Still waiting.
In the meantime some other issues have appeared. When I shut off the engine, the MFD says "Correct Tire Pressure with the tire graphic. The graphic of the car no longer appears on the MFD prior to start-up. I get an occasional chime now with no message. Once I couldn't get it into park until I opened the door.
I'm thinking that it may be the computer itself.

I get the same thing with the MFD sometimes when I turn the car off. It gives me the tire pressure indications. I just figured it was a fluke and that was it. I did notice that it started to do that after I get a lot of work adjusting my tire pressures over three or four days. I was constantly changing the pressure is trying to get the cold pressure just right for the best ride. I guess that's a coincidence, but I'm not sure.

Forget the tire pressure warning. I didn't think the cold weather here in Florida would lower the tire pressure so much. It was down to 32 psi all around. The "correct tire pressure" warning was real. I suspect it comes on at 32 psi.

The message that I got was not a warning, merely a reading. It had the same display that you would get if you want to get an accurate measure according to the tire sensors of the tire pressure using on of the buried functions in the MFD. There was no warning light on the dash and the message was definitely not a warning and the tire pressures were not low. The display came on every time I would shut the engine off for about two weeks. And then it stopped coming on. It was unrelated to temperature changes or changes in tire pressure inflation. It only came on for about a week, beginning about two weeks subsequent to my doing some experimenting with pressures. As the ambient temperatures have gone down here in Los Angeles the display has stopped. Therefore it is not a warning at all. Just some computer weirdness I think.

Who the hell designed and fitted this piece of **** ECO button.
I hate hate hate it, and wish I could remove it. I am in charge and
when I switch off it's for a reason, why do you have to sit in a traffic
jam with the bloody engine stopping and starting, just one more thing
before the thing drives itself.

* Stop Start Finale *
They tested a 2014 with the same results. Though I told them of those here, whose stop/start works, it made no impression.

Yes, as you take your foot off the brake, the engine starts. Do you need excessive pressure on the brake?

You can prevent the engine from shutting off even when the ECO light is green!
Just pull up to the stop very slowly with light pressure on the brake pedal. Let the car come to a complete stop but do not put heavy pressure on the pedal. The engine will remain running.
If you want to stop the engine, maybe because you are at a long red light, then just push harder on the brake pedal and the engine will stop.

Eco Stop Start Issues -- The mystery continues
Trying to figure this out Eco-Stop is like solving a murder-mystery... but I think this group is getting closer! I believe the answer/resolution is in the last 3 posts -- particularly brake pedal pressure and speed of each stop.
There are so many long stop lights in Northern NJ that I appreciate Eco-Stop -- when I can get it to work. My current opinion is that one has to stop fairly fast and press the brake pretty hard to get Eco Stop to work. That's my current best guess.
Furthmore, several times when I have come to a stop and Eco-Stop does not got on, I have found that if I then drive forward another yard or so (assuming I have the room to do so), and push the brake a bit harder, Eco Stop will then work. But even this extra effort to engage Eco Stop only works about half the time.
Here's one more of my own clues: On 3 or 4 occassions, after I have driven around for half an hour or more -- and Eco-Stop has not worked -- it DOES go on when I pull into my garage slowly at the end of my trip. How weird is that??!!!
Someone has got to solve this mystery -- please. I still only have 6500 miles on my 2013 SL550, so I have yet to bring my car into the dealer for an oil chance service, when I will ask him to help solve this mystery.

The tech guys from Mercedes said not to expect it to work as well as the new Chevrolets. The parameters were engineered too tight.

I think you are correct. My ECO symbol on the display only gets the green box sporadically. If it is green, it works but the parameters must be pretty tight to allow activation.

I have never had an issue with the Green Light staying on. I keep the Eco button on all the time, and the light stays green on all the time. Now, all I need is for it to work! :-))
If the activation criteria are too tight -- and I agree this sounds like the real problem -- why can't Mercedes' topflight engineers RE-PROGRAM the Eco-Stop software, to widen the activation criteria, so Eco-Stop works? Does any one have a contact at Mercedes who can contact the software engineers who can get this re-programing done?

I agree. I think the list of parameters and the criteria needed to activate the ECO system are too narrow. And I think that they could, indeed, be changed by a software update to the ECU in the car.
However, MB has a huge amount of inertia when it comes to making changes of this type. I think that there are very few owners who are complaining about this problem. For whatever reasons.
It would take a huge amount of complaints. But what they really look at is warranty charges. And this type of complaint seems not to result in a lot of warranty charges because the tech writers usually brush off the owner by saying that the ECO system is working ok and that is just the way it works. So the car never actually gets into the shop to incur a warranty charge!
We should all call the MB customer line in New Jersey and register a complaint there. Or.......take the car into the dealer and insist that they run diagnostics on the system, thereby forcing a warranty charge. Ha.

Time has come to trade it in for an SLS Roadster. It should be in tomorrow. I posted the following on the SLS section.
Mine is iridium silver with a black top. The interior is red.
Although I didn't need a lot of options, this car is loaded. Extended carbon fiber interior and mirror caps, AMG performance media, Bang & Olufsen radio.
The car should be at the dealer tomorrow. It is being shipped down from Ohio in an enclosed trailer.
From the dealer....
I DO HAVE GOOD NEWS FOR YOU. YES WE CAN GET THIS VEHICLE FOR YOU. IT'S THE ONLY ONE IN COUNTRY.
THANKS
