Hello everyone,

After my laptop stopped working, I got a new one and installed VCDS on it.

During the diagnostic test on my Passat, the message "CAN: not ready" appeared (photo below).

To rule out the possibility that the problem lies in my own electronics, I repeated the connection test on an Audi A6 from 2012.
With the same result.

I most likely need to perform the initial installation of VCDS now.
because I installed the update from February 2026.

Could you please send the link for the initial installation to my email address?

Thank you for reading.
VG Michi.

Hi, quite sure:
this here
Sure, here is the translation of the text from German to English:

"LG" is an abbreviation for "Liebe Grüße," which means "Best regards" or "Best wishes" in English.
