Sorry if this (or a similar issue) has been posted elsewhere. If so, please point me to that thread.

I have a 2020 1.5 TSI 150hp Kamiq. A couple of days ago, for the first time, I filled up the fuel tank to the max, or until the petrol gun automatically stopped.
The street where I live is currently being reconstructed so this was where I first noticed the issue - a strange sound, like liquid moving around the fuel tank as I was driving.
I understand that the fuel tank is full, but it is something I haven't noticed with any other car I have driven.

Has this happened to anyone else? Please let me know if I should explain myself better, but I hope everybody understood.

Cheers!

Full is never really full 😅, there is always some air available to allow for fuel expension , road bumbs etc etc , I have never heard that sound from the car fuel tank itself but it happened while carrying fuel in jerricans.

Not much to worry about.

I found this thread on another forum - https://www.team-bhp.com/forum/technical-stuff/181312-fuel-slosh-sound-after-full-tank.html . 
Sorry for posting from another forum, I am just using it to better explain the issue I am experiencing and see if there are other Skoda owners who have come across it.

Regards!
