I reached out to my service manager about the software update to support charging at Tesla Superchargers. He said there will be an in-app (Mercedes-Benz App) message tomorrow, February 4th, notifying customers about the NACS toggle feature. Then a message will appear in the head unit (MBUX display) that a charging adapter will be available to purchase at your local dealership.
I specifically ask if I need to bring our 2023 EQS 580 SUV in for a software update and he said they didn't yet know which vehicles will get OTA updates and which will need to be updated by the dealership.
We should all know how this will work tomorrow or soon thereafter.
Very useful info. Thanks. My dealer indicated they will call me when adapter is in stock and by then should know whether my car (EQB300) will need an update. Pretty much certain that the EQB will not get plug and play.
I just got off the phone with my local dealer and the national customer support so have an update on the situation with the Tesla access:
1. The adaptors are available now as special order parts from the parts department of dealerships.
2. The service advisors in the dealerships have limited information about the rollout, and referred me to the Sales department as the Sales staff have more and more current information about the rollout.
3. The rollout of support is ongoing and they hope to be done by the end of February. (They accidentally transferred me to the national customer support instead of sales, which was able to fill in some additional details.)
4. When they are ready for your vehicle, an email will be sent and a notification posted in the vehicle head unit. That notification should indicate what steps need to be take to gain access to the Tesla network for that vehicle.
No update so far this morning for the App or MBUX but if you already purchased an adapter, all you need is the Tesla app to charge your EQ at a Supercharger. All Mercedes EQ vehicles are officially supported by Tesla Superchargers so you do not need to add a second fake vehicle like the Ford Mach E to fool the app. Just add your Mercedes and you'll see all available Superchargers:
It would be nice if Mercedes let us in on the process. I have never received any communication from Mercedes that they were even considering joining with Tesla. I’m not talking about in the news, but direct communication from them. After all I did buy an EQS 580 so I would expect them to at least notify me of this. I have gotten 99% of info from this forum. Nothing in the app and nothing in the car. Nothing about an adapter.

I completely agree with your assessment. Mercedes has not been handling their EV customers properly since the launch of these vehicles. If they don’t improve quickly, they may lose this customer as my next purchase may not be a Mercedes.
I just confirmed that Tesla Superchargers now appear in the Nav system of our EQS 580 SUV, no software update needed for that but may be required for Plug-and-Charge. I'll find out.
I just got this popup on my phone, called Parts Dept to order it. Here I got this advice from Part Dept: I have to set up an appointment with a service advisor and order the adapter and come in on the day of the appointment to buy the adapter and Technician will set it up with my EQS. That was an instruction from Parts. Anyway, I will stop by the dealer on Monday and make an appointment. Sound more complicate than just show up at Parts, buy an adapter, and start charging at Tesla Stations. Can't wait til Monday.
You do NOT need their help to activate NACS charging. Simply click Manage on the screen above to enable charging at Tesla Superchargers. And you do NOT need to wait for Mercedes to an adapter. You can order the same exact adapter directly from Lectron using this link:
I tested Plug-and-Charge at a Tesla Supercharger this evening and it did not work. I had to open the Tesla app, select the charger, and then start charging through the Tesla app. I was of course able to precondition the battery pack as the Superchargers were about 9 miles away and while only charged for about 15 minutes, I did reach a peak of 143 kW which was much faster than my first time at a Supercharger last month with no preconditioning of the battery pack.
The Tesla app is very easy to use but I'll need to find out why Plug-and-Charge through the Mercedes-Benz app did not work.

Did you get an e-mail from Mercedes to have your MBUX software for plug and charge updated? It wont work from the vehicle until that software is modified.
Update: Stopped by the dealer and talked to SA... Based on the SA, there were some emails to instruct Service Dept. what and how to handle the Tesla charging adapter and update... It's not a clear cut yet, but they put my EQS on their priority order list and hopefully by Thursday or Friday the adapters will be arrived and will get my EQS in for an update with the purchase of a dapter.

No emails or notifications of any kind from Mercedes directly to me about the need for a software update. Has anyone on this forum received such an email? I'm guess not.
That said, I have no issue using the Tesla app to charge moving forward. It's easy to use and will likely provide more details during charging as well as a handy charging summary report of all previous charging:
One issue MB EQ owners will face charging at a Supercharger is our charge port is on the passenger side of the vehicle which often requires taking up two spaces to charge your EV. Tesla charging cables are designed specifically for Tesla vehicles which have the charge ports on the rear-drivers side and are easily reachable with the short Superchargers cable.
As a tip, try to use the left-most charger (facing the chargers) so you don't take up two spaces. I was fortunate to grad the left-most Supercharger last night while testing Plug-and-Charge so I only took up one space. There were five Tesla owners charging at the same time so I was relieved I didn't take up two spots.
A2Z EV has a 16' extension cable that solves this issue at Superchargers or any DC Fast charger. I saw a video that said they will also be offering a 5' version that should cost less and work for most MB EV owners at Supercharger locations. I'll wait for the 5' version as I would rather not carry around a 16' extension cable (heavy). But a 16' extension cable could be just the ticket for someone hauling a trailer or camper and cannot back into a charger without unhitching the trailer.
The A2Z 16' extension cable I posted a link to above is not for use at a Tesla Supercharger. It is a 48A extension cord for Level 2 charging only so ignore the link in that post (I cannot delete or edit the post now).
They are developing a NACS DC Extension Cord for use at a Tesla Supercharger but it is not yet available for sale:

I do not believe a lightweight extension cord is possible The existing cables have a coolant circulating to keep the conductors from overheating, and that is the only reason the cables are relatively small and lightweight. An extension cable would need much larger conductors to handle the same current without active cooling. I recommend staying away from any extension solution.

Superchargers cables are just not long enough unless you take up two spots.
An extension cable may be necessary for those planning to use Superchargers on a regular basis. And I have no doubt A2Z EV will thoroughly test it to ensure it doesn’t overheat before they sell it. The video I posted above from State of Charge testing it showed no issues with overheating.
Time will tell, but I think this will be a popular item for people who own Mercedes and some other brands that don’t have the charging port located at the drivers-side rear where Tesla models have them.
Tesla's new installations already solve the cable length issue. And people in Europe have been living with it for years already and it doesn't seem to be a problem there. There will be some complaints here and there, mostly from Tesla drivers but it will die down in a year or two.
