The script stopped working again yesterday.

ERROR:vw_connection:Login failed for VW account, Token exchange failed ERROR:vw_connection:Token exchange failed Traceback (most recent call last): File "/home/pi/scripts/vw_connection.py", line 348, in _login raise Exception("Token exchange failed") Exception: Token exchange failed INFO:vw_connection:Something failed__

In Home Assistant they discuss if this is related to the shutdown of VW Carnet: https://github.com/robinostlund/homeassistant-volkswagencarnet/issues/507

While trying to retrieve user identity tokens from https://tokenrefreshservice.apps.emea.vwapps.io/exchangeAuthCode, a 401 response is received with the following payload:

{
   "description":"IdentityKit Response: 401 : {\"error\":\"invalid_client\",\"error_description\":\"Client authentication failed\"}",
   "errorCode":"IDENTITY_KIT_RESPONSE_ERROR"
}

I'm on it right now, let's see if I can get it fixed...

A short update... Authentication works again, but unfortunately, the whole API structure has changed fundamentally. I will continue to work on this, maybe also look at other systems (like OpenHAB), if they already reverse engineered enough of the new API to gain insight from them. But I can't provide a quick solution :-/
