Got my 400 in Nov and the ECO never worked at all all winter. Now with the warm/hot weather, it hardly works at all. Been to the dealer 3 times to no avail. Called Head Office and now awaiting the results of the diag that the dealer did the last time there.
Anyone else with this problem? I know that most would prefer to not have ECO but this problem makes me feel that the car is not 100%. Otherwise the car is great!
My daughter has a C300 with an ECO button that when engaged turns the engine off at stops providing she has more than a 1/4 of a tank of gas. Is that what you have?
i have a 2016 GLE 350 and my vehicle doesn’t have the ECO button but it does display ECO information in the display area between the speedometer and tachometer. I can never get a feeling for the bonus mileage I receive. I kind of make a game out of the display and try and close the circle which I guess means I drive equally with a lead foot and coasting with the wind to my back.

My 400 eco start/stop will start working by the time I reach the first stop sign in the morning. And it's only about 1/4-1/2 mile away. Something is apparently wrong with the dread, I hate it, it should be outlawed, makes my car lunge, does it really save that much gas, eco start/stop.

Well I hope MB HO has some answers this coming week, very frustrating.
I also own a GLE 250 diesel year 2016 and my problem is that every time I disable the ECO it comes back on every engine restart. This really annoys me and I don't see real benefit from it appart from ugly cold, stop and starts of the engine.

That's how its supposed to work, so it's not really a problem if it's working as designed. In my cars with eco, I have programmed a setting that bypasses eco, but that too requires I select the custom setting every time I start the car.
Well after five trips to the dealer, the problem was fixed. I only wish that the dealer had done a diagnostic report on the first trip . That report was sent to MB Canada for their tech folks to analyze. The report showed a problem with the driver seat belt connection. In any case, MB told the dealer to replace a sensor on the battery.That seems to have solved the problem. I strongly encourage you all to call MB's country head office if you feel the dealer is not tackling the problem correctly. It was my THREE calls that finally got MB and the dealer to do it right.
Well about to make my 7th trip to try to solve this damn problem.Going to check radar sensor, connectors at the ME, and 'teach' throttle. Absolutely disgusted being a guinea pig for these amateurs.
Made my seventh trip and still they can't resolve the prob. they're now counting on the German techs for an answer. Mind you all, I'm not crazy about the ECO feature either but because the ECO depends on so many variables to work, I just feel that the variables may cause other problems. I want the vehicle to be 100% as it should be for crying out loud!
Good luck to you - as other have said - ECO will only shut off when all measuring parameters are met - so like in one illustrative case one minor sensor prevented "full" use.
For the other's that have commented about not liking ECO - the "preferable" ECO operation is "if I choose ECO off, then when I start the MB the next time I want ECO off automatically" - and "if I choose ECO on .. vice versa).... and the eBay OBD module programmed by Vladimar does effectively reprogram the ECO that way... like $120...
Thank you for the reply. I have sold the GLE last Nov. HOWEVER, I purchased a 2016 CPO E CLASS E400 wagon in May and lo and behold, had the same darn eco problem the moment I drove off the dealers lot. Well based on the previous bull I had to go thru, the dealer knew exactly where to look, THE DAMN BATTERY! Replaced it and problem solved.
I have a 2016 MB GLE400. I bought the car about a year and a half ago. The ECO button never worked (it was never green/engaged on my dashboard, even if the button was enabled at the center console).
I took the car to the dealer, they said the batteries were faulty, so I had replaced both of them (the main and auxiliary), still no luck. One of my friend is a mechanic and he ran a diagnose again -- no errors/faulty codes were found. Does anyone else know what the issue may be?
A second issue that I've been having with this car, only during hot summers (when over 85 F), is that the idle speed suddenly increases when turning on the A/C. Again the damn dealer said it needs to be done some programming for the engine/transmission, it cost me about $400, could not really test it when took the car out because it wasn't that hot. Now this issue obviously did not go away. I even contacted MB and asked if that is a normal behavior or not, and they suggested taking the car to the nearest dealer.
I paid around $1700 with reprogramming, replacing both batteries, diagnose with no success.
I would gladly appreciate if someone else has some other suggestions that could possibly fix my 2 issues.
Me thinks you're getting milked! After nine visits and luckily under warranty at the time, it was finally determined to be a sensor connected to the battery that wasn't working. They changed the battery and sensor together. Then the ECO worked properly. Since then I have had a 2016 e400 wagon and now a 2019 e450 wagon, both have had the same damn problem.

Thank you!
My eco hasn’t worked in quite awhile. I’m guessing for probably the last year and a half. I’m at 70k on the odometer also. What is yours at?. As for the higher idle when turning on the A/C, mine does that too. I’ve even noticed that it takes more to stop (brake force) the car when it’s hot and the ac is running. I just assume it’s the smaller engines having to work harder to do more stuff.
Things sound pretty normal to me.
with my GLE it only works properly for 6-8 months before needing a new battery.
Ecco stop/start is a pestilence that needs to be expunged like the plagues of old. The system measures the battery's condition and will not operate if the battery is even slightly degraded so you will be forever replacing expensive batteries for a minuscule gain in fuel economy. Add to that, new starer motors and net, net, you will lose in the long run. Get one of the OBDII or Can Bus interface defeat units and get rid of it once and for all. I thank goodness that none of my vehicles have it.
FWIW... I bought a 2017 GLC 250D at 9 months old that needed a new starter battery and now own a 2016 GLE 250D that also needed a new starter battery to cure the stop start fiasco.
Both thankfully under warranty....cant believe my UK cars have the same batch of supposedly faulty batteries as you guys in the U.S.....hmmmmm
I've had 4 MB's in the last 4 yrs, 2 new, 2used but MB Certified, all needed new batteries and ECO sensor. Where is MB buying these parts from, Outer Mongolia??????????
