Don't know the answer to the second question. I was just told "engine management software update."

So I stopped by the dealer this morning to check on my car. I asked my service advisor to look up the description of the Campaign. He couldn't print it but read it off his screen. The description said it was to correct a false fuel system reading which may cause the engine light to illuminate. There was no mention of changes to engine or transmission performance.
I guess I'll have to wait to get my car back to see if I observe the same as others have. I ran a VMI report in October 2018 and all campaigns were complete. This is the first campaign since then.

1) In comfort mode, I noticed the idle is slightly higher. I recall that when going from Comfort to Sport, the RPM used to come up slightly, and then again going from Sport to Sport+. From a stop, the torque converter seems tighter. It could be the RPM being slightly higher and the torque converter flashing sooner, more spark advance coming off idle, or the TCC to come on earlier. Either way the car is less lethargic accelerating from a stop,
2) In Sport mode, the car isn't as "jerky" starting in first gear. It feels like there's more torque management coming off throttle or the TCC coming in more gradually. Also I thought the car short shifted in Sport mode. I'm not 100% sure since I only went WOT a couple of times.
...more driving is necessary.

I just got my car back this afternoon. I did notice the following things:
1) In comfort mode, I noticed the idle is slightly higher. I recall that when going from Comfort to Sport, the RPM used to come up slightly, and then again going from Sport to Sport+. From a stop, the torque converter seems tighter. It could be the RPM being slightly higher and the torque converter flashing sooner, more spark advance coming off idle, or the TCC to come on earlier.

Campaign No. 2019020002, February 2019
TO: ALL MERCEDES-BENZ CENTERS SUBJECT: Model C-Class (205 platform) and AMG GT-Class (190 platform) Model Year 2016-2018 Update engine electronics (ME-SFI) control unit software Daimler AG (“DAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year (“MY”) 2016-2018 C-Class (205 platform) and AMG-GT-Class (190 platform) vehicles, an incorrect software could cause certain vehicles to exceed certain emissions requirements. An authorized Mercedes-Benz dealer will update the engine control unit software on the affected vehicles.
Prior to performing this Service Campaign:
• Please check VMI to determine if the vehicle is involved in the Campaign and if it has been previously repaired.
• Please review the entire Service Campaign bulletin and follow the repair procedure exactly as described. Approximately 2793 vehicles are affected.
I believe this is the true reason for Recall.
I will wait for a chance to do before and after dyno test, seems everything related to emission is going to nerf the HP and Exhaust note.
If I found out HP or exhaust has been nerf, I will do ROLL BACK my ECU software.

2018 C63S Sedan
I ran across a thread about software updates and the consistency or lack thereof with respect to dealers installing them. Just do a search. The fact is that I have a one year/old 2018 C63s AMG coupe that received an update of the engine management software a couple of days ago during a r-o-u-t-i-n-e 10,000 mile service and it profoundly affected the way transmission shifts - smoother, quicker and lower down in the rpm range. How can I be the only one?
You are not the only one. My 2018 C63S was done last Thursday, the 14th, at it's first year's service. It shifts definitely smoother and just feels different in S and S+. Less snap, crackle and pop for sure too. None in S, S+ is reduced. As another poster mentioned, the ECU may need to readapt before all is said and done but by that time I will have readapted too.

Looks like Campaign No. 2019020002 covers multiple software updates. We've now seen the following:
1. ECU software update due to residual condensation that may set off the CEL.
2. ME-SFI control unit software update since some cars may exceed emission requirements.
Can anyone that has access to the campaign recall list all the software changes they will apply.

I was at dealer today for replacement of voltage converter (Auxiliary battery malfunction message).
SA noted Campaign 2019020003 showed as due for my car. Description is same as image posted above.
I declined because I didn't want ecu software overwritten.

See the image of the service order for more details.
The car is definitely louder than before in my case.
The car shift up much faster in lower gears and the gear box is much smoother.
No exhaust popping in C or S. With my prior software you could hear low pops in C mode.
In S+ every time I'm in the 3000-4000 rpm range you hear a small bang or 3 pops. In 1st gear you hear a loud bang in the 4000 rpm range when you lift off the throttle.
Shifting up in S+ with the paddle you hear an aggressive sounds that you didn't hear before. For me, it's a little too loud all the time for me driving in the city because everyone thinks it's like several gunshots.
The car's overall transmission is much smoother, for example in S+ in 1st gear, if you let go of the throttle at around 2500 rpm, the car will coast at 2500 rpm, where as prior you could feel the torque and the car would slow down immediately. Now that the car coasts, you don't hear the 10 or so continuous exhaust popping sounds or exhaust popping sounds while engine breaking down a hill.
Overall it's a huge improvement, but feels less like a raw AMG car and much more refined now, except when in S+. I'll probably drive more in S+ mode now.

For almost all of my life behind the wheel, I was using a clutch and a shift. I was having difficulty getting used to the shift points of the C63s in S+ or in any setting. It was so different than the shift points I had used manually for many years. After the update, I feel like in S+ the shift points are more "natural", i.e. when I drive around town, the transmission shifts in the rpm range where I would normally shift. Now for the first time I am feeling comfortable with the transmission.
