Login flow changed at VW, not able to connect anymore

[mwlpeeters]

See issue described in tillsteinbach/CarConnectivity-connector-volkswagen#104

It seems the login flow at VW has changed, the location header is no longer present see logs below.

Same problem here :-(
It looks like same problem was present before: #435

Same problem as well :(

I have the same problem.
Something have changed to weconnect/identity.vwgroup.io, Homeassistants Volkswagen Connect plugin has trouble logging in too.

The VW Android app doesn't seem to be working for me either, so possibly VW have broken their servers (or pushed out an incompatible API change without releasing an update to the app first?)

My android App is working fine, can see battery level, location and more?

I'm not a developer and not sure if that will help and if VWFriends uses the same api, but me be it hellps: robinostlund/volkswagencarnet#329. Would love to track my ID3 again :-) Thanks you Till for you work.

evcc-io has it fixed already

evcc-io/evcc#30281

[ralfschwerdtfeger-blip]

issue occured two days ago for me. I tried to re accept privacy terms on the VW homepage. I had to agree with new Art. 4 Abs. 13 und Art. 4 Abs. 14 EU Data Act.. Though this would help. On the page is a hint, that the user has to chose the right country for right laws to apply. maybe somewhere the country now has to be part of the logon process. I also saw the privacy hint on the main page with parameter ---privacy no-locations but I dont want to try it because I want to store location. maybe there is an other paratmeter for --privacy to use?

migration to this method is needed:

[oldgitdaddy]

Fix created in weConnect python library. Not sure if this is the way to go. @tillsteinbach: please verify, approve and create new release. Otherwise VWsFriend is dead. That would be a pitty, as there is no migration yet to new CarConnectivity platform.

tillsteinbach/WeConnect-python#237

[tillsteinbach]

The problem is that this requires a relogin every two hours. This is very certainly not lasting very long.

[ralfschwerdtfeger-blip]

Meldet sich das Program nicht sowieso zyklisch alle 15 Minuten bei VW an, um die Daten einzusammeln? Da war doch ein Parameter in der myconfig.env. weconnectintervall oder so?

[iLeif-de]

Ich denke das Problem dann die Anzahl der Logins, die dann nötig werden. Bisher geschah das über ein Token, das nur einmal oder zumindest seltener beim Login generiert wurde.

Might help but seems not to be a permanent solution:
evcc-io/evcc#30260

[edit]
Doesn't look like there is a short term solution, VW did that on purpose.
Volkswagen Carnet API shutdown
There is a petition. Not that I believe that will change anything but it's a start to point attention to this issue.

Thank you Till for sharing your work with us. Not your fault that VW broke yours and others tools. It's a shame.

VW zum EU Data Act Hier widersprechen sie sich selbst:
Zentrale Aspekte des EU Data Acts:

- Nutzerkontrolle & Transparenz: Privatpersonen und Unternehmen haben das Recht, auf ihre generierten Daten zuzugreifen und diese zu verwalten
- Fairer Zugang & Nutzung: Nutzer können ihre Daten selbst abrufen oder sicher mit ausgewählten Drittparteien teilen
- Datensicherheit & Rechtskonformität: Der Datenaustausch erfolgt unter strengen Sicherheitsvorkehrungen und gesetzlichen Rahmenbedingungen
- Mechanismen zur Streitbeilegung: Klare Verfahren regeln die Lösung von Konflikten beim Datenzugriff
