Problem

audietron type login fails with 401 invalid_client since 2026-05-27. The myAudi app works fine with the same credentials.

Error log

vw-connect.0 Login in with audietron
vw-connect.0 Failed get tokensv2. Please check your if your local time is correct
vw-connect.0 401
vw-connect.0 {"error":"invalid_client","error_description":"Client authentication failed"}

The token endpoint https://emea.bff.cariad.digital/login/v1/idk/token rejects the client_id f4d0934f-32bf-4ce4-b3c4-699a7049ad26@apps_vw-dilab_com.

What I tried

• Updated adapter 0.8.4 → 0.8.5 (same error)
• Changed password in adapter config
• Stopped adapter for several hours (rate limit theory) → same error
• myAudi app on phone works fine → server-side client_id issue

Environment

• Adapter version: 0.8.5
• JS-Controller: 7.0.7
• Node: v22.19.0
• Vehicle: Audi Q5 PHEV (audietron type)
• Region: DE
