In VCDS and on my PolarFIS there are two counters:

* misfires per 1,000 revolutions, which is live and tells you what is happening now.
* Total misfires, which is as the name suggests, the total number of misfires.

Reading around the internet this seems to be somewhat normal for VW, especially a tuned one. Different options like coil packs, spark plugs or a vacuum leak are thrown around, but unless it's a significant number when something really is failing people seem to never get anywhere in 'fixing' it.

I know on my Mk6 118TSI there is a constant background of misfires here and there, but this seems to be "normal". You can read my pondering from nearly a decade ago and I can confirm it's continued much the same ever since. I've chased it with better R8 coils and new plugs and soon to be oil catch can, but it's still there. Many theories around this particular engine abound, but it is what it is.
