should after 1st start up. Leads me to believe it might have something to do with the aux battery? Heading to the dealer in a few weeks to have it looked at.

it is abnormal for it to disable itself like that -- meaning the green dot on the eco button doesn't light up

Yes, I have not been driving for couple for days, and I only make short trips around the area. So, may be battery was not charged fully. But, if it is a case, then it should not be activated in the first place. Thanks for your input.

Turn the knob to S or S+ and forget ECO... that's why you bought a E63! Problem fixed! 
How much fuel does "shutting off the engine at a traffic light for 45 secs actually save anyone? I feel it's more of a drain on your battery more than anything...
Merry Xmas, all!

Ok. Thank you. Makes sense. Will check out the battery. Is that battery covered under CPO?

You are absolutely correct. However, starting the car and hitting that green button has become a habit. Not having to do that anymore makes you wonder why, and whats causing it.

Thank you all your messages. If I understood correctly ECO Start/Stop system is ideal for situations where there are prolonged stops, but is slightly less efficient on short, frequent stops. I had very short frequent stops so is it possible that software system has learned that it was inefficient and adjusted ECO to work only at one stop? I measured the auxiliary battery with multimeter and it was 12v+ so battery seems to be fine.

BTW - there is significant additional wear on the engine doing the start-stop thing, and many (including me) don't like it at all. And as discussed above - doesn't deliver any real world fuel savings. I have disabled it - or rather - have it disabled by default and I can turn it on as needed.

Nope - wish it was that smart! It's more related to engine temp, battery charge, etc.

Liking it or not, a simple push of the button disables it. For myself personally, I like it on long, traffic stops.

Problem solved after replacing both batteries (main and aux), but something very annoying about the MB dealer. Quoted $700 for the batteries, but it end up $850 and when I asked, $150 additional charge was for diagnosis. But the service manager never said about additional $150 when I spoke. Is that normal for the MB dealers do charge for diagnosis on top of your service? Normally when you do the work with them, diagnosis is waived.

I feel like my battery is dying too because my car hasn't shut off at any stop lights since summer time. I wonder if there is a way to get this covered under warranty. Pretty sure it's battery problem that's causing my auto start /stop not working anymore since reading your post. Sometimes i have slow cranks to start car like dying batt.

Mine is 2016 so still on the 4 years factory warranty. My eco light comes on green, but the car never turns off. In the summer it'd stop at every traffic light, but since Oct, I never notice it turning off anymore. Sometimes when I make short trips, my car cranks kinda slow like a car with dying battery. I took it to my mech and he checked the battery said it was okay. I'm thinking it might have something to do with my dash-cam parking mod draining the battery out thus eco mode not working. That or dying battery.

hate to break it to you buddy but it definitely wears down your starter. take it from a guy who had to have his starter replaced... idk what articles you read but it is not like the bmw stop/start that has its own dedicated starter. its a useless function that does more harm than good. and it was only included to appease regulations. you can of course use it at your own risk but consider all of these factors

Did you meant MB dealer charged you for the battery while under 4 years factory warranty?

i personally find the ECO function useless living in downtown Chicago where i'm in stop and go all the time and any stop light is maybe 30 seconds of waiting. ECO was not a reason I bought the E63
but if your battery is bad and you are under factory warranty then get MB to give you a new one regardless if you use ECO going forward or not !
