Noises after car is turned off!?
So I’ve read this noise is the fuel pump pressurizing after the car is turned off it sounds like air being sucked in. I’ve noticed over time it’s started to sound more like it’s struggling to suck air in (or blow out) when I first purchased the car it sounded less restricted… any advice or suggestions? 2015 Audi S3 stage 2

In the rear the evap emissions pump runs to test the fuel tank system for leaks.
In the front, an after run coolant pump is whirring.
Pumps can get noisier as they age.
Any fault codes?
