Sounds like something is draining is the back when i first turn on the car then it stops a few seconds after because my gas gauge goes up a little after the sound stops ima audi noob and first audi any advice?

Fuel pump IIRC. Not a big deal.

That is normal, doesn't mean your pump needs to be replaced. The pump only runs for a few seconds when you first turn the key on, it is just pressurizing the fuel lines/rail and fuel is being returned to the tank.

oddly enough, i have two '00 A4 quattros, One just makes a nice subdued hum when the fuel pump primes, the other sounds much coarser, with sort of gurgling noises.

I've been ignoring it :P
