The trick is to NOT plug the charger in until the phone app tells you to. Here are the approximate steps that worked for me. (Sounds like you've already done steps 1 and 2):
1.) Bring up the EVgo phone app on your phone. Do NOT try to use the web site via a web browser. Their web site does not (yet?) have the ability to enter your cars VIN.
2.) Touch the menu (triple equals) button on the upper left. Scroll down and touch 'Vehicles Autocharge+'. Add your cars VIN. Touch the button to request Autocharge+ enrollment. It should indicate your request is pending.
3.) Drive to a close by EVgo station that has CCS chargers. Do not connect the cable to your car yet.
4.) Bring up the EVgo app on your phone again. Press the geolocation arrow to move the map to your location.
5.) On the phone app, touch the button for the appropriate charger and touch the button to pair the car with Autocharge+. It should then tell you to plug into the car.
6.) Snap the CCS plug into your CCS adapter, then plug them both into the car.
7.) App will ask if this is the car you want to pair up. Confirm.
8.) Charging begins.
The thread and your step by step had me excited, and I had 30 minutes to kill, so I tried to set this up. Below is how it almost,
but did not, work.
I have never used EVgo, so downloaded the app, created an account, did the phone number verify and email verify. All from the app. Step 1 done.
Enrolled in Autocharge+ (from the app). Discovered that in the Tesla app if you long-press the VIN you can copy it to clipboard; little details like this make me smile. Pasted that into EVgo (copy/paste so I know it's error-free). The EVgo app told me I needed to plug in. Went to the local EVgo, selected the charger in the app, making sure that the name charger was correct. Steps 2-4 done.
Here's where things went sideways.
Started the session via the app.
Nothing was ever said about Autocharge+. Charging started, I let it run for a couple of minutes, then stopped it via the car, disconnected. Went back through Autocharge+ in the menu. I don't remember
exactly what I did in the app, but it knew I had already set up the car VIN and did not ask for it again. Selected a charger (the same charger), started charging. Again, nothing about Autocharge+. I let it charge for a couple of minutes, then disconnected.
This particular charger was made by Delta. A short (5' tall?) squatty unit. Reading the label on the side I saw "MAXIMUM OUTPUT: 100KW" at which I decided to move to a different model charger adjacent to it. ("Mitzi"). I foolishly did not notice the make/model of the charger. Went back into the app, through autocharge menu, told it I wanted to start charging. In the app I selected the correct charger, and this time it asked me if this is the charger that I wanted to use to enroll in Autocharge+. I thought I was back on track at this point.
The screen on the charger said that there was an error and that I needed to disconnect, wait 10 seconds, then retry. Get in the car, unlock charge port, disconnect, count 10, reselect the charger in the app, tell it it yes this to enroll autocharge+, connect charger. Noticed that the app had a small notice about autocharge+ enrollment complete. Charger screen reported the same problem as before.
At that point the boss called, so free time was up.
Back in the office I called the 877 number. It took only about a minute to get a human, who took my information (couldn't get it from caller ID an my account?). I explained the problem. Then he asked for more information: make, model, year of car, and he politely told me that this car is not supported for autocharge+. I told him that is not true, that I had the CCS adapter and knew of people successfully using autocharge+ at EVgo to charge their Teslas. He politely hummed and hawed for a minute, then told me that he would open a support ticket and that somebody would get back to me.
I just pulled out the phone to download pictures, the EVgo app is still spinning telling me it's setting up autocharge. Timed out after 30 seconds. After downloading the pictures I restarted the app, and notice the message at the top of the screen (see 2nd attachment)? That's the message I had before the second failed session.
So I am not sure what my status is. I might be completely set up for autocharge but cannot use that particular charger for some reason. I might be in some half-way state of enrollment.
Note: in the attached images below the label of the Delta charger is for the first charger in the story above that seems to do nothing with Autocharge+. I did not take a photo of the one that made some progress.
