My comment back on that email was similar. "Been within 150 miles of home and solar home charging. However, also, when I needed you on my 1300 mile round trip to the SF Bay Area, your system let me down. EVERY charging facility had at least one of four charging stands out of commission. The ones that did work were "balanced" and thus charged at a lower speed than posted on the unit. There were even labels, possibly posted by fellow members, which indicated the unacceptable charging rates of around 35 kwh on several of the charging stands. All this meant I had to charge more often wasting over 3 hours one way, turning a typical 12-13 hour trip into a 15-16 hour trip." Response - Crickets -

The only special requirement in the US that I know of is that Tesla seems to want to identify the vehicle manufacturer, so they can exclude non-partner vehicles. I don't know if they are taking a similar approach in Europe or not.

Beyond that, it is kind of guesswork on our part as to the nature of the actual technical difficulty.

So my limited understanding is that randomly generated MAC addresses do indeed conflict from time to time.

I'm thinking that because MAC randomization is a standard feature of Android, and there are a couple billion Android devices in the wild, true randomization with non-repeating addresses is not practical. There are around 300 trillion unique combinations, but that would get eaten into quickly with randomization and disposal.

So while I understand two devices sharing a MAC can be problematic to a network, there must be workarounds in place to solve this occasional conflict.

And remember the MAC randomization is intended to be more of a privacy attribute, not a security attribute. For services like Plug & Charge this remains true. However for Autocharge+, I believe MAC is the only attribute, and in this case is being used as a security feature and as such has been deemed by network professionals as "not secure."

Networks will temporarily disable both devices that share the same mac address. There are up to 281 billion mac addresses, so a collision between randomly generated addresses is very small. Like winning the Powerball lol.

Idk if the Audi/Porsche models have the same issue as the id4 where they all share the same static MAC address. Maybe related to that?
I'm fairly certain that's not true at all. I've read about a "rotating" MAC address, similar to how phones change their MAC address when connecting to networks. But these cars don't all share the same MAC address, they change and that's a reason they can't be used to identify the car. I think that fact got mistranslated and spread.

When I went through this with my Polestar, they ran a test for a week, then they ended the test, then they made an announcement and the access was restored on the announcement day, or maybe a day ahead of time.

I suppose one way to square the circle would be to force ID.4 and Q4 drivers to start charging sessions in the VW/Audi app, since that's paired to the car by VIN and would "sufficiently" ensure to Tesla that you're not trying to charge an unauthorized vehicle (like a Stellantis car or a Leaf with a CCS adapter) instead. In theory someone who owns both an ID.4 and an unauthorized car would still be able to use the VW app to start charging for an unauthorized car but there probably aren't enough people who have an ID.4 and a Wagoneer S to worry about.

Either that or Tesla could just stop doing manufacturer lockout and give up on trying to make whatever deal they think they can get Stellantis to make, since at this point it's clear Stellantis isn't doing a deal even though they plan to put J3400 connectors on their future EVs anyway. I'm not sure what Tesla thinks they're accomplishing at this point by dragging their feet on going fully open; if anything it's helping their new DCFC competitors like IONNA, Mercedes, and Walmart gain a foothold during their cash burn initial buildout.

Because Tesla is using what's essentially CCS, there should be no issues above and beyond what any other CPOs deal with, and our cars charge fine everywhere else without requiring a software update.

So it seems to me it's Tesla's problem to solve, or it has to do with how Tesla is choosing to identify our cars in their quest to maintain gatekeeping.

Outside of Magic Docks, Superchargers are technically only open to "official" NACS partners. The car simply needs to be able to identify itself as a partner brand. Why is handing out that identifier such a big hangup?

And it's probably not related to Plug & Charge, since the Ariya doesn't support it, but can charge.

Here's the relevant text from the linked article:
The summer came and went, and Volkswagen electric car drivers are still unable to charge at Tesla Superchargers. The company asks for "patience" as it works through "technical challenges," and says it still expects Supercharger access to happen this year.

"Volkswagen looks forward to making it possible for ID. Buzz and ID.4 vehicle owners to gain access to the Tesla NACS Partner Superchargers," a company spokesperson tells us. "The timeline has been delayed by technical challenges, and we ask for customers' patience. We still expect to deliver access this year."

Audi and Porsche, which are under the same parent company as Volkswagen, already have access. Volkswagen is one of the last remaining brands, along with BMW, Toyota, and Subaru, according to the Tesla website.

Porsche also seems to be having technical challenges. It's calling its current Supercharger access a "soft launch," meaning its drivers have to use the Tesla app to power up as it works to create the ideal experience on the Porsche app.
It mentions "technical challenges" but nothing about an "app" for VW.

Later, it mentions the Porsche app, but it's not a roadblock. They still get to charge using Tesla's app.

Sounds to me like it's something in the MEB cars themselves, not the phone app.

The thing that is stopping you is that Tesla can tell if you are spoofing (each make has its own unique MAC address prefix [except clones like Honda/GM share one]) and at its whim Tesla will blacklist your car (or sometimes not). They COULD let you charge (and sometimes they actually do) but most of the time they won't let you.

I remember saying a few pages back that we'd get access after my November road trip. It seems to have come true! I'm going to Ottawa Ontario. Charging kind of sucks there and they JUST opened a Supercharger V4 on the way into town, and they're about to open one at the factory outlets mall that I always visit. It would have been so convenient. Alas, perhaps I can use them next summer when I go back.

What app? Are we supposed to be able to charge from the my VW app?

Why can't the ID.4 just charge from the Tesla app, like they now are letting the Porsche cars do?

I am convinced that there are NO technical issues, only financial issues in VW getting a cut of the charging revenue (by initiating from a VW app). From day 1 (and including today) there was/is no reason why you can't charge using the Tesla app the same as if you were using a Magic Dock. But VW is not willing to admit that they can't their app to work so they refuse to throw in the towel.
