And in any other mode, which for me really means S+ cause that's what I drive in until warmed up, I don't notice any jerky downshifts.
But man... Love that race mode.
I hear the same mid-high pitch humming noise.
It's not stopped for a while even after turned off. Seems not related to any function. And sometimes it's not started immediately after ignition. If opening the hood, I can hear a bigger sound close to passenger headlight. Any thoughts?

Just kidding but you get use to how to drive it and you will be mostly smooth after a while.
Coming up to a stop and in 1st and the clutch opens and the light changes before you stop and you get back on it and the clutch closes again and you can get some jerkiness if you are not careful. but you learn.

You should start checking it each morning cold so you get a idea on use if any.
I got the low warning twice long ago and neither time was it low.
1st visit - car in to MB dealer - They were told to update software by AMG. The car apparently kept rejecting the software. Turned out their "Star" software needed updating (I assume their system for loading software to cars). So they updated. I got the car back - but not fixed.
2nd visit - had a strop and told them as this is the third visit - by law in UK they have to replace car.
They sent diagnostics to AMG who told them the new software was still not loaded and is corrupt. Suspect the new Star system does not report failed update. Software reloaded - diags sent to AMG and AMG confirmed update.
Now driven for 5 days with no error.
Hope this helps.....
That's what made me a little wary of my C63. Right now I think it is a low usage issue, but I will watch it carefully. I hooked up a battery charger on Friday and gave it a good top up, so it will be interesting to see how long it will be until the message reappears. Strange that you are having similar issues with daily usage.
I'm guessing heated seats and heated rear window can't help, but hey, it's been cold outside, so these things happen. I have always turned off Eco mode, because continual start/stop of the engine can't help the battery, unless of course, they have a low current option in Eco mode to stop that happening.
Keep in touch....
curious cause I had to put my car back on the battery tender after a month .
I've been doing short drives with the heated seats on and rear defroster on.
also running the stereo while vehicle is off for short periods doesn't help ether.
I think theirs a tsb about this
this will definitely choke the engine like you been experiencing.
also make sure your running top quality fuel 93 octane.

or if your diy guy look at it your self.
also the ecu mapping might be corrupt might need to be reflashed by Mercedes.
You will also see the boost screen in front of wheel not going up all the way.

- No gearstick. 18 months now and I still hate using the steering column stalk
- no stereo volume indicator;
- Noisy climate control
- In Comfort mode the car lugs off in second gear
- In other auto modes the car starts in first but holds gears too long for regular driving;
- In manual mode there’s no stop/start function;
- Clutch slip when driving off after using stop/start.
- Handbrake seizing every time when the car is parked overnight after wash
- hubcaps on 5 spoke star alloys falling off or being stolen because they are easily removed
- heavy steering
- Alcantara steering wheel
- Suspension’s comfort mode is not comfortable
- Can’t program race mode exhaust with everything else in comfort mode.
