I've noticed the same thing. I love the ram-air intake system on the S8, but it collects all kinds of debris. Just yesterday I had the hood open and noticed how much "stuff" was on the air filter elements. I thought, "is it time to replace the filters already?" Nope, I did that last year and only about 11k miles ago, lol.

Seems to be pretty normal. Every year I pull the engine air filter out on my 2021 Allroad and vacuum the detritus out of the air box and clean the lumps off the outside surface of the filter. After vacuuming, the actual air filter looks pretty clean. Given the location of the inlet for the air box it is a bit of a mystery to me how it manages to accumulate so much stuff in there.
If you are in the 'looking for stuff to clean out' mode, flip up the cover on the front cowl (access to the brake MC) on the driver's side and have a look down there. Debris seems to accumulate in there pretty quickly which then blocks the drain holes so that when water drains down in there it turns into a soggy mess which stays wet which is bad for potential body corrosion and the electrical connectors that live down there. I didn't want to go crazy with the hose so I put on a disposable glove to extract as much stuff by hand as possible and then rinsed the area clean by pouring water from a bucket rather than blasting with a hose. Cleaning the engine air filter box was a bit of a cake walk by comparison. Right side of the cowl appears to be less of an issue.
I am wondering whether I should do a pre-emptive flush on the sun roof drains. Blocked sun roof drains leading to water inside the cabin has been a problem on some A4s.
