Hello, had my b8 2.0tdi a while now and when you start the car after a couple of seconds I get a loud humming noise like a pump or something is running constantly, the noise doesn’t change if you’re idle or driving the humming stays consistent, can’t hear it outside the car but can hear it inside, I’m proper stumped by it, has anyone had this before?

Maybe it's the lift pump usually under rear seats & there's 2 on a quattro usually as it's split across the 2 sides due to propshaft.
