It has happened to me too a few times right after fast charging with a high ambient temp, and it always seems to clear itself after some time to set. First time was right before the 60 day check and while I was about 400 miles from the dealer, right after a big charge at an EA station. It drove and charged fine so I pressed on with no issues. Dealer had the car for about 4 days and could clear the codes, but the charger codes would come back. They had the VW engineers involved too, but were not coming to a resolution and I had to take the car and head 650 miles back home. That was about 2500 miles ago and it has come back a time or two and always cleared.
I got to looking at some other scans that were on the Ross-Tech forum and noticed that every ID.4 I looked at had similar codes on the charger. I think it is a heat, timing, cooling, who knows, type of thing that is triggering it. I really don't think it is a true issue, and some generic thing in the software. But driving those 400 miles with a yellow warning light was not the most comforting
Here is the scan of the charger code before I took it to the dealer:
