I've noticed this a few times with the S8 now, although it doesn't really bother me.

Long journey, get home, shut the car down, get out. There's a noise like a motor running around the rear offside wheel/the fuel filler cap. Quite noisily. It runs for maybe 6-8 seconds, then stops, then has another go, maybe four times in total. Suspension isn't moving as far as I can see.

Anyone else experienced this? What is it?
