Fuel filler gas release

Has anyone found that when you open the fuel filler cap there is a rush of ‘gas’ (not in the American sense). Almost like opening a pop bottle.

Had my S3 over a year and only noticed in the last month or so. It’s everytime I refuel

Is the rush of air in or out?

Quite normal with all cars.
Happens much more often when fuel is low in the tank.

Light a match and see if it sucks it in or blows it out.

THIS IS A JOKE. PLEASE DO NOT DO THIS!

Don't think mine (A3) sucks or blows....

Surely there’s a breather valve to equalise pressure as fuel is removed from the tank?

Not sure, but mine has also only started to do this recently. I've also lately been hearing a gurgling from the tank and this stops when you release the pressure. I'd definitely say it's gas out as there is a strong whiff of petrol when it does it.

Perfectly normal, mine does it every time I fill up. Nothing to worry about
