Did an autoscan of my Audi S4 today, no faults and AFAIK everything working OK but at the end of the scan I get a popup;

"No ROD file found"

with the description;

" Unable to find a .ROD file for: EV_SoundAc 002005 (AU48)

Please make sure you are using the latest version (including BETA).

If you are using the latest version, please send an Autoscan from this car to Ross-Tech."

At the end of the autoscan is an extra paragraph to previous scans;

"No ASAM data for: "EV_SoundAc" (AU48)
No fault code found."

VCDS is Ver 18.1.0 which I believe is the latest version?

Is this a VCDS fault or something on my car?
