I currently have a Stage 2 2.6v APR Golf R 2017 and I notice that every time I stop for a fuel up. The engine has a rough idle feels like a misfire but no engine light has come on. This happens every time when im fueling up. Then goes away after 20mile drive. Anyone experience this issue?

I have the same issue.
MK7R APR Stage 2, V2.5 - 38K miles
It idles rough after fuel up and mostly goes away after driving a few miles.

Honestly I am not sure what it is, but I only noticed it over the last year and I don't recall it happening the first 20-30K miles or so when I was mostly stage I up to that point.
At first I thought it was bad gas at the local Shell station I used for weeks on end when prices went up (prices were very low at that place then) so I initially used a couple of bottles of B12 to see if it would help I also double checked the gap on the plugs which needed a bit of adjusting and both things did help, however it has not fully gone away. I do fuel up at a different Chevron station now. Always 93 oct.
During that time I also did get a fuel sensor level error that I cleared and never came back.

I should add that since then I do have a small misfire at idle and daily driving that will not trigger a CEL or cause the car to drive any different but I don't recall that being the case months before.
