The fuse for the 12V socket on top of the dash can be in so many different locations! I eventually figured it out thanks to this post and the wiring drawing downloads.
The 12V socket is item U33 on the drawing, in my case (T6 built in mid 2017) it was the SC40 fuse location - it's one of the long J Type 20A fuses. I had to follow the *3 and *4 notes on the drawing to figure out which fuse applied to my age of van. It's so hard to read the fuse numbers in the fuse panel, had to photograph them and then zoom in.
