ECO Mode
So I've noticed that my 2016 E400 has an ECO mode, so when engaged and the car comes to a complete stop, it kills the engine. I was thinking the other day this can't be good for the Starter/Engine to be cut off and back on all the time. What are your thoughts?

Well I will say the starter of the vehicle is not used with the ECO mode nor is the battery used to start it.. What actually occurs is the piston that is stopped at the highest point in the cam gets a short burst of fuel-air and spark and the car turns over when your brake is released Although I am not a huge fan of the engineering itself as I am not sure it actually saves any fuel but rather saves emissions. I just turn it off when I am going to do heavy stop and go traffic on highways etc.
Not sure this is true but I may have heard they are going to discontinue the ECO mode in the year or so but not truly sure.

Personally, I like the Eco feature and have observed that it definitely does improve my fuel economy. I was speaking with the shop foreman at my dealer just this week, and he confirmed that (as mentioned above) the time-honored starter cranking action is not used to start the engine from an Eco stop. This feature is relatively common these days (not unique to MB) and I would be surprised if they discontinued it because I think they need it in order to comply with minimum fuel economy requirements across the model lineup.

Mr. Toad, yes like it very much as well while I have not truly analyzed the results, I do think its more about emissions than fuel consumption. I would use it more if it had some sort of delay when stopping like a 5 sec delay etc. If one lives in a high traffic stop and go scenario like a bumper to bumper scenario it would make sense of a delay feature. I know I am being picky but not everyone enjoys only living right off the Autobahn, LOL
Now lets hope no one starts another thread for the remote start feature... LOL
Take care and hope your day is awesome.. Cheers Mike

Ok have to say one more thing about the ECO Mode and I will never post again on this topic... LOL
Everytime I come to a stop the engine stops, then I place it in park and it starts again then I shut the car off via the ignition... Pls no one tell me that its saving gas when its starts and stops consecutively within seconds.. LOL As per my previous post, why I suggested they have some kind of delay to accommodate for these types of events.. Ok now I will stop....
Cheers..

Cause the car is still in drive... Like pulling into a parking space... Once I stop before I place the car in park the engine stops with the ECO mode. Then after I place it in Park the car starts again...

Just get in the habit of keeping your foot on the brake pedal until you shut off the ignition. The restart is triggered by the brake pedal, not the transmission. So, hold the brake pedal, push the Park button on the stalk and push the start/stop button. Then release the brake pedal. No restart will occur...

There are lots of other things that can make it a no-go as well, but battery condition is the most common.

What exactly do you mean by "not working"? Does it never shut the engine off, or does it only do it in certain circumstances?

If the green light on the Eco button is never illuminated, then I don't think the problem is battery-related. The dealer replaced my battery under warranty when the Eco function was not regularly shutting the engine off, but the Eco light was always on (indicating that the system was active). In my case, low battery voltage was causing the car's computer to keep the engine running in what would otherwise be "shut off" situations because it was trying to charge the battery.

In my experience so far, it's a complex and problematic system. The software controls that tell the system when it should shut the engine off have to continuously monitor an extremely lengthy list of parameters, and if the current value for any given parameter is not within specified tolerances, it's not supposed to kill the engine. For about two months now, mine has been shutting the engine off within a minute or two and less than one mile after startup, with the AC on Auto and outside temperatures in the 98-105 degree range. When it kills the engine in those circumstances, the HVAC system continues to blow at the highest fan speed, but the air coming from the vents is extremely hot because the AC compressor stops turning when the engine shuts off. According to the dealer, the Eco system should not kill the engine in these conditions, but it does and they can't figure out why.

I never really cared for the ECO mode, but after driving other car manufacturers implementation of ECO, I really appreciate how smooth the MB system is. Add the brake HOLD feature and I find it hard to beat.
