I did not take up the offer to pay for MercedesMe after my trial period, and now I see it's going away all together. It will be pretty lame if M-B doesn't include our B's in whatever app they make for the EQC, but I don't have high hopes.
I don't know about you, but for me the MercedesMe app was flakey, slow and generally useless. I guess I enjoyed seeing my car's present charge, but I generally knew that. And when I plug in to a charger at work I know it will be 100% when I head out to drive home.
BUT, I did appreciate being able to start climate control remotely. That was a really neat feature. I also like that button you can press on the dash that keeps climate control on after you leave the car, but it's not quite the same thing.
In my search for some way to replace MercedesMe I stumbled across a feature you may have missed. You can configure the car to start climate control when you UNLOCK a locked car. So I am dreaming of wintry mornings when I will look out the window at my frozen car in the driveway and unlock it a few minutes before I leave the house. I've even found it useful when simply walking across the parking lot on a hot day, I activate it as soon as I can. Those extra few seconds of the AC running actually make a difference.
This is in the manual under "Pre-entry Climate Control via Key" (page 121 in my manual). You enable it from settings on the dash display.
I also see something about "Pre-entry Climate Control at Departure Time" which looks interesting. I haven't tried that yet.
